New Version 26.9: Auto Duck and Adjustment Clip

Sun, 27 Sep 2026 00:00:00 -0700

Version 26.9.27 is now available for DOWNLOAD!

Security Notice

All users are encouraged to upgrade. This release fixes flaws in Shotcut’s network downloads:

A failed HTTPS fetch was retried over cleartext HTTP.
Shotcut offered to ignore certificate errors.
An upgrade URL was accepted from a host other than shotcut.org.
A Whisper model was kept even when its SHA-256 did not match the digest shipped with Shotcut.
Refresh Models loaded a downloaded descriptor as QML.

These are fixed in this version. A GitHub security advisory is published and a CVE identifier will be added soon.

New Look

New logo!

Head over to our Press Media Kit page to get various images and color codes for articles/videos.

Improved the appearance of the user interface to be more modern with rounded corners in many places.

Audio Enhancements

Added Automatic Audio Ducking to the Properties of an audio timeline track.

Added a volume control and audio level meter to Timeline track headers. This makes the track header column a mixing console without adding a new panel. The gain filter this adds to the track is keyframable.
Improved audio quality by removing a conversion to 16-bit integer and keeping the pipeline in 32-bit float.
Changed Adjust Clip Gain for timeline clips to require Ctrl+Alt (option+command on macOS) to drag. This avoids inadvertent changes while selecting and dragging clips, so that option defaults on again. A tooltip was also added to the clip’s audio line.

Timeline Enhancements

Added Timeline > Generate > Adjustment Clip. This is a dummy video clip that contributes no video. Its filters apply to the composite of all video tracks below it.
Improved Timeline performance when moving clips to another track, zooming, and undoing many operations (except ripple move and trim).

Other Changes

Changed Settings > Leave Safe Mode to an always-present Allow External Plugins checkbox that defaults to off. This helps prevent some VST2 plugins on Windows and macOS from causing startup and shutdown (including export) problems.
Detect a stuck application startup and automatically disable external plugins.
Added a context menu with Copy to the Missing Files dialog and View > Resources.
Upgraded FFmpeg to version 9.0.

Fixes

Fixed Mask: Draw (Glaxnimate) filter, Operation > Subtract, for 8-bit processing mode (broke in version 25.12).
Fixed using Size, Position & Rotate with Mask: Apply filters (broke in version 25.12).
Fixed LV2 external audio plugins not loading on Windows (unless LV2_PATH is set explicitly).
Fixed opening a project on a mounted CIFS/SMB share on Linux kernel 7.1 and above.
Fixed the VA-API HEVC hardware encoder on Linux.
Fixed Show in Folder not working with non-ASCII characters on Linux.
Fixed Import Subtitles from File not working on Windows.
Fixed a redundant context menu on text edit controls in filters on Windows (broke in v26.8).
Fixed Subtitles showing an incorrect duration (broke in version 26.8).
Fixed moving a Timeline clip next to another with snap while zoomed out possibly inserting 1 blank frame.
Fixed copying and pasting a Timeline transition corrupting audio in the pasted transition.
Fixed the window title bar missing on Linux with Settings > Display Method > Vulkan.
Fixed a marker being unexpectedly deleted when moving a clip to the left with Ripple Markers on.
Fixed keyframes on Timeline > Split after a transition.
Fixed an Export job possibly reporting failure even though the file was completed successfully.
Fixed some buffer overflow security issues in PGM and wipe reading in MLT and in Set Equirectangular.
Hardened MP4 parsing in Properties > Set Equirectangular and the export job context menu.
Fixed projects deleted from disk still appearing in Projects.
Fixed Ctrl+Up and Ctrl+Down not changing the current track when Timeline loses focus.
Fixed Player > External Monitor > DeckLink (and related devices such as UltraStudio) HDMI/SDI possibly deadlocking.
Fixed a nested MLT XML clip’s length (duration) not updating. It now updates when selected, but still needs a manual trim to increase the clip.
Fixed a possible crash when trying to add a subtitle item in the last half second of the timeline.

New Version 26.8: Elements 🔥

Sat, 01 Aug 2026 00:00:00 -0700

Version 26.8.1 is now available for DOWNLOAD!

Elements Panel

Added Elements panel to the File > New and View menus and the Generate buttons. This is a very slim (22MB) stock asset library: emoji stickers, sounds, overlay transitions, animated text, graphics. The content licenses are royalty free, including commercial, and do not require attribution:

Emojis: Open Font License 1.1
Sounds: The Sonniss #GameAudioGDC Bundle Licensing Agreement
Text, Transitions, Graphics: Lottie Simple License

Changes

Added Settings > Graphics Adapter for Windows and Linux (only if multiple GPUs).
Added Shake video filter. First generated UI to be shared and officially adopted.
The --experimental UI generator now also generates a meta.qml. (See View > Application Log to get the temp file names to copy and share these files.)
Improved appearance of tabs and Subtitles in Fusion Dark and Fusion Light themes.

Fixes

Fixed opening a .mlt project file from a file manager on macOS (broke in v26.6).
Fixed corrupt color in dissolve transitions with Settings > Processing Mode > Linear 10-bit CPU.
Fixed the new Reduce Noise: Audio (RNNoise) when the export audio sample rate is not 48000 Hz.
Fixed off-by-one frame errors in subtitle bar in Timeline and Subtitle Burn In video filter.
Fixed all builds missing support for VST2 and LV2 audio plugins. Now install and try the Valhalla Supermassive VST plugin.
Fixed a libGLESv2.dll warning on startup on some Windows systems.
Fixed Motion Tracker keyframes not applying after save/reload.
Fixed manual override QSG_RHI_BACKEND environment variable on Windows.
Fixed Properties > Convert & View > Resources > Convert to keep 10-bit video as 10-bit when using 10-bit processing modes.
Fixed the Crop: Source filter with Preview Scaling and hardware decoder.
Fixed proxy video generated for rotated video (Properties > Rotation) not preserving rotation.

New Release 26.7.30

Thu, 30 Jul 2026 00:00:00 -0700

New Version 26.6: High Dynamic Range

Thu, 25 Jun 2026 00:00:00 -0700

Version 26.6.25 is now available for DOWNLOAD!

External Monitor with a System Display

Three years ago, when we upgraded our UI library to a major new version, we lost support for using an additional system display as an external monitor. Many people were disappointed to lose that feature. Now, after a major change to the video plumbing, it is back!

The External Monitor submenu is moved from Settings to the top of the Player menu. It is incompatible with newly added Settings > Player > Use Old Video Output (provided just in case the new plumbing does not work).

The new plumbing also provides a way to preview HDR video except, for technology reasons, it must be shown in a separate window…

HDR Video Preview and Export

As a quick reminder for those unfamiliar: “HDR” means high dynamic range, not high definition resolution. It is about expanded color and light. A lot of phones and cameras are recording with this today, and many people are not aware until they try to edit and run into problems. Also, HDR game captures on computers is increasingly common. A year ago, we added very limited, hidden support for editing HDR video because, basically, we had no way to display it without a device from Blackmagic Design. Now, there is a way.

Added Player > External Monitor > Preview Window (HDR) that can be made fullscreen.
- It also works for SDR.
- HDR requires a display properly configured with HDR, Native 10-bit CPU or Linear 10-bit GPU/CPU processing modes, and HDR video sources.
- For HDR, only use filters tagged with #gpu or #10bit.
- It does not appear to work on Linux, at least I have not been able to get it working.
- Switching between PQ HDR (HDR10) and HLG HDR requires restarting the app.
- The default shortcut to open or raise the preview window is Ctrl+`. It does not toggle between open and close because raise is more convenient.
- You can move the window by clicking anywhere inside except the controls bar and dragging.
- F toggles fullscreen and Esc also leaves fullscreen.
- Incompatible with Use Old Video Output.
Added Dynamic range to custom Video Mode and Timeline Properties.
This offers SDR, which follows the colorspace, HLG HDR, and PQ HDR.
At this time, Shotcut only supports converting log profile video to HDR with GPU processing mode and HLG HDR video mode. And it cannot convert between HDR formats or combine multiple HDR formats within a project.
Added support for PQ HDR (HDR10) to External Monitor > DeckLink.
Added support for HDR to Export (based on Video Mode and 10-bit processing mode).
Added HDR10 metadata dialogs for External Monitor > DeckLink and Export > Codec.
Export only embeds HDR10 metadata for the libx265 and libsvtav1 video codecs and no hardware encoders.
TODO: Properties > Convert and View > Resources > Convert do not support 10-bit yet; that will be added in the next release.

External Plugins

We added limited support for external audio and video plugins.

“Limited” means it does not support a plugin’s included UI, and our UI generator is new and experimental. That means you can only try it if you are an advanced user who knows how to supply a command line option to reveal the new UI generator. There are many mysterious effects, and uncertainty if things are working correctly. As a result, the user experience is not yet good enough with an increased risk of crash.

“External” means both effects included with Shotcut but not yet available in the UI or plugins that you install yourself to the standard, expected location for your OS.

OpenFX Image Effect Plugins

Added a UI (--experimental not required) for NTSC-rs.
Limited compatibility: not available, seems to do nothing, or makes the video black.
No support for plugins that operate temporally or require multiple image/video inputs.
No support for generators, transitions, or retimers.
No support for the UI embedded in the plugin.
No support for GPU technologies but multi-threaded CPU does work.
Very limited testing. There are many plugins we have not tested especially commercial ones, and we know there are some that do not work.
None are included with Shotcut.

Looks for plugins in the standard folder for the operating system.

Linux	`/usr/OFX/Plugins`
	`/usr/local/OFX/Plugins`
macOS	`/Library/OFX/Plugins`
	`~/Library/OFX/Plugins`
Windows	`C:\Program Files\Common Files\OFX\Plugins`

VST2 and LV2 Audio Plugins

Added a UI for Valhalla Supermassive.
No support for the UI embedded in the plugin.
No support for instruments.
Very limited testing.
None are included with Shotcut.

Looks for plugins in the standard folder for the operating system.

Linux	`/usr/local/lib/vst`
	`/usr/lib/vst`
	`/usr/lib64/vst`
macOS	`/Library/Audio/Plug-Ins/VST`
	`~/Library/Audio/Plug-Ins/VST`
Windows	`C:\Program Files\Common Files\VST2`
	`C:\Program Files\VSTPlugins`
	`C:\Program Files (x86)\Common Files\VST2`
	`C:\Program Files (x86)\VSTPlugins`

Safe Mode and UI Generator

Added menu item Settings > Leave Safe Mode.
This appears if Shotcut crashes within 30 seconds upon startup, which restarts in a safe mode without external (OpenFX, VST2, LV2) plugins.
Added --experimental command line option to try out the filter UI generator. This provides a Manage Add-on Filters dialog to search for effects included with Shotcut or external plugins. After choosing some to add-on, they become available in the regular Filters menu in the current as well as future sessions.

Other New Features

Added Reduce Noise: Audio (RNNoise) filter. More info about RNNoise
Added Settings > Display Method > Vulkan on Linux.
Added Settings > Timeline > Create Transitions on Overlap to disable that feature.
Added support for the .lot filename extension for Lottie animation handled by Glaxnimate.
Added support to load custom filter UIs installed to App Data Directory > extensions > filters. If someone shares a custom or generated UI for an external effect/plugin that seems useful and safe, you can install it here to use it in your Shotcut without needing to use the --experimental mode. This can also be a place to add custom general purpose scripts by making a dummy filter. Use mlt_service: 'shape' as the dummy/no-op backend filter in the meta.qml. Soon we will add a proper scripts panel.
Documented a scripting interface.

Changes

Changed Linux Snap to use a desktop environment file dialog if possible.
Changed the new Log Event shortcut to Shift+D because one conflicted with Remove Subtitle Item.
Moved Declick Audio from the Time category to Audio in the filter menu.
Upgraded MLT to version 7.40.0
Upgraded FFmpeg to version 8.1.2
Upgraded libspatialaudio to 0.4.0
Upgraded frei0r to version 3.2.2

Fixed the Font style from the font dialog is overwritten on filter UI reload on Windows (broke in v26.4).
Fixed hardware scaler on Windows when using Settings > Preview Scaling > Use Hardware Decoder (broke in v26.4).
Fixed mouse wheel and keyboard not incrementing/decrementing numeric fields in filter UIs (broke in version 26.4).
Fixed moving clips may create a very long gap.
Fixed Player > External Monitor > DeckLink (and related such as UltraStudio) HDMI/SDI may deadlock.
Fixed export with libopus audio codec warns about frame_duration.
Fixed incorrect current track after moving clip to another track.
Fixed undo after changing Video Mode corrupts the timeline.

Fixed mouse wheel not scrolling a filter’s UI within Filters.
Fixed 10-bit H.264 encoder fails with hardware encoding on.
No H.264 hardware encoders support 10-bit; this change simply makes it use software encoding with x264.
Fixed Export > Ogg Vorbis with Cover Art fails (no longer fails but our Ogg integration does not support cover art).
Fixed Export > From > Marker using the Reframe output video filter with keyframes.
Fixed some toolbar icons’ tooltips not showing keyboard shortcut.
Fixed Zoom Timeline to Fit may not scroll to start.
Fixed a crash using some Markers actions with nothing open.

Fixed changing many things in Properties enabled Filters that were disabled.
Fixed crash in Text: Rich filter on some Linux/Wayland versions.
Fixed toggling visibility of other tracks in Timeline could make an audio clip with an image appear on top.

Version 26.1.30 is now available for DOWNLOAD!

Hardware Video Decoding!

“What took so long?” you might ask. A good way to manage it across all operating systems and GPU vendor APIs. We have a FAQ topic about this. Management comes in the forms of operating system abstraction APIs, hardware scaling, and a threshold limiter.

Settings > Preview Scaling > Use Hardware Decoder

Enabled by default, except with NVIDIA on Linux.
Uses VA-API on Linux, Media Foundation on Windows, and Video Toolbox on macOS.
Only supports codecs your hardware can decode; automatically falls back to software decoding if needed.
May not provide a dramatic speed boost unless you use Linear 10-bit CPU processing mode or have a low-powered CPU.
Has limited impact on seeking and scrubbing—using proxies is still recommended for smooth editing.
Reduces CPU usage, which can help lower battery drain and keep your system cooler.
Not integrated with GPU processing mode via 0-copy.
Transferring uncompressed video between CPU and GPU RAM can be a bottleneck, so this feature is limited to preview scaling or 1080p-60fps (or lower) sources.
Advanced users can remove the 1080p60 limiter by setting environment variable MLT_AVFORMAT_HWACCEL_PPS=0.

Export > Codec > Use hardware decoder

Disabled by default, as it can sometimes increase export times.
No resolution or frame rate limits.
Can reduce CPU usage during export, which may be beneficial for some workflows. (Tip: Avoid exporting videos on your lap for long periods!)
The setting is persistent and will be remembered between sessions and projects.
Feel free to test it on your system to see if it offers benefits for your specific hardware and workflow.

What’s This?

This is contextual help! It lets you get assistance for a specific item in the user interface—just click the “What’s This?” icon, then click on the UI element you want to learn about. Usually, this opens a web browser to the relevant documentation, but for some items like toolbar buttons, it may show a tooltip instead if more detailed documentation isn’t available.

Comprehensive documentation is essential for this feature to be useful. Many users aren’t aware that documentation exists, but it’s now much more complete and accessible. The documentation is available on the website, and a PDF is generated automatically from the forum-wiki-based content. Additionally, the forum offers a Claude AI bot that can help answer questions using the documentation and release notes.

Other New Features

Added converting a project between GPU & CPU processing modes.
Added the Blend Mode filter and track option for the Linear 10-bit GPU/CPU processing mode.
Increased the maximum resolution in Video Mode and Export to 8640 for 8K VR180 video.
Added Settings > Language > Chinese (Simplified).

Changes

Improved the appearance of outline in the text filters: Text: Simple, Typewriter, GPS Text, Subtitle Burn In and Timer.
Changed bulk proxy generation (when you switch Settings > Proxy > Use Proxy ON) to update clips. (Previously, you had to turn proxy mode off and back on again to start using the proxies. That requires reloading the project each time, which was a real drag.)
Changed Timeline > Add Generator and New Generator > Add To Timeline to not seek. This leaves the playhead over the clip it just added to facilitate preview and reduce steps.
Changed simple keyframe defaults in Mask: From File filter to be more convenient for multi-track transitions.

Fixes

Fixed Brightness filter with a reduced level is different when there was clip with transparency above it (broke in v25.12).
Fixed Timeline > Record Audio would always reset the selected audio device and require re-selection (broke in v25.12).
Fixed the Mask: Apply video filter in 10-bit processing modes (incomplete in v25.12).
Fixed macOS app signing.
Fixed a crash in the scrub-bar on a very long playlist.
Improved the reliability of opening URLs (Help menu), Show In Folder, Open With in the Linux AppImage/portable/Snap.
Fixed app not responding while enqueuing very many proxy jobs.
Fixed Previous/Next in Subtitles may be unreadable on some themes and OS.
Fixed reading the alpha channel in 12-bit ProRes with alpha.
Fixed the Halftone video filter was not copying input alpha channel.
Fixed it was possible to use Split on a locked track in Timeline.
Fixed glitchy export job progress and estimated remaining time.

New Version 25.12: Higher & Higher

Tue, 30 Dec 2025 00:00:00 -0800

Version 25.12.31 is now available for DOWNLOAD!

Higher Bit Depth: 10-bit Video CPU Pipeline

What is “bit depth?” That is the number of colors or video brightness levels. 8-bit has only 256 values per color component, for example, red/green/blue. 10 bits has 1024 levels. Previously, 10-bit video sources were only partially supported using GPU Effects and only GPU filters. Without GPU Effects (CPU), in order to stay in thee 10 bit space, you could only use filters with the #10bit tag but no transitions or track blending/compositing. Now, we have ported many CPU video effects to support 10- and 12-bit video sources including transitions and track blending. Also, the #10bit CPU video filters also work properly with the experimental GPU processing. Not all of the video CPU filters have been converted; many of them come through another software project that does not support it. However, we were able to convert many for this release or at least mark them as safe for a 10-bit project.

Higher Image Quality: Linear Color Processing

Any mixing of pixels with a color space’s gamma is not ideal, can cause color distortions, and is technically incorrect. This pixel mixing occurs whenever images interpolated, for example scaling, blurring, and sub-pixel positioning, as well as with track blending/composition. Previously, only GPU Effects and video filters in the GPU category operated in linear color. Now, there is an option to use it outside of the GPU processing. But when using the GPU, the handoff of the video from GPU to CPU now stays in the linear color transfer.

There is a new sub-menu in Settings > Processing Mode with options:

Native 8-bit CPU (fast, flexible)
Native 10-bit CPU (slower, better)
Linear 10-bit CPU (slowest, best)
Linear 10-bit GPU/CPU (Experimental)

Non-linear “native” options are still included because there is a signficant performance decrease when using linear (more conversions). We have a plan to improve performance for the next release. 8-bit is still included because it is more “flexible” by including more video filters. Of course, you can use an 8-bit video filter in a 10-bit, but the quality of the video clip or track will suffer a reduction in bit depth.

Other New Features

Added a drop-down to the Filters menu’s Video button to more conveniently browse appropriate filters for the current processing mode.
- GPU
- 10-bit
- Color
- RGBA
- YUV
Changed the Filters menu to default to Color filters in the Color layout/workspace and Audio filters in the Audio layout.
Added a visual preset browser for New > Image/Video from HTML generator. To add a thumbnail for your custom preset add a file named <preset-name>.webp in the preset folder.

Added 2 new HTML presets: Chrome and Neon Flux!

Added Minimize Shotcut and Record Audio to Screen Snapshot and Screen Recording.
Added support for nvenc to Screen Recording on Linux/X11.
Added support for mov_text and SSA in Properties > Extract Subtitles.

Changed the VP8/9 WebM presets to offer greater control over quality and bitrate.
Changed New > Animation (Glaxnimate) to Drawing/Animation to clarify that this is not only for animation.
Changed New Project > Project name to not permit ? to fix unloadable project.
Changed the Opacity video filter’s maximum to 200% to support reducing translucency.
Improved VA-API hardware encoder compatibility on our Linux AppImage, Portable, and Snap builds.
Changed Screen Snapshot on macOS to show a toolbar to choose rectangle or fullscreen and whether to minimize.
Removed Screen Recording on Windows 10–Snipping Tool does not support it.
Upgrade zimg (used to convert HDR to SDR and to and from linear color) to version 3.0.6.

Fixes

Fixed dissolve transition damages color (broke in v25.10).
Fixed export on Windows not working with some special characters in a filename (broke in v25.10).

Fixed crash when clicking Cancel in the Set Duration dialog (also related to very long or invalid duration).
Fixed a memory leak in Filters panel.
Fixed a possible crash in the player’s scrub bar.
Fixed the vertical position of the shadow-clip when dragging a clip to a timeline with a subtitles track.

New Version 25.10: Please Mr. Please

Fri, 31 Oct 2025 00:00:00 -0700

Version 25.10.31 is now available for DOWNLOAD!

Added New > Image/Video from HTML

For example, the 3D-extruded gold text in this image:

This requires Google Chrome or Chromium.
Please see the stock Presets for examples.
It defaults to a transparent background!
The stock presets also demonstrate a template facility for up to 3 lines of text. You can make your own templates by using %1, %2, or %3 as placeholders in the Body field.
It is designed to make it easy to copy from codepen.io, but Shotcut does not include pre-preprocessors for things like SCSS or TypeScript. Therefore, in codepen.io click the V button in the top right corner of the edit block to choose View Compiled before copying.
This does not support WebGL or embedded video.
Generate Video is limited to 15 frame-per-second for performance reasons. A somewhat modern or fast computer and SSD hard drive are recommended.
Generate automatically opens the result in the Source viewer so you can preview it with its HTML for revising if needed. Once you add it to Playlist or Timeline, Properties now reflects the image or video and no longer shows the HTML inputs.
This is not available in the Linux Flatpak.

Added Text to Speech to Notes and Subtitles

Your browser does not support the audio element.

This uses Docker like a plugin framework. The engine for this is Kokorodoki, and the model is Kokoro–both of which are not made by us. Do not ask us for more languages or voices.
There are Docker installers for Windows and macOS from docker.com. For Linux, it is usually preferable to get it from your distribution but ensure you get the real docker and not podman or the desktop icon dock bar. On Debian-based systems, it is the docker.io package.
The quality with subtitles is heavily dependent upon the timing and duration of each item. If it sounds choppy or cut-off, you either need to increase the speech speed and/or the item durations. Also, multi-line subtitle items are discouraged because that introduces a pause as it thinks it is like a new paragraph.
This is not available in the Linux Flatpak.

Added New > Screen Snapshot and Screen Recording

On Windows, Screen Recording simply launches Windows’ Snipping Tool provided by Microsoft. It does not create a job in Shotcut or automatically open the capture file when done. You need to either configure Snipping Tool to save to a file or click the notification that appears to view it from which you can save it. Then, you need to manually locate it and open it in Shotcut using either File > Open, the Files panel, or drag-n-drop from Explorer.
On macOS, Screen Recording uses the screenshot utility from Apple. It starts a job in Shotcut’s Jobs panel that you must right-click and choose Stop This Job.
On Linux, Screen Recording uses the bundled ffmpeg if using X11. On Wayland, it uses GNOME Shell, KDE Spectacle, or obs if neither of those. With X11 or GNOME/Wayland it starts a job in Shotcut’s Jobs panel that you must right-click and choose Stop This Job.
Not yet available for Flatpak on Linux.

Other New Features

Added a Text: Typewriter video filter and New Generator > Text > Typewriter.

Added Open With and Reload to Properties.
- You can think of this as “Edit With” especially useful for images and audio files.
- There is a file watcher upon opening with another tool as long as selection (Properties) does not change. If it does, you can use Reload. This does not yet reload–whether manual or automatic–every clip object based on this file.
- This is not available in the Linux Flatpak.

Changes

There were some changes in the engine to prepare for video processing improvements in a future version. As a result, there are a different set of blending modes in Timeline track Properties and the Blend Mode video filter.
Changed Export > Export File to Export Video/Audio.
Changed Export > Search to include file name extension.
Changed Settings > Time Format to default to Clock.
Changed Settings > Timeline > Adjust Clip Gain/Volume to default OFF.
Changed Settings > Timeline > Automatically Add Tracks to default ON.
The minimum Linux glibc version increased for this release to 2.35 (Ubuntu 22.04).
Upgraded to FFmpeg 8.
Upgraded librarues: SVT-AV1, libaom, dav1d, libvpx, libwebp, and whisper.cpp.

Fixes

Fixed export with ‘&’ in the file path or name.
Fixed the alpha channel when decoding Ut Video with alpha channel.
Fixed starting the Linux AppImage if AppImageLauncher is installed.
Fixed Rejoin with Next Clip duplicates filters.
Fixed advanced keyframes for Text: Rich.

New Version 25.08

Sat, 16 Aug 2025 00:00:00 -0700

Version 25.08.16 is now available for DOWNLOAD!

This version fixes new bugs in the previous version 25.07. Details:

Fixed Gain/Volume filter from a previous version project does not show its UI or keyframes (broke in v25.07).
Fixed artifacts in Gain/Volume, Fade In Audio, and Fade Out Audio filters (broke in v25.07).
Fixed frequent crashing in Fedora Linux RPM package (broke in v25.05).
Fixed converting BT.709 color space to BT.2020.
Added BT.2020 color space support to the preview.
Added Embed Markers as Chapters to export job context menu.

New Version 25.07: Hot Hot Hot

Sat, 26 Jul 2025 00:00:00 -0700

Version 25.07.26 is now available for DOWNLOAD!

1 hot for the new Speech to Text model downloader
2 hots for the new System Fusion and improved System UI themes
3 hots for your CPU cooking on the new Outline video filter!

Added a Whisper.cpp (GGML) model downloader to the Speech to Text dialog.
A model is no longer included in the download and installation reducing their sizes.
Improved the System theme to follow the operating system palette on Windows (darker and more contrast), and improved its appearance on macOS dark mode.

Added Settings > Theme > System Fusion that combines the operating system palette with the monochrome, symbolic icons of the Fusion themes.

Added an Outline video filter that uses the input alpha channel–useful with rich text or assets with a transparent background.
This means that, like Drop Shadow, it will not work as expected when used after a text filter on a video or image clip. Rather, you must use a text clip (transparent color generator with text filter) on an upper track.

Other New Features

Added the ability to drag the waveform peak line to adjust audio gain.
Added Settings > Timeline > Adjust Clip Gain/Volume to turn off the above.
Added rolling an edit/trim to Timeline:
Hold Ctrl (command on macOS) while trimming to simultaneously trim the neighbor clip.
Added a Soft Focus filter set.
Added Audio/Video duration to the Slideshow Generator dialog, defaults to 4 hours.
This facilitates using Slideshow Generator to make transitions between everything when including both video and images. (It still respects the source duration and in & out points; duration here is a maximum.)

Surround Sound Mixing Improvements

Added fader and surround balance to the Balance audio filter if channels > 2.
Added Channels toggle buttons to many audio filters:
- Band Pass
- Compressor
- Delay
- Downmix
- Equalizer: 3-Band
- Equalizer: 15-Band
- Equalizer: Parametric
- Expander
- Gain/Volume
- High Pass
- Low Pass
- Limiter
- Mute
- Noise Gate
- Notch
Added support for 4 channels in the Copy Channel audio filter.

For example, now you can:

Copy stereo music to the rear channels and use the fader in the Balance filter to reduce its volume,
Downmix spoken word into the center channel and apply a Band Pass filter to it, and
Route music or sound effects to the low-frequency channels and apply a Low Pass filter to it.

Other Improvements

Changed the default Export > Audio > Rate control to Average Bitrate for AAC, Opus, and MP3.
Added the ability to add/use multiple Mask: Apply filters.
Added support for Scrub While Dragging to trimming on the timeline.
Added hold Shift to ripple-trim when Ripple is turned off.
Added French (Canadian) and Lithuanian translations.

Fixes

Fixed Mask: Apply with multiple Mask: Simple Shape (broke in v25.05)
Fixed exporting projects containing only Generator clips on Windows (broke in v25.05).
Fixed converting 10-bit full to limited range (broke in v25.01).
Fixed dropdown menus using Settings > Theme > System on Windows.
Fixed Load Keyframes from Motion Tracker is empty after opening something into the Source player.
Fixed Balance and Pan audio muted channels if audio channels > 2.
Fixed Export > Use hardware encoder fails with H.264 on macOS 15.
Fixed Properties > Convert or Reverse for iPhone 16 Pro videos with Ambisonic audio.
Fixed a single frame fade out filter would either mute or make black.
Fixed repairing a project (e.g. broken file links) with proxy turned on.
Fixed doing Freeze Frame on the first frame of a clip.

New Version 24.10: Whisper to a Scream

Tue, 29 Oct 2024 00:00:00 -0700

Version 24.10.29 is now available for DOWNLOAD!

Speech to Text

Shotcut gets its first AI based on OpenAI’s Whisper, courtesy of the whisper.cpp project. This is available through Subtitles > Speech to Text menu item or button: .

Our builds include a basic model that has decent speed and accuracy but not a big size. (You can think of the model as the brain.)
You can download a bigger and better better brain (model) in ggml format and configure it in the Speech to Text dialog, but it will be slower.
The dialog creates two jobs that appear in the Jobs panel: one to export audio and another to convert to text.
The results are added to the Subtitles panel as a new top-level Subtitle Track.
Currently, the only GPU our build supports is Apple Silicon. Otherwise, it is heavily multi-threaded on the CPU.
Known quirk: subtitle items sometimes start earlier than expected. Timing is provided by the model and tool, and we lack the skills and resources to improve this.
Expect there to be occasional errors. Like humans and non-ideal conditions, it is not perfect. We will not take action on bug reports about some piece of audio not converting to the expected text.
OpenAI has made some warnings about the usage of their Whisper models:

In particular, we caution against using Whisper models to transcribe recordings of individuals taken without their consent…. We recommend against use in high-risk domains like decision-making contexts, where flaws in accuracy can lead to pronounced flaws in outcomes.

Transition Improvements

Ripple Delete a transition restores the entirety of the clips included in the transition.
Lift (non-ripple delete) a transition no longer leaves a gap; the gap is filled with the adjacent clips.
Moving an adjacent clip away increases the transition duration instead of detaching and leaving a gap.

Other Improvements

Removed the Export > Video > Resample button. Now, there are simply ignorable inline warnings when making certain changes.
Added File > Show Project in Folder to menu.
Added a decimals <number> option to numeric keywords in the GPS Text video filter.
Changed Recent Projects to Projects: items in this view no longer disappear as Recent reaches its maximum length and old items are removed.
Added a Remove action to the context menu in Projects.
Hide the Reframe video filter and button if GPU Effects is on.
Upgraded FFmpeg to version 7.1.

Fixes

Fixed a crash doing when doing more than one Playlist > menu > Add Selected to Slideshow. In theory, this could fix other random crashes in Timeline.
Fixed a crash opening a project containing a subtitle track with no items.
Fixed odd value for computed width in Reframe output video filter causes export to fail.
Fixed Reframe visual control can create odd-valued dimensions.
Fixed AVCHD video frame rate is double (could fix other formats).
Fixed making a proxy video for a iPhone 16 Pro video containing spatial audio.
Fixed GPU filters paste below non-GPU filters.
Fixed Slideshow Generator dialog is too tall with vertical video mode.
Fixed GPS Offset would reset in GPS Text video filter.
Fixed the maximum allowed Time in the Time Remap filter to prevent white frames.

New Version 24.09: Reframe

Fri, 13 Sep 2024 00:00:00 -0700

Version 24.09.13 is now available for DOWNLOAD!

Fixes For Major New Bugs

This is a quick followup release to version 24.08 that introduced a few major new bugs:

Fixed seeking and frozen video with some files or scenarios.
Fixed Reverb audio filter missing on Windows.
Fixed wrong frame rate for Android Camera videos.
Fixed may fail to launch on macOS 11 (broke in v24.06).

Other Fixes

Fixed color in Export > Presets > stills > JPEG preset.
Fixed audio-only WMA file with DTS audio not playing.

Improvements

You can also use Ctrl with the mouse wheel.
Added a Reframe video filter (Output only) and Export > Video > Reframe button.
Added Export > Video > Resample with warning dialog to enable the oft-misused export video resolution, aspect ratio, and frame rate fields.
Added a warning dialog when changing Settings > Video Mode or Timeline > Output > Edit with a project open.
Upgraded MLT to version 7.28.0.

New Version 24.08: Subtitles

Thu, 29 Aug 2024 00:00:00 -0700

Version 24.08.29 is now available for DOWNLOAD!

Subtitles!

Added View > Subtitles.
Added Subtitle Burn In video filter (only works on Output track).

The Subtitles panel can be used to add subtitles to a project. Subtitles can only be added to the Timeline. They can not be added to the playlist or clips. We recommend to save subtitle editing until the timeline editing is complete because moving or cutting clips on the timeline will break the subtitle synchronization.

To start editing subtitles, click the “add” button and give the subtitle track and name and language. After the subtitle track is created the subtitle track area will appear in the timeline above the top video track. Multiple subtitle tracks can be added. But only the currently selected subtitle track is shown in the Subtitle Panel and the Timeline.

Click the “Add subtitle” button to make a new subtitle item at the cursor position. Then type in the “Current” text area to add the text.

Subtitles can also be imported. Supported subtitle import formats include: SRT, VTT, ASS, and SSA. Subtitles are imported at the current cursor position. So be sure to place the cursor before importing subtitles from a file.

Export

Subtitles can be exported to a file. Subtitles are exported in SRT format.

When exporting a Shotcut project, subtitles will be embedded in the output file if the file format supports it. Formats that commonly support subtitles include MKV, MOV, and MP4. You can disable this using the checkbox at the bottom of the Export > Other tab. You can also enter the text sn=1 in the other box to disable them.

Subtitle Burn In Video Filter

The Subtitle Burn In filter can only be added to the Output track. The filter allows you to select an existing subtitle track, and overlay the subtitle text on the project video.

Other Changes and Fixes

Added a Power (W) ( #gps_power#) field to the GPS Text video filter.
Now Enter or Return in Filters > search changes focus to the search results.
Now Up or Down in Help > Actions and Shortcuts > search changes focus to the search results.
Changed the Softness to 0 in the Obscure With Blur and Obscure With Mosaic filter sets.
Fixed the Linux portable, AppImage, and Snap fail to launch on some systems (e.g. Ubuntu 24.04) with Qt 6 and Wayland.
Fixed occasional audio pop/click with some media files especially with uncompressed audio.
Fixed lag in Filters > search.
Fixed a disabled Crop: Circle or Crop: Rectangle video filter becomes enabled when reselected.
Fixed the hevc_toolbox hardware video encoder fails detection on some Intel Macs.
Fixed file dialogs open slowly in the Linux AppImage.
Fixed overriding Properties > Rotation on a proxy video whose default is not 0 exports with wrong rotation. This bug affected the creation of the proxy and thus requires making a new proxy, which is easier said than done on Windows due to file locking. Properties > Proxy > Disable Proxy on the affected clips is a workaround if you do not turn off proxy completely.
Fixed Properties > Proxy > Make Proxy does not override a DJI- or GoPro-provided proxy video.
Fixed 59.94 fps in Matroska falsely identified as variable frame rate (broke in v24.06).
Fixed mono audio assets not playing through both stereo channels (broken in v24.06).
Fixed Open Other > Audio/Video Device > Video Input on macOS (broke in v24.06).
Fixed spinboxes on Settings > Theme > System on Windows takes too much space from the numeric field (broke in v24.06).
Fixed many audio filters missing for Windows on Arm computers (broke in v24.06).
Fixed setting the audio language in Export > Other using alang=.
Fixed right Alt key (AltGr) for text input in some languages instead keyboard shortcuts/actions in Windows.
Fixed the Convert dialog when dropping hangs Windows Explorer until the dialog is closed.
Fixed Add Keyframe at Playhead for some filters, for example Color Grading.
Fixed enabling keyframes in Color Grading adds 2 keyframes.
Fixed the modal font dialog on Linux can be behind main window making Shotcut not responsive.
Upgraded MLT to version 7.26.0.

New Version 24.06

Wed, 26 Jun 2024 00:00:00 -0700

Version 24.06.26 is now available for DOWNLOAD!

Windows on Arm

Hurrah for new Qualcomm Snapdragon X chip! Since there are now good Arm64 CPU systems for Windows, we added a native build for Windows on Arm64 CPU. Treat this as a beta. Known issues are there is no hardware encoder, and some audio filters are missing.

New Stuff

Added SVT-AV1 encoder (faster non-hardware AV1 encoder).
Added support for AVIF (AV1) images.
Added a Drop Shadow video filter that uses the input alpha channel. (This means that it will not work as expected when used after a text filter on a video clip; rather, you must use a text clip on an upper track.)
Added a Vibrance video filter. This is similar to Saturation, but Vibrance is sensitive to the current saturation instead of adjusting all values equally as in saturation. This is especially helpful to prevent affecting skin tones.

Added the Mid-Side Matrix audio filter for processing these kinds of microphones into proper stereo sound.
Added Keyframes > Scrub While Dragging.
Added Playlist > menu > Columns.
Added support for DJI LRF (MP4) files as a proxy.

Fixes and Changes

Improved handling for some variable frame rate videos. Now, Properties tries to show the file’s target frame rate and extends the variable detection logic to include strange average frame rate values (what previous versions showed in Properties).
Changed Playlist Tiles view mode to show Date instead of In/Start.
Fixed using graphics (text, image, etc.) on upper video track with GPU Effects.
Fixed an off-by-one frame bug in the duration for Glaxnimate animations.
Fixed Undo does not work for time filters.
Fixed spamming (Undo) History when using the timeline fade controls.
Fixed preview color with GPU Effecs is inaccurate.
Fixed Timeline > Select None does not clear the Filters panel or VUI.
Fixed single click does not reset a multi-selection.
Fixed Export > Codec > Quality hint not updated after changing Rate control.
Fixed Properties > Proxy > Make does not regenerate if already exists.
Fixed changing Properties (except Speed) affects clips on other tracks with Ripple All Tracks turned on.
Fixed drag from Source and drop to Source changes Playlist.
Fixed Automatically Add Tracks changes the current video track, which can cause unexpected behavior with Properties > Speed change, for example.
Fixed files generated automatically in the project folder (.stab, .rawr, etc.) are incorrectly generated in the app data’s autosave folder in the app session immediately after Shotcut recovers an auto-saved project.
Fixed changing Properties can delete a timeline clip.
Fixed selected filter changes unexpectedly by changing tabs or clicking filter categories.
Fixed Properties > Audio > Track > All.
Fixed the project folder when running an autosave-recovered session.
Fixed Settings > Timeline > Auto Add Tracks creates too many tracks when drop multiple clips to Timeline.
Fixed new Settings > Time Format not used in several places.
Fixed View > Application Log > Previous not working after the first time.
Fixed Properties > menu > View Bitrate hiding the first second.
Upgraded Qt to version 6.7 on macOS, Windows, and Flatpak.
Upgraded dav1d to version 1.4.2.
Upgraded FFmpeg to version 7.0.
Upgraded OpenCV to version 4.9.0.
Upgraded VMAF to version 3.0.0.

- Fade Out Video
- Text: Rich
- Size, Position & Rotate
- White Balance
Added Apply Copied Filters to Timeline > menu > Edit and context menu that works with multiple selected clips.
Upgraded MLT to version 7.24.0.

Fixes

Fixed crash if the Keyframes panel is in a tab group along with Filters.
Fixed Elastic Scale video filter can distort with preview scaling.
Fixed dropping incompatible video file may not prompt conversion.
Fixed color in Properties > Convert > Best if input video is BT.709 without signaling.
Some fixes for Settings > Audio Channels > 4 (quad).
Fixed changes in Filters cannot after moving the clip on the Timeline.
Fixed Zoom Timeline to Fit sometimes incorrect.
Fixed batch analysis for Stabilize video filter on export with project folder.

New Version 24.02: Go Where You Wanna Go

Thu, 29 Feb 2024 00:00:00 -0800

Version 24.02.29 is now available for DOWNLOAD!

Ambisonic Audio

Ambisonic spatial (spherical) audio is often used with 360° video whether output as spherical or reframed to a rectangle. Adding support for Ambisonic facilitates 360° video workflows with Shotcut.

But also the new Ambisonic Decoder audio filter is part of an affordable, simple way to record (e.g. GoPro MAX, Zoom H3-VR) Ambisonic audio and convert it to 5.1 surround. FYI, YouTube supports 5.1 surround on most TV-oriented devices (smart TVs, streaming boxes, game consoles). And Windows has something called Sonic to listen to surround through headphones. The new filter can also be used to listen to Ambisonic through headphones (binaural), to rotate the sound when you rotate spherical video, and to pan stereo or surround audio output for reframed 360° video. For example:

Added Settings > Audio Channels > 4 (quad/Ambisonics).
Added Ambisonic Decoder audio filter that converts to binaural, stereo, quad, Ambisonic, or 5.1 surround. When Ambisonic mode is chosen, it is an Ambisonic panner.
Added Ambisonic metadata to Set Equirectangular if there is a track with 4 audio channels.
Added Copy Parameters to 360 video filters to use with Ambisonic Decoder > Paste Parameters.
Shotcut only supports first order Ambisonics at this time.

More New Stuff

Added support for AMD AV1 hardware encoder on Windows (av1_amf) and Linux (av1_vaapi).
Added automatic vertical scrolling to Timeline when moving a track.

New Version 24.01: Round and Round

Sun, 28 Jan 2024 00:00:00 -0800

Version 24.01.28 is now available for DOWNLOAD!

New Stuff

Added Player > Loop (\) and Player > Set Loop Range to the menu and player controls.
Added Timeline > Selection > Group/Ungroup (Ctrl+G, command+G on macOS). This is basically a saved multi-selection system. So, the operations it supports are all those available for multiple selection. That does not include trim, Filters, or Properties at this time. Hold Alt (option on macOS) to select an individual member of a group. Hold Alt+Ctrl (option+command on macOS) to multi-select only certain members of a group.
Added support for multiple selection to Split At Playhead.
Added Timeline > Edit > Split All Tracks At Playhead (Shift+S).
Added Edit > Undo and Redo support for adding, removing, changing, and disabling Filters.
Added Timeline > Edit > Nudge Forward (.) and Nudge Backward (,).
Added Pause and Resume to the context menu in Jobs.
Added Settings > Backup with options for:
- Manually
- Hourly
- Daily (default)
- Weekly This creates a backup of the current project file in a manner similar to File > Backup and Save except it is automatic now unless Manually is chosen.
Added File > Other Versions submenu that tries to find similarly-named project files in the same folder create by Shotcut backup or recovery mechanisms.
Added Settings > Player > Audio API on Linux and Windows. Basically, this makes the --SDL_AUDIODRIVER command line option available in the Settings menu.
Added a Previous button to View > Application Log dialog that goes to the log file created by the previous app session. Now, on startup, Shotcut makes a backup of shotcut-log.txt to shotcut-log.bak.
Added a Copy button to all text viewer dialogs that does the same thing that the non-obvious Select All and Copy actions in the context menu.

Fixes and Changes

Fixed a possible crash when opening project.
Fixed a crash in Playlist > menu > Add Selected to Slideshow when something is playing.
Fixed a possible crash in Timeline > Split or trim actions if the clip has certain filters with keyframes.
Fixed some bugs in Undo after moving clips on the Timeline.
Fixed sometimes (25 fps) frames are dropped and others repeated in Export on macOS.
Fixed proxy generation failing with NVENC if Settings > Proxy > Use Hardware Encoder is on.
Fixed proxy generation failing for videos with full range color on macOS with Settings > Proxy > Use Hardware Encoder turned on.
Fixed 10-bit Export with NVENC (NVIDIA) encoders.
Fixed Layers > New > Emoji is disabled in Glaxnimate on Windows.
Fixed distort mode in Size & Position GPU filter.
Fixed zombie values in Time Remap filter while working with keyframes.
Fixed saving B frames in custom Export preset with hardware encoder.
Fixed toggling Export > Use hardware encoder resets all options to defaults.
Fixed Export > Each Playlist Item > Directory incorrectly shows a filename.
Fixed intermittent crash moving a clip on the Timeline.
Fixed Playlist > Select All and Remove All are disabled until selection changes.
Fixed some filter parameters’ sliders may overflow using new keyframe easings that over- or under-shoot.
Changed the name of the Declick time filter to Declick Audio.
Changed the player controls to automatically adapt to 2 rows so the In Point and Selected Duration show more reliably.
Changed the low memory warning dialog to automatically close itself when the free memory becomes high enough.
Changed the low memory detection to automatically pause and resume a currently running job as the free memory becomes too low and then high enough again.
Changed Timeline > Detach Audio to automatically create a group.
Changed the Jobs log viewer to automatically and scroll to the end if it is left open while a job is running.
Changed the Slideshow Generator to remember all options.
Changed the splitter between UI panels to be easier to find and grab to drag.

New Version 23.12: Fight the Good Fight

Fri, 15 Dec 2023 00:00:00 -0800

Version 23.12.15 is now available for DOWNLOAD!

This is release is a small collection of fixes and upgrades.

Fixed crash on start on Wayland on Ubuntu 22.04 and 23.10 - may require installing qt6-wayland (broke in v23.11).
This breaks support for Wayland on Ubuntu 23.04, which is a less important version than the other two. The combination of Wayland and Qt 6 seems impossible to handle universally in the portable/AppImage/Snap binary bundle. If installing a Qt 6 Wayland package does not work in your distro, some options are to login using an X session instead of Wayland or try the Flatpak.
Fixed numerous audio filters missing on macOS/Intel (broke in v23.11).
Fixed crash in No Sync video filter with new Ease Back and Ease Elastic keyframes.
Fixed Equalizer: Parametric > Preset not loading (broke in v23.09).
Fixed Slideshow Generator not padding videos on mismatching aspect ratio (broke in v23.09).
Fixed Timeline waveform is not updated when changing Properties > Audio > Track.
Fixed #filename# and #basename# keywords in Text: Simple video filter with non-ASCII filenames on Windows.
Fixed Properties > View Bitrate opens too big on high DPI screen.
Fixed Properties > View Bitrate > Save image is not anti-aliased.
Fixed Properties > Measure Video Quality accuracy when Color range is Full.
Fixed some minor memory leaks.
Changed all NVENC hardware encoders in Export to use CQ instead of constant QP for VBR rate control.
Ugraded FFmpeg to version 6.1
Upgraded AV1 decoder dav1d to version 1.3.0 and AV1 encoder libaom-av1 to version 3.8.0
Upgraded rubberband audio pitch library to version 3.3.0

New Version 23.11: Easing for Keyframes

Wed, 29 Nov 2023 00:00:00 -0800

Version 23.11.29 is now available for DOWNLOAD!

This highlight of this version is the addition of easing for keyframes: ease in, ease out, and ease in/out with different levels of acceleration and tricks like elastic and bounce. See the Easing Functions Cheat Sheet web page for an animated graphical overview of these behavior options.

Improvements

Added Crop:Rectangle > Apply to Source button. This button is only enabled when the aspect ratio of the source media matches your project’s Video Mode because it is impossible to include the black padding that Shotcut adds to a source. This feature is the primary way to simply “crop a video.” You do not need to use the timeline for this. You can simply:
1. set Settings > Video Mode to Automatic,
2. open a video file,
3. add the Crop: Rectangle video filter,
4. adjust the rectangle control in the player,
5. click Apply to Source in the Filters panel,
6. choose Yes in the dialog asking to change the Video Mode, and
7. Export.
Added Opacity to GPS Text, Text: Simple, and Timer filters.
Improved performance of Timeline > Zoom.
Added rectangular selection to Timeline.
Added Settings > Timeline > Rectangle Select.
This is on by default, and scrubbing with the mouse on the timeline requires clicking near the play head. When this is on, hold Shift to turn it off temporarily. When this is off, hold Shift to temporarily turn it on.
Changed the Smooth keyframe type to avoid overshoots and cusps.
This only applies to new projects made with this and future versions. Thus, the behavior of smooth keyframes made with an earlier version remains the same for compatibility reasons.
Added Ease In, Ease Out, and Ease In/Out to Keyframes.
This also changes the appearance of keyframes in the timeline view of Keyframes to make it more clear where the behavior applies - between keyframes. Remember this: when thinking about “in” or “out”, for Shotcut “in” refers to the beginning of something - a clip, filter, or parameter between keyframes. And “out” refers to the end of something. So, this is not easing into a keyframe and easing out of a keyframe. Rather, it is easing into or out of the change/segment/span/tween of a parameter between keyframes.
Added Properties > View Bitrate….
If you have ever used the classic Bitrate Viewer for Windows and frustrated with the lack of updates or not available on your current OS, here you go.
Added a Track Auto Fade Video filter. This can only be added to tracks and makes a dip to black or other color or fade in and out opacity for overlays to each clip.
Changed Export > Codec and Audio to disable some options when a lossless-only or an intra-only codec is selected.
Added Settings > Timeline > Automatically Add Tracks.
The defaults for this is off because adding tracks increases memory usage. Also, it does not automatically add a track if nothing is in the Timeline as the timeline is optional in Shotcut. Also, it does not automatically add a track when you open a project with no empty tracks. It only adds tracks when you add something to the timeline or move a clip between tracks.
Added a button in Filters to save a filter set and change the Copy checked filters button to not show a dialog.
Added Filters > Set > Glow Intensity.
This demonstrates how you can mix a filtered output with the input to reduce it. Also, change the Mask: From File > Treshold to do a side-by-side comparison with and without the filter.
Added Split at Playhead back into the timeline clip context menu.
Changed the Save option in the low memory dialog to perform a backup and save to prevent breaking projects.
Added support for av1_nvenc NVIDIA AV1 hardware encoder on Windows and Linux.
Upgraded MLT to version 7.22.0.

New Bugs

Fixed honoring the “Do not show this anymore” checkbox in the Convert to Edit-friendly dialog (configuration key showConvertClipDialog) (broke in v23.09).
Fixed the new batch convert dialog (View > Resources) appeared instead of the old Convert to Edit-friendly one when dragging a single concerning clip to Playlist or Timeline (broke in v23.09).
Fixed Motion Tracker filters are forgotten upon switching to Source player (broke in v23.09).
Fixed Mask: Simple Shape > Softness not working on macOS (broke in v23.05).
Fixed saving a favorite for Filters > + > Sets.
Fixed Timeline appears all white on Qt 6.6.
Fixed libvpx security vulnerability CVE-2023-5217.
Fixed libwebp security vulnerability CVE-2023-4863.

Old Bugs

Fixed Text: Simple > #createdate# keyword deletes preceding text.
Fixed a crash when opening View > Scopes > Audio Loudness.
Fixed marker at start of the next clip was deleted when using Timeline > Edit > Ripple Trim Clip Out.
Fixed Properties > Transition changes were lost when Undo after trimming a clip’s out point on the Timeline.
Fixed a crash when Undo after trimming a transition that resulted in a new transition. With this fix Shotcut no longer permits creating a new transition within the same mouse drag that removes a transition.
Fixed AMD (AMF) quality options in a saved Export preset shows up in the Other tab overriding Codec > Quality.
Fixed YouTube export preset is not H.264 high profile with some hardware encoders.
Fixed a memory leak when using YADIF deinterlacers.
Fixed color of export from still images when using full range and pix_fmt=yuv444p.

New Version 23.09

Fri, 29 Sep 2023 00:00:00 -0700

Version 23.09.29 is now available for DOWNLOAD!

This release has reliability and performance improvements plus some nice new things such as a batch convert tool and keyframes for color parameters.

New Bugs

Fixed crash when changing Properties > Rotation on interlaced video.
Fixed crash when changing Properties > Video > Track on video-only file.
Fixed memory leak in Load Keyframes from Motion Tracker in several video filters:
- Crop: Rectangle
- GPS Text
- Size, Position & Rotate
- Spot Remover
- Text: Rich
- Text: Simple
- Timer
Fixed Keyframes panel not working properly when moved.
Fixed some memory leaks and random crashes due to memory management.
Improved the speed of loading projects and editing.
(Existing projects must be saved after opening to upgrade them to benefit loading speed.)
Fixed keyboard behavior of Help > Actions and Shortcuts on macOS.

Old Bugs

Fixed Undo after trimming an out point on Timeline with Ripple All Tracks enabled.
Fixed H.264 Export > Use hardware encoder with Codec > Rate control > Constant Quality on macOS/ARM.
Fixed Export or turning off Settings > Proxy > Use Proxy if the file starts with a data stream such as videos recorded on Google Pixel phones, for example.
Fixed reordering when there are many filters in Filters.
Fixed Add Selected to Slideshow with Timeline > Ripple All Tracks misbehaves and should be ignored.
Fixed some usability quirks with drag-n-drop and Ctrl multiple selection in the Playist > Icons view.
Fixed Filters > + > Time is sometimes empty when player tab is Source.
Fixed timeline marker may be incorrectly deleted when Timeline > Ripple Markers is on.
Fixed unable to save export job View XML with .mlt file name.

Improvements

Changed Export > Presets > audio > FLAC to (raw) flac format instead of Matroska.
Upgraded Glaxnimate to version 0.5.4 with limited support for After Effects projects (no plugins and no video or audio media - drawing and image animations only).
New and improved installer for Windows.
Improved the speed and memory of Timeline > Append, Insert, and Overwrite.
Changed Missing Files > Search to save the directory chosen.
Added --glaxnimate command line option to launch Glaxnimate instead (handy for Linux AppImage and Flatpak).
Improved the quality of Settings > Proxy > Use Hardware Encoder on macOS.
Improved the the color dialog on GNOME.

New Version 23.07: Never Say Never

Sat, 29 Jul 2023 00:00:00 -0700

Version 23.07.29 is now available for DOWNLOAD!

This release has important bug fixes plus new audio filters to remedy an old problem.

New Bugs

Fixed crash on startup on older Windows 10 computers that do not have Direct3D 11 (broke in v23.05).
Fixed Timeline scrubbing and skimming accelerate too much (broke in v23.06).
Fixed Stabilize analysis jobs not working on a speed-adjusted timeline clip (broke in v23.05).
Fixed the visibility of the cursor in the Text: Rich filter’s editor (broke in v23.05).
Fixed the up and down cursor keys not working in some numeric fields (broke in v23.05).
Fixed seeking on the new Speed: Forward Only and Speed: Forward & Reverse filters.
Fixed the buttons in the Delete Filter Set confirm dialog are hidden if the name is long.
Fixed the color level of RGB and RGBA sources (e.g. images) with GPU Effects.
Fixed crash adding a GPU filter to Timeline > Output by not showing GPU filters for that selection.

Old Bugs

Fixed shift-drag-drop from Windows Explorer to Playlist deletes the files! This is an old bug, and Shotcut is not deleting the files. But it accepts a move drop action for the purpose of reordering playlist items. However, doing so with a list of filenames makes Windows assume the receiving application did something appropriate with thes file and then… delete them on behalf of the app just to be sure?!? Smooth move. (Another Windows file manager Directory Opus does not exhibit this bad behavior.)
Fixed another very old bug on Windows where sound does not follow the default output device, for example plugging headphones, until you restart the app. Please note that if you are using Settings > Audio Channels > 6 (5.1) after the default sound output changes, you will likely experience distortion in the audio playback until you restart the app.
Added the --SDL_AUDIODRIVER command line option for Windows and Linux.
Fixed appending to Playlist from clipboard with nothing yet opened in the Source player.
Fixed the Export > Audio > Quality range for the aac codec.
Fixed trying to drag a keyframe vertically may snap changing its horizontal position.
Fixed clicking OK in a color dialog on Windows without changing anything resets the alpha to 255.
Fixed top-field-first interlaced output.

Improvements

Added Track Auto Fade and Track Seam audio filters. These filters address an old problem where clicks and pops may be heard in export when switching between clips due to discontinuities in the audio stream. A recommended technique was to add a 2 frame Fade Audio Out and Fade Audio in filters on clips. Track Auto Fade automates that. Track Seam works on a similar level but rather attempts to do a smoothing between outgoing and incoming samples around edit points. Both of these new filters may ONLY be added to individual tracks—audio or video.
Added Transition type > Cut to the Slideshow Generator.
Added Ctrl+Wheel (command on macOS) to numeric fields to increment and decrement by a larger amount.
Updated Qt libraries to version 6.4.3.
Updated libebur128 to version 1.2.6.
Updated rubberband library to version 3.2.1.
Updated MLT to version 7.18.0.

New Version 23.06

Wed, 14 Jun 2023 00:00:00 -0700

Version 23.06.14 is now available for DOWNLOAD!

This release is mainly a collection of desirable bug fixes.

New Bugs

Fixed H.264 output when using Export > Use hardware encoder with NVIDIA (h264_nvenc). (Note: please avoid changing Codec > B frames higher than 0.)
Fixed file dialogs in filters crash Shotcut in Linux AppImage or on KDE.
Fixed crash in Text: Rich > File > Open when choosing a text file.
Fixed crash changing Video Mode with Count generator with GPU Effects on.
Fixed crash when trying to Open MLT XML as Clip (nest project) with GPU Effects on.
Fixed loading JPEG images over 32 megapixels.
Fixed player not working if Settings > Player > External Monitor was used in a previous version.
Fixed Timeline > Replace on a clip breaks some of its video filters.
Fixed Keyframes > Add Keyframe in the Mask: Simple Shape filter.
Fixed changing Keyframe Type or a keyframe’s time position in the Mask: Simple Shape filter.

Old Bugs

Fixed custom keyboard shortcuts for actions in the Timeline or Keyframes context (right-click) menu.
Fixed Properties > Copy Fill File Path uses incorrect directory separator on Windows.
Fixed chroma bleeding on some (e.g. Ut Video) interlaced 4:2:0 files.

Improvements

Improved the smoothness of fast forward (up to 64x) playback.
Improved Timeline performance and automatic scrolling.

Release 23.05 Updated to 23.05.14

Sun, 14 May 2023 00:00:00 -0700

The latest release 23.05 has been updated to a new version 23.05.14 to restore Settings > Theme and fix several major new bugs.

New Version 23.05

Sun, 07 May 2023 00:00:00 -0700

Version 23.05.14 is now available for DOWNLOAD!

Qt 6

Qt is the main UI and app library (separate from the media engine) that Shotcut uses. This is the first major upgrade of it since Shotcut started over 10 years ago with Qt 5! (Some interim upgrades did feel major tho.) It was a lot of work, but as a result:

The Windows version now directly uses Direct3D 11 instead of OpenGL (or OpenGL converted to Direct3D) for drawing portions of the UI: Timeline, Keyframes, Filters, and the video player. This is faster, and we hope it improves compatibility.
The Windows version improves support for fractional display scaling in the system settings (e.g. 125% or 150%).
The macOS version now directly uses Metal (Apple’s GPU tech) instead of OpenGL for drawing portions of the UI (see above). It is faster.
The macOS app is now universal: compatible with both Intel and Apple Silicon CPUs (M1/M2) in the same app.
Some fixes for commonly reported Linux bugs like some images not rendering, visual controls not showing, and OpenSSL 3 compatibility. This also ought to improve things on Wayland.
There is now an ARM64 build of the Flatpak for Linux (but none of the core developers currently has a Linux/ARM system for testing and support).

Performance Improvements

Besides the performance improvements from Qt 6 above:

Some timeline optimization.
Additional multi-threading in audio/video file reading.
Faster preview for most video clips without filters.

GPU Effects

Settings > GPU Effects is back! We made several big fixes to improve its stability. Decoupling it from the OpenGL used for the UI and video display also helps. If you think its performance is not so great try it with Preview Scaling. GPU effects’ performance improvement mainly comes on systems with weak CPUs, with certain filters like Scale & Position, and when stacking filters and video tracks. It also works best when using only GPU filters.

GPU effects is not just about performance but also quality since it does all processing in linear color, which gives optimally colored blending and interpolation.
End-to-end support for 10-bit! For this to work, on 10-bit sources use only GPU filters. Nothing prevents you from adding CPU filters, but that will introduce an 8-bit down- and up-conversion into the pipeline. To add text, use a text clip using Open Other > Text as that is not a 10-bit video source.
Searching in Filters on “gpu” shows only/all GPU filters.
All previous limitations are removed and working now: text filters, video scopes, stabilization.
The Blend Mode video filter and track Properties option is not available because it is not yet implemented.
Rotation is not available in the Size & Position filter because that is not implemented yet.

Motion Tracker Video Filter

Added a Motion Tracker video filter. This is required to use motion tracking. It only does the preview and analysis and is not intended to include effects but rather drive other video filters…
Added a Load Keyframes from Motion Tracker button to the following filters:
- Corner Pin
- Crop: Rectangle
- GPS Text
- Mask: Simple Shape
- Size, Position & Rotate
- Size & Position (GPU)
- Spot Remover
- Text: Rich
- Text: Simple
- Timer
The Motion Tracker can be on a different clip than the clip with the above filters.
The dialog only shows Motion Trackers that have successfully completed analysis.
Click Reset in the dialog to remove the keyframes added by motion tracker and restore the state of these parameters to before motion tracking.
Clicking Apply in the dialog more than once automatically resets the affected parameters before adding new keyframes; so, you do not need to reset manually between changes.
You can edit the added keyframes, but if you reapply the motion tracker your changes are discarded.
To change the initial position of something after applying tracking you should Reset, make changes, and then Apply again.
Disable the Motion Tracker when your changes and its analysis are done (or turn off its preview). I do not recommend removing this filter when you are done loading keyframes because if you need to make an adjustment, this filter must still be available to list it in the dialog and get its tracking data.

More New Features!

Added new time filters: Speed: Forward Only and Speed: Forward & Reverse. These are usually friendlier to use than Time Remap. The forward only version does not usually require converting the clip first unlike Time Remap and Speed: Forward & Reverse.

Added saving and loading filter sets. A filter set is a collection of filters. The copy and paste buttons in the Filters panel open new Copy Filters and Paste Filters dialogs. When copying filters, you can optionally give it a name, in which case it will be saved to use not only in the current project but also all projects and sessions. Giving it a name still also puts it on the system clipboard. When pasting filters, you can choose to paste from the clipboard or a saved filter set. A few examples are included: Obscure With Blur, Obscure With Mosaic, Text Simple with Gradient Back.

Added an Add To Timeline button to many things in the Open Other menu/dialog. That usually saves a couple of steps.

Added a visual rectangle control to the Mask: Simple Shape filter.
Holding Shift while dragging a point in the Corner Pin filter moves all corners together.
Added faster and better quality YADIF deinterlacer plus addition of BWDIF deinterlacer.
Added 10-bit export presets under the “ten_bit” category.
Added support for Intel (“qsv”) AV1 and VP9 hardware encoders on Windows including 10-bit for AV1.

Fixes and General Improvements

Less audio crackling in exports when audio source is not 48000 Hz sample rate.
Less audio crackling upon start of playback in preview.
Upgraded Glaxnimate to version 0.5.3, which fixes some bugs and can animate motion along a drawn path.
Upgraded FFmpeg to latest version 6.
Upgraded MLT to latest version 7.16.0.
Upgrade AV1 codecs to latest versions.
Stabilize and Normalize: Two Pass on a timeline clip is faster.
The Lens Correction video filter is back.
Added Settings > Language > Hebrew.
Open Other > Text now has a Rich option.
Changed File > Export > Video and its shortcut to be the same as clicking Export > Export File.
Fixed seeking on raw FLAC audio files.
Fixed Record Audio breaks the state of the player’s mute toggle when you unmute the Shotcut audio during recording.
Fixed using the mouse wheel to scroll the timeline horizontally on macOS and Linux.
Fixed image padding not transparent during a transition.
Added low disk space warnings to the Properties > Convert and Reverse actions.
Fixed loading projects made with version before 19.06 using comma for decimal symbol.
Fixed chroma bleeding for interlaced YUV 4:2:0 video sources.
Fixed Shotcut became very slow if something wrong and very large was saved to Recent. Shotcut no longer saves recent file names to the main configuration file, which is the Registry on Windows. It now saves to a recent.ini text file in its app data directory and limits the maximum size of any entry.

Drawbacks and Limitations

Settings > Player > External Monitor with a system monitor (not Blackmagic peripheral) is no longer available.
Export progress no longer shows on the Windows taskbar icon.
The minimum version for Windows is now Windows 10. Older systems can continue to use version 22.12.
The minimum version of our non-Flatpak Linux binaries is now based on Ubuntu 20.04 LTS, which uses glibc 2.31. This is due to modern C++ requirements in dependencies, and bundling libstdc++ can break non-bundled system components. Previously, it was based on Ubuntu 18.04 LTS, whose support period ended in April, 2023. Older systems can continue to use version 22.12, or maybe the Flatpak will work.

GPU Effects

Settings > GPU Effects is back! We made several big fixes to improve its stability. Decoupling it from the OpenGL used for the UI and video display also helps. This is being made for testing purposes to get feedback before deciding whether to leave it on in the April release. If you think its performance is not so great try it with Preview Scaling. GPU effects’ performance improvement mainly comes on systems with weak CPUs, with certain filters like Scale & Position, and when stacking filters and video tracks. It also works best when using only GPU filters.

GPU effects is not just about performance but also quality since it does all processing in linear color, which gives optimally colored blending and interpolation.

Added saving and loading filter sets. A filter set is a collection of filters. The copy and paste buttons in the Filters panel open new Copy Filters and Paste Filters dialogs. When copying filters, you can optionally give it a name, in which case it will be saved to use not only in the current project but also all projects and sessions. Giving it a name still also puts it on the system clipboard. When pasting filters, you can choose to paste from the clipboard or a saved filter set. A few examples are included: Obscure With Blur, Obscure With Mosaic, Text Simple with Gradient Back.
Added an Add To Timeline button to many things in the Open Other menu/dialog. That usually saves a couple of steps.
Added a visual rectangle control to the Mask: Simple Shape filter.
Holding Shift while dragging a point in the Corner Pin filter moves all corners together.
Added faster and better quality YADIF deinterlacer plus addition of BWDIF deinterlacer.
Added 10-bit export presets under the “ten_bit” category.
Added support for Intel (“qsv”) AV1 and VP9 hardware encoders on Windows including 10-bit for AV1.

Fixes and General Improvements

Less audio crackling when audio source is not 48000 Hz sample rate.
Less audio crackling upon start of playback in preview.
Upgraded FFmpeg to latest version 6.
Upgraded Glaxnimate to version 0.5.3, which fixes some bugs and can animate motion along a drawn path.
Stabilize and Normalize: Two Pass on a timeline clip is faster.
The Lens Correction video filter is back.
Added Settings > Language > Hebrew.
Open Other > Text now has a Rich option.
Changed File > Export > Video and its shortcut to be the same as clicking Export > Export File.
Fixed seeking on raw FLAC audio files.
Fixed Record Audio breaks the state of the player’s mute toggle when you unmute the Shotcut audio during recording.
Fixed using the mouse wheel to scroll the timeline horizontally on macOS and Linux.
Fixed image padding not transparent during a transition.
Added low disk space warnings to the Properties > Convert and Reverse actions.
Fixed loading projects made with version before 19.06 using comma for decimal symbol.
Fixed Shotcut’s sound on Windows not following the output device when it changes.
Many other smaller things not mentioned here - see Git history.

Drawbacks and Limitations

Settings > Theme is gone due to a bug or limitation in Qt 6 Quick Controls. The Shotcut dark or light theme now strictly follows the system settings. On Linux, that is hit-or-miss depending on the desktop environment and its version (and, sadly, not the AppImage). For many people this will not make a difference. For many others, it might make you want to switch your system to dark mode. I do not expect this situation to change in the near future (2023). Yeah, I am not real happy about it either, but it is what it is - which means all comments, forum posts, and bug reports about this will be ignored, hidden, or closed.
Settings > Player > External Monitor with a system monitor (not Blackmagic peripheral) is no longer available.
Export progress no longer shows on the Windows taskbar icon.
The minimum version for Windows is now Windows 10. Older systems can continue to use version 22.12.
The minimum version of our non-Flatpak Linux binaries is now based on Ubuntu 20.04 LTS, which uses glibc 2.31. This is due to modern C++ requirements in dependencies, and bundling libstdc++ can break non-bundled system components. Previously, it was based on Ubuntu 18.04 LTS, whose support period ends in April, 2023. Older systems can continue to use version 22.12, or maybe the Flatpak will work.

Alpha Version 23.03

Fri, 03 Mar 2023 00:00:00 -0800

Get the alpha version 23.03.03 HERE

Alpha

Alpha here means that it is not feature complete, but there are many exciting changes that we want people to try out and provide feedback. If it eats your homework, do not complain. It is just for toying around and testing. There will be a beta version around the end of March or early April to add or complete more features. The final release is planned for the end of April.

Qt 6

The Windows version now directly uses Direct3D 11 instead of OpenGL (or OpenGL converted to Direct3D) for drawing portions of the UI: Timeline, Keyframes, Filters, and the video player. This is faster, and we hope it improves compatibility.
The Windows version improves support for fractional display scaling in the system settings (e.g. 125% or 150%).
The macOS version now directly uses Metal (Apple’s GPU tech) instead of OpenGL for drawing portions of the UI (see above). It is faster.
The macOS app is now universal: compatible with both Intel and Apple Silicon CPUs (M1/M2) in the same app.
Some fixes for commonly reported Linux bugs like some images not rendering, visual controls not showing, and OpenSSL 3 compatibility. This also ought to improve things on Wayland.
There is now an ARM64 build of the Flatpak for Linux (but none of the core developers currently has a Linux/ARM system for testing and support).

Performance Improvements

Besides the performance improvements from Qt 6 above:

Some timeline optimization.
Additional multi-threading in audio/video file reading.

GPU Effects

Settings > GPU Effects is back! We made several big fixes to improve its stability. Decoupling it from the OpenGL used for the UI and video display also helps. This is being made for testing purposes to get feedback before deciding whether to leave it on in the April release. If you think its performance is not so great try it out with Preview Scaling. It works good with that, and that helps. GPU effects’ performance improvement mainly comes on systems with weak CPUs, with certain filters like Scale and Position, and when stacking filters and video tracks. It also works best when using only GPU filters.

Searching in Filters on “gpu” shows only/all GPU filters.
All previous limitations are removed and working now: text filters, video scopes, stabilization.
GPU effects is not just about performance but also quality since it does all processing in linear color, which gives optimally colored blending and interpolation.
The Blend Mode video filter and track Properties option is not available because it is not yet implemented.

Motion Tracker Filter

This is currenty just a toy filter with plans to apply the analysis results to other filters in the beta. For now, you can choose a region to track with a visual rectangle control and see that it is working. You can preview the tracking and run analysis to improve playback/export performance. When released, this filter will not do any rendering itself outside of the preview. It is intended to cooperate with many other filters. It is included in the alpha to test out the new build components and offer a sneak peak of this new feature.

Fixes and General Improvements

Less audio crackling when audio source is not 48000 Hz sample rate.
Upgraded Glaxnimate to version 0.5.2, which fixes some bugs and can animate motion along a drawn path.

New Version 22.09: Action Search & Editable Shortcuts

Fri, 23 Sep 2022 00:00:00 -0700

Version 22.09.23 is now available for DOWNLOAD!

Action Search and Editable Shortcuts

This new feature provides a unified action search and shortcut editor. Action search makes it quickly to find and execute a command. It also provides a keyboard shortcut reference and lets you add or change shortcuts - all in one!

Replaces the old Keyboard Shortcuts… item in the Help menu and takes its keyboard shortcut ?.
/ is also a default shortcut, and either shortcut can be changed.
Searches both action name and shortcut.
Press Return/Enter within the search box to move focus to the list of actions.
Press Return/Enter on a selected Action to trigger it and close the dialog.
Shift, Ctrl, or Alt + Return/Enter on a selected action to trigger it and NOT close the dialog.
Double-click an action to trigger it but NOT close the dialog.
The dialog is not modal so you can leave it open and to the side while working.
Press Esc when the dialog has focus to close it.
Press F2 when an action is selected to edit its first shortcut.
Single-click a selected shortcut to enter edit mouse using the mouse. This means you typically need two single clicks: one to select, the second to enter into edit mode.
You can Tab out of edit mode to navigate focus to the apply button and press Space to trigger the apply. It is intentional that you cannot assign Tab as a keyboard shortcut to an action.
There are some keyboard buttons such as J/K/L that are reserved and cannot be used in a shortcut. You will see an error message when you try to apply it.
You can define up to 2 shortcuts per action! You may want to leave the default as well as add your preferred shortcut.
A big portion of the UI had to be rewritten to support this. As a result:
- All panel (hamburger) menus are consistently on the left/first.
- Panel-specific Options sub-menus were moved to Settings main menu.
- The keyboard shortcut to switch the player between Source and Project is now P.
- The default shortcuts to change the current track now require Ctrl+Alt in addition to cursor up and down.
- Various hidden or under-exposed actions now have a menu item somewhere including a new Player main menu.
- Many translations will be lost.

Transition Preview and Improved Custom Transitions

There is a folder now in the App Data Directory named transitions where you can store these.
All files in the transitions folder are listed in transition Properties, the Mask: From File video filter, and the Slideshow Generator dialog.
Added a favorite button in transition Properties and Mask: From File that copies your chosen custom file to the transitions folder.
Added a quick preview to transition properties.
Added a link to our Resources web page where you can download custom transitions in Properties.

Filter Keywords and Icons

We improved the Filters add-filter chooser.

Added translatable keywords to facilitate search. For example, “transform” shows Size, Position & Rotate.
Added the English filter name in an un-translataed manner to the keywords so people using a translation can more more easily find things based on proliferic English advice.
Added animated icons to most filters to demonstrate what they do.

GPS Graphic Video Filter

The new GPS Graphic video filter draws GPS data-driven graphs, paths, and speedometers.

Also, we added the gopro2gpx utility to let you export a GPX file from a GoPro videe using Properties > menu > Export GPX. This saves the .gpx in the same folder as the video file with the same name but different exension. Then, you open this file with the GPS Graphic or GPS Text filters.

More New Stuff

Added limited support for reading WebP Animation.
Added Fisheye video filter (see its presets).
Added snapping to the playhead to Keyframes.
Added the ability to drag-scroll/pan using the middle mouse button (press mouse wheel) to Timeline, Keyframes, and the player when zoomed in.
Added the alpha Operation, Reverse, and Invert parameters to the Mask: Draw video filter.
Added Settings > Reset… to reset all settings including hidden ones.

Fixes

Fixed Move Track Up or Move Track Down breaks the order of blending/compositing.
Fixed opening files with a % in their path or name.
Fixed sometimes a date does not appear in Playlist.
Fixed Old Film: Scratches video filter not working (broke in version 22.04).
Fixed Stabilize video filter uses invalid analysis data after pasted.
Fixed File > Open MLT XML as Clip… changes the current Video Mode.
Fixed audio artifacts introduced after splitting a clip that has been converted or reversed using the better/large/DNxHR option.
Fixed Text: Rich filter’s toolbar may not reflect the current text color.

Changes

Show audio-clips without album art as a checkboard for transparent instead of white.
Deprecate and hide the Lens Correction video filter since it is low quality (no interpolation) and now there is Fisheye.
Upgraded FFmpeg to v5.1.0
Upgraded dav1d AV1 decoder v1.0
Upgraded AOM AV1 encoder to v3.4.0
Upgraded libvpx VP8/9 encoder to v1.12.0

New Version 21.05.01: Time Remap

Sun, 02 May 2021 00:00:00 -0700

Version 21.05.01 is now available for DOWNLOAD!

WARNING

Time Remap and Speed Ramping!

Usage requires knowledge of how to use Keyframes. Basic, quick-start usage is Filters > Time > Time Remap > Keyframes. Go to this forum post for more usage information.

If you try to use it on a video clip with B-frames (a video encoding technology) Shotcut will show the Convert to Edit-friendly… dialog.
This filter cannot be disabled.
This filter does not support simple keyframes or filter trimming.
This filter can not be applied to tracks or the timeline output.
Disabled Smooth keyframes for Time Remap to prevent unexpected direction changes.

Apple Silicon (M1) a.k.a. ARM64

We now have a native (not using Rosetta 2) build working on Apple M1 devices! This is not yet a universal app, maybe later in the year for that. This build does not support JACK Audio. Get shotcut-macos-ARM64-210501.dmg.

New

Added a new filter Time Remap in the new Time category that affects both audio and video.
Added an Apple Silicon build.
Added an option to Ignore missing files in Export > Export File (blocking dialog added in v21.01).

Added a button in the Keyframes parameter track header to vertically zoom in to the minimum and maximumn values.
Added a Use Sub-clip checkbox to the Convert to Edit-friendly dialog, under Advanced. This will convert only the trimmed portion of a clip plus up to 15 seconds before the in point and after the out point for a timeline clip. When this is on, only the selected clip is replaced and not every clip based on the same source. This option is especially convenient for use with Time Remap in which case it defaults to on if the clip has been trimmed.
Added a Keep Advanced open checkbox to the Convert to Edit-friendly dialog that remembers your choice between sessions.
Added a status message tip about useful keyboard modifiers to use when dragging keyframes.
Added the display of minimum, maximum, and midpoint values to the vertical axis of curved parameters in Keyframes.

New Version 20.09.13: Pad Blur and Rich Text Video Filters

Sun, 13 Sep 2020 00:00:00 -0700

Version 20.09.13 is now available for DOWNLOAD!

Security Notice

All users are encouraged to upgrade to address a security vulnerability (CVE-2020-24619) in Shotcut’s check for a new version. In previous versions it was not using a secure network connection making it is possible for an attacker to change the URL to the web page containing the release notes and download link. That has been fixed in this version.

HTML5 Deprecation

Shotcut’s HTML5-based filters – including non-obvious video filters such as Crop: Rectangle in previous versions – were based on an old technology (QtWebKit) that we decided to remove. The technology is no longer officially supported by its founding organization and hinders our ability to upgrade more important technology. Moreover, there were some lingering stability bugs related to its integration that are very difficult to fix. In the previous version, some filters were marked as “DEPRECATED” as a result of this decision, namely Text: HTML, but not Crop: Rectangle, Crop: Circle, and Choppy. These were rewritten for this version. This new version automatically converts the Choppy, Crop: Circle, and Crop: Rectangle video filters in an existing project to their new replacements. Also, we added a new video filter named Text: Rich. It is not as capable as the old Text: HTML, but it should be easier to use and manage while being more reliable. The deprecated HTML-based filters are still included in this version, but now they are hidden. They will appear only when loading old projects that include them. This provides a transition to the next version that actually removes these filters: You can load an old project using the deprecated filters and replace or remove them.

New

Blur: Pad Video Filter

This is a new useful alternative to cropping to remove black bars from images or videos whose aspect ratio does not match the project. It is available in the slideshow generator as Pad Blur.

Text: Rich Video Filter

The rich text editor writes directly on the video preview, has a floating toolbar, and saves itself into the project file with no external HTML files to manage.

New Stock Layouts with Quick Switcher

Replaced View > Layout > Timeline Project with new, better Logging, Editing, FX, Color, Audio, and Player stock (pre-defined) layouts.
The current layout is saved automatically for each stock layout if selected, and Restore Default Layout is different for each stock layout.
Added a workspace layout switcher to the main toolbar for the new stock workspace layouts. Shotcut has had a named layout system and switching in the View menu for a while now, but the stock layouts were lacking imagination. Taking inspiration from some other tools, we add new ones

Other New Things

Added Zoom to fit icons to the Timeline and Keyframes toolbars. Thanks to @Namna for this contribution.
Added a VUI to the 360: Transform video filter to adjust parameters by dragging inside the player.
Added Set Equirectangular Projection… to the Jobs menu for a successful export job. This is used to add metadata to a video file to indicate it is 360॰ video in the equirectangular projection as required by most players and web services. We thank Varol Okan for the code we used to add this.

Changes

Improved the performance of the Timeline especially with projects over one hour long.
Changed Size and Position to Size, Position & Rotate and made Rotate and Scale hidden (only appears in old projects).
Replaced Choppy, Crop: Circle, and Crop: Rectangle filters with new versions that do not use HTML through WebVfx, which was deprecated in version 20.06.28.
Changed the Rutt-Etra-Izer, Swirl, and Text: 3D filters to be hidden since they are deprecated (still loads in old projects).
Changed the video track hidden icon on the System theme to be more clear and obvious.
Show an error dialog on startup if the frei0r plugins are not installed (only affects Linux distribution packages).
Changed the keyboard shortcut 0 to zoom timeline to fit.
Changed the keyboard shortcut Alt+0 to zoom playlist to fit.
Changed the Timeline and Keyframes time ruler interval to 1 second when zoomed in.
Upgraded FFmpeg to version 4.3.1.

Fixes

Fixed using a secure connection to get the upgrade URL.
Fixed a rounding error for Color Grading video filter.
Fixed a crash and incorrect preview scaling with more than one Rotate and Scale or Size and Position filter.
Fixed colors when using an alpha/VP8 or alpha/VP9 export preset.

New Version 20.04.12: Speed Pitch Compensation and Replace

Sun, 12 Apr 2020 00:00:00 -0700

Version 20.04.12 is now available for DOWNLOAD!

The proxy management feature is not ready, but we worked on a building block in the form a Replace edit command that is integrated into Reverse and Convert to Edit-friendly. This will be used to asynchronously integrate proxies after they have been generated.

New

Added a Replace command to Timeline clip menu including blank regions with shortcut R.
Properties > Reverse now automatically replaces a selected clip on the timeline (or in Source player if using that).
Added 15 second handles when using Properties > Reverse on a timeline clip. Handles are extra footage before the in point or after the out point. This makes it easier to adjust edits or add transitions around reversed clips.
Added Properties > Duration > Timeline to show (not editable) the duration of a timeline clip.
Added a Corner Pin video filter (thanks to @sauron in the forum for the initial effort).

Added a Properties > Convert button to make Convert to Edit-friendly in the menu more convenient (kept in the menu for now because a number of support tips reference it).
Properties > Convert now automatically replaces respective clips in Source and Timeline and adds its clip to the Playlist.

Fixes

Fixed = in Text: Simple filter ignores all text before the sign (broken in v20.02).
Fixed a crash when using some video filters with Preview Scaling and multiple video tracks:

  - Choppy
  - Crop: Circle
  - Crop: Rectangle
  - Rutt-Etra-Izer
  - Swirl
  - Text: 3D
  - Text: HTML
Fixed floating or docking some panels may crash on some Linux systems:
- Filters
- Keyframes
- Timeline
Fixed changing the name of a track in Timeline when leaving the field without pressing Enter.
Fixed File > Export Frame exports uses Preview Scaling instead of project resolution.
Fixed switching between Cut and Dissolve in transition properties.

Fixed a regression in JACK transport control (broken in v19.12).
Fixed a missing Timeline track Lock button animation when lock prevents something.
Fixed clips can be moved to locked timeline tracks (broken in v19.12).
Fixed treating paths with Windows drive letters as relative on macOS and Linux.
Fixed automatically relinking filters with HTML files (when app location changes or moving projects).

- Control
- Control+Option
- Control+Command
- Option+Command
Changed the Matrix parameter of the Dither video filter to be a drop-down combo box without keyframes support.
Changed Alpha operation > Write On Clear to Overwrite on some video filters to make them more clear:

New Version 20.02.17: Low Resolution Preview

Mon, 17 Feb 2020 00:00:00 -0800

Version 20.02.17 is now available for DOWNLOAD!

New

Low Resolution Preview Scaling

Most people’s video preview area only occupies a fraction of their screen.

Meanwhile, the app is struggling to process effects in realtime while editing a 1080p or higher video. So, it makes sense to change the processing resolution while editing to roughly the same as the preview window. For example, for many people, the video preview typically only occupies 1/9 of their 1080p screen. Thus, you can edit at 640x360 instead of 1920x1080 to give the app and computer less work.

This is now available in the Settings under Preview Scaling. If you are using a larger or high DPI screen or editing higher resolution, you might want to edit at a higher resolution, and Shotcut also offers options for 540p and 720p in addition to 360p for the preview vertical resolution.

Please remember that today there is still a processing cost to scale down the source video to the preview resolution. So, this is still not a silver-bullet, magical cure-all for performance issues. This feature will be more beneficial when low resolution proxies are used, which is planned for version 20.04 in April.

Also, please understand that preview scaling is a step further away from WYSIWYG and does not provide perfect fidelity and full precision. Some differences are unavoidable especially where blur, softness, and noise are concerned.

In addition, some filters do not support preview scaling and will process at full project resolution:

Choppy
Rutt-Etra-Izer
Stabilize
Text: HTML > Blank with Web Animations
Text: HTML > Simple Scroll
Text: HTML > Two Column Scroll

Lastly, a Use preview scaling checkbox has been added to Export > Advanced > Video. This is intended to provide a faster export for draft review. You should leave the export resolution set to the project resolution unless your preset or video codec dictates a resolution.

Audio Pitch Filter

Ever since we made it possible to change the speed of a clip, people have wanted a way to keep the audio at roughly the same pitch instead of going lower or higher. Also, sometimes people want to use a pitch effect for comical reasons or to disguise a voice. We are happy to announce a new Pitch audio filter. This has a speed compensation parameter so that you can copy the speed value from Properties into the filter. In the next version, we will directly integrate a pitch compensation option in the Properties panel. Please consider that this really only works with decent quality in the 4.0x - 0.25x speed range.

More Transitions

Frequently, people ask for more transitions. Well, how about 150+!? After you create a transition by overlapping clips on the same track, select the transition and look in Properties > Video. There has always been a Custom… option where you can upload a gray scale still image, and our Resources page provides a list of resources where to get them. In this version you can now use a grayscale video clip, which some call a “matte transition.” Forum user @jonray has put together a nice collection of these, also on the Resource page.

Please be aware that these transitions do not automatically adjust their duration. If you do not make the transition long enough, it will likely be abrupt at the end. If you make it longer, however, there is no problem. You can also use these to make multi-track transitions by adding the Mask: From File video filter to the clip on a higher video track.

Other Enhancements

Added Views > Scopes > Video Vector.
Note that the graticule on this is non-traditional, inspired by Alexis Van Hurkman.
Added the ability to rename clips in Properties by clicking into the header where the name is displayed.
Added a few more export presets:
- audio/ALAC
- audio/FLAC
- intermediate/DNxHR HQ
- intermediate/ProRes HQ
- intermediate/ProRes was changed to ProRes 422
Added Arabic translation.

Fixes

Fixed dropping multiple files to Playlist in a new project (broken in v19.12.31).
Fixed some broken keyboard shortcuts in the Turkish translation.
Fixed Properties > Speed not working after a project file repair.
Fixed clip selection after Insert Track or Remove Track.
Fixed Playlist > Add Selected to Timeline creates corrupt clips (broken in v19.12.31).

Fixed creating a Project folder with leading or trailing spaces.
Fixed saving the length property in MLT XML as a time value independent of frame rate.
Fixed starting Text: Simple video filter with “@” shows “0”.
Fixed seeking previous & next on the first track in Keyframes where you trim a filter or use simple keyframes.
Fixed an unexpected transition is created when moving a clip rightward adjacent to the next clip in Timeline (regression in v19.12.16).
Fixed drag-n-drop from Source player to Timeline left player in an inconsistent state (broken in v19.09.14).
Fixed an inconsistent colorspace conversion when accessing a cached image.
Fixed Playlist > Copy followed by a change in Properties incorrectly changes the playlist item.
Fixed clicking on the rectangle control may change its size.
Fixed using the LUT (3D) filter with file with extended characters in its file path on Windows.
Fixed a crash when using a transition on every track at the same time.

Changes

Improved the reliability of Timeline > Select None.
Changed Timeline > Master > Properties > Frame rate to show 6 decimal digits.
Reduced the latency of scrubbing (regression in v19.12.31).
Changed the video-overlay rectangle control used in some filters to allow changing the position by dragging from anywhere inside the rectangle.
To enable this, one must first double-click the center circle to change the mode. Otherwise, you would be prevented from dragging the clip out of the Source player.
Changed the Filters panel on macOS to prevent floating to avoid a frequently reported problem of the Filters window appearing blank/black.
Changed Timeline > clip context menu > Detach Audio to not seek afterwards.
Improved mouse wheel and trackpad behavior in Timeline.
Now, you do not need to ensure the mouse pointer is over a clip, speed is reduced, and zoom keeps focal point in view. The new zoom behavior does not apply when using the option Center the Playhead in the timeline menu.
Upgraded MLT to version 6.20.0 and WebVfx to version 1.2.0.

New Version 19.12.31: Move Multiple

Tue, 31 Dec 2019 00:00:00 -0800

Version 19.12.31 (aka 19.13) is now available for DOWNLOAD!

Unfortunately, version 19.12.16 introduced a major new bug when moving clips on the Timeline with Ripple on. This version not only fixes that but also includes a highly requested feature that was a year end goal: moving multiple clips on the Timeline! In addition, two more video scopes were added: RGB Parade and RGB Waveform.

Other Changes and Fixes

Allow reducing track height to very short in Timeline and Keyframes.
Fixed crackly audio playback for some Windows users.
Fixed loading project files made before v19.06 when not using a period for a decimal point.
Fixed Lift and Ripple Delete on Timeline not reliably removing all selected.
Fixed checking Properties > Image sequence may not update duration in Playlist.
Fixed the intra-VLC and non-linear-quantizer options in the XDCAM-422 and D10 export presets.

New Version 19.12: Move Freely

Mon, 16 Dec 2019 00:00:00 -0800

Version 19.12 is now available for DOWNLOAD!

This version makes the Timeline much more flexible. Previously, you could only move a clip to a blank spot on the timeline, or the move operation would be rejected and the clip would snap back to its original location. This is no longer restricted, and you can move anywhere as if you were inserting or overwriting with a new clip. Of course, you need to be more careful now! Also, when using drag-n-drop to make a transition, previously you could not have a gap in the timeline between the two clips. Now, you can drag over a gap and overlap the clips to make the transition (but still only for neighboring clips on the same track, by design.) These two improvements were needed to support the ability to move multiple clips at once. We expect to include that in the first version of 2020. Meanwhile, there were some important fixes to get out and changes for people to adjust to.

New Version 19.08

Fri, 16 Aug 2019 00:00:00 -0700

Version 19.08 is now available for DOWNLOAD!

This version continues to rework and refine existing features in the areas of video stabilization, audio normalization, converting and reversing files, external monitoring, and most significantly: the playlist.

Playlist

Changed Playlist > Open As Clip to simply Open. This action now opens the playlist item directly in the Source player, and all changes made in Source (trim in/out), Properties, Filters, and Keyframes apply to the playlist item immediately without an explicit update.
Added Playlist > Copy that opens a copy of the playlist item in Source just like the old behavior. This is useful if you want to trim out another shot from the same source clip or create a different sub-clip with different filtering.
Changed double-click on a playlist item to Open the clip instead of Copy it.
Added keyboard shortcut Shift+C to Copy a playlist item.
Now, when you drag a clip from Playlist to Timeline the timeline shows an appropriately-size box on a track.

Filters

Fixed a performance regression (since v19.06) in the following filters: Chroma Hold, Flip, LUT 3D, Mirror, Noise: Fast, Reduce Noise: Smart Blur.
Fixed reloading the filter UI for Rutt-Etra-Izer, Text: 3D, and Text: HTML resets the filter trimming in Keyframes.
Added support for keyframes to the Lens Correction and Mosaic video filters.
Fixed Swirl when maximum = 0%
Changed the minimum values for Mosaic to 0%.
Removed the scrolling animation from the Blank Web Animations HTML template.
Fixed pasting filters changes the trim and keyframes of the existing filters.
Fixed Crop: Circle and Crop: Rectangle not clearing the canvas resulting in trails in some situations.
Fixed color incorrect when using the LUT 3D filter with some other filters following it.
Fixed reliability of the Stabilize video filter to write its results (.stab) file.
Fixed showing vidstab.trf as a missing file.
Fixed updating Stabilize and Normalize: Two Pass results to clips copied between Source, Playlist, and Timeline.
Added the ability for the Stabilize and Normalize: Two Pass filters’ analysis jobs to update pending export jobs.
Added the option to run pending Stabilize and Normalize: Two Pass filters’ analysis jobs on export. This only works for Stabilize if you are using the project folder feature. Or, if not using the project folder feature, you must click Analyze to assign a results file name, but you can stop the analysis job.

The combination of the above fixes and changes means you can now easily batch convert files while applying image stabilization and audio normalization!

Properties

Added support for interlace output to Properties > Reverse and Convert to Edit-friendly including overrides for Scan mode and field order.
Improved detection of interlaced video in some files such as Ut Video in Matroska.
Added Comments to image properties along with a menu button with: Copy Full File Path, Show in Folder, and Set Creation Time…

External Monitor

Add resolution and refresh rates to the screens in Settings > External Monitor to make them easier to differentiate.
Fixed switching between different external screens on the same GPU.
Fixed external screen not showing on correct screen in some arrangements.

Export

Changed the default video quality to 55% for the Default and YouTube presets. This aligns with the x264 default crf of 23 and produces a smaller file that most people desire for upload without significant quality loss.
Added text after Export > Advanced > Codec > Quality to show the generated codec-specific quality level (e.g. crf for x264).
Fixed Stream broken by check for writable file.

Other

Fixed double-click in Recent Projects loading twice.
Fixed disabling meters in the Audio Loudness scope not shrinking space.
Added version metadata to the AppImage for Linux.
Added md5sums.txt and sha256sums.txt to the GitHub releases page.
Added saving Timeline track height to configuration, not only a project file.
Fixed trimming an unselected clip in Timeline does not correctly adjust its filters.
Changed Settings > Interpolation > Nearest Neighbor to no longer relax seek accuracy. Instead, seek accuracy is now relaxed only during trick playback (reverse, rewind, fast forward).
Added a Korean translation.

New Version 19.07

Mon, 15 Jul 2019 00:00:00 -0700

Fixed Blur: Gaussian filter makes bottom 3 rows of the image with black or garbage.
Fixed help text in the New Project view may be truncated without scroll bar.
Fixed Crop: Circle > Radius = 100% not completely extended.
Fixed loading image sequences that do not put leading zeroes into their number (bug introduced in v19.06).

New Version 19.06

Sat, 15 Jun 2019 00:00:00 -0700

Version 19.06 is now available for DOWNLOAD!

Changes and Improvements

Project Files

This version makes a big change to the way project files are saved. Now, they always save numeric values using a period for the decimal point regardless of your OS locale (region/language) setting. This makes it possible to collaborate with others that have a different decimal point setting without going through a (probably incomplete) repair process. This should also help to avoid bugs. This change applies to new projects only; old projects load and run same as before including saving. However, be aware that if your locale does not use a period for the decimal point, then older versions of Shotcut will try to repair a project created with this version because the older versions do not have this new capability.

Timeline and Keyframes Rulers

We changed the Timeline and Keyframes rulers interval to 5 seconds and show only HH:MM:SS and no frame units. This makes them cleaner and quicker to read.

Reorganized Some Video Filters

Renamed video filter Circular Frame to Crop: Circle.
Renamed video filter Crop to Crop: Source.
Renamed video filter Text to Text: Simple.
Renamed video filter 3D Text to Text: 3D.
Renamed video filter Overlay HTML to Text: HTML.
Renamed video filter Blur to Blur: Box.
Renamed Reduce Noise video filter to Reduce Noise: Smart Blur.

Other Changes

Changed Export > From to show Source instead of base file name.
Changed the default for Settings > Display Method back to DirectX on Windows.
Changed maximum duration of Color, Text, and Color Bars clips to 4 hours.
Increased maximum value of the Timer filter’s Start Delay, Duration, and Offset parameters to 24 hours.
Improved Export Job progress and estimated time remaining.

New Features

Blur Filters

In the previous versions of Shotcut the Blur video filter could create dark edges on the image. Therefore, 3 new blur filters were added that do not have this problem:

Blur: Exponential (fast)
Blur: Low Pass (fast)
Blur: Gaussian (slow)

However, they do not support Keyframes or support blurring in only a horizontal or vertical direction. So, the existing blur filter was retained but renamed Blur: Box.

The previous version changed the appearance of the toolbar to address a high density (DPI) issue on Linux. However, that made the icons larger for most people. Also, some people would simply hide the main toolbar since it took up so much space. Now, there are two new options in the View menu:

Show Text Under Icons (default on)
Show Small Icons (default off)

Additionally:

Added Jobs to the main toolbar.
Reordered panel buttons on main toolbar to match View menu.

Alpha Channel Support for HTML-based Filters

Shotcut can use HTML technologies for video effects, but previously it was limited at support the existing image or video’s alpha channel (transparency mask) and would always overwrite it with its own alpha channel, which often times was opaque. For example, this prevented maintaining transparency when using 3D text on a transparent color clip. Now, it supports the alpha channel. Using this, we have new Crop video filters.

Crop Filters

Previous versions of Shotcut’s Crop filter did not behave as some expected because it removes pixels from the edges of the source and thus changes its aspect ratio. Still, it can be useful when working with sources with a higher resolution than the project because it does not require one to crop and then upscale to remove black bars. Therefore, the existing crop filter was renamed to Crop: Source, and two new crop filters were added using HTML.

Crop: Circle
Crop: Rectangle

These two new crop filters can use the HTML alpha channel support by changing the alpha component of their Color parameter. This is very useful when using Crop: Rectangle or Crop: Circle while compositing video tracks.

More New Things

Added Ripple All button to Timeline toolbar.
Added a vertical Flip video filter.
Added Reduce Noise: HQDN3D video filter.
Added Noise: Fast video filter.
Added Noise: Keyframes video filter.
Added Add Keyframe button in Keyframes (only on parameters that show a curve UI).
Added keyboard shortcuts Ctrl+0-9 to toggle the panels.
Added Alt 0/+/- shortcuts to adjust the zoom in Keyframes.
Added Swedish translation.

Fixes

Fixed deleting the project file if there was a save error.
Fixed reliability of Settings > Display Method > Software on Windows.
Fixed Crop: Source filter not working with Color clip.
Fixed using filters on Color Bars and other generator clips.
Fixed audio filters (Compressor, Expander, Limiter, Notch, Reverb) broken
on comma for decimal.
Fixed alpha video opaque on gaps in Timeline.
Fixed Convert to Edit-friendly and Reverse if there is no audio track.
Fixed Measure Video Quality broken.
Fixed Alpha: Adjust > Invert checkbox on reload.

Removed the buggy Merge with next clip from Timeline clip context menu.

New Version 19.02: Qt Upgrade and HTTPS

Thu, 28 Feb 2019 00:00:00 -0800

Version 19.02 is now available for DOWNLOAD!

The main announcement for this release is a major update to an important library that Shotcut uses for the UI (user interface) called Qt. There have 6 major releases and two LTS (long term support) releases since the version we were using. The new version we are using is Qt 5.9.7, which is LTS (5.9) and is quite stable given the number of revisions (.7). It is a little faster as well. We did not upgrade to the latest LTS (5.12) in order to retain compatibility with macOS 10.10 and 10.11, and we want to use the same Qt version across platforms. (Linux Flatpak is an exception.) With our new Qt builds, we added support for HTTPS, which extends to our HTML effects based on WebVfx and QtWebKit. This will let custom HTML titles and effects that you make link to JavaScript libraries on the Web, which is mostly HTTPS now.

New Features

Added Offset to the Timer video filter.
Added Vertical HD 30 fps and Vertical HD 60 fps video modes.
Added support for HTTPS.
Added --QT_SCALE_FACTOR and --QT_SCREEN_SCALE_FACTORS command line options.
Added English (Great Britain) translation.

Fixes

Fixed opening image sequence on Windows with extended/special characters in file path/name.
Fixed crash on some video clips, particularly those with Google Pixel 3 and likely others.
Fixed field order with interlaced export.
Fixed an image artifact when using keyframes with the Mask: Simple Shape filter.
Fixed image and alpha channel integrity with transitions on clips with a non-opaque alpha channel.
Fixed a crash when changing clip Properties > Audio > Track.
Fixed Properties > Video > Color Range inaccurate after changing it.
Fixed Shake One Second presets in regions that use comma for decimal point.
Fixed moving a Playlist item to the end.
Fixed more dialogs to be modal to prevent them from going behind the main window.
Fixed Overlay HTML webvfx templates when using a project folder.
Fixed volume slider appears before main window at launch on macOS.

New Version 18.12: New and Improved Mask Filters

Sun, 23 Dec 2018 00:00:00 -0800

Version 18.12 is now available for DOWNLOAD!

The new Mask: Apply filter makes it possible to mask filters without using multiple tracks! Use Mask: Simple Shape or Mask: From File to start the filter mask followed the video filters to be masked followed by Mask: Apply to apply the mask to the filters in between. Filters before or after the mask filters affect the entire video frame. One can still use Mask: Simple Shape or the new Mask: From File to affect the alpha channel for multitrack compositing as before.

New Features

Added View > Scopes > Video Histogram.
Added Preset to some more filters:
- Audio Gain/Volume
- Blur
- Brightness
- Opacity
Added Preset and simple and advanced keyframes to the Balance and Pan audio filters.
Added a Levels video filter with simple and advanced keyframes!
Added Properties > Color Range for video clips.
Replace the Mask video filter with 3 new filters:
- Mask: Simple Shape
- Mask: From File
- Mask: Apply

The new Mask: From File is a powerful new video filter offering 3 modes:

wipe transition (stock or custom)
Channel > Brightness from a video or image file (File > Custom…)
Channel > Alpha from a video or image file

Moreover, Threshold can be animated with simple or keyframes, which is especially nice when used with luma-wipe image files (stock or custom). Not only can you wipe on a filter but also you can use this as an alternative way to make a wipe transition using multiple tracks (instead of same track transition).

Fixes

Fixed color accuracy of lossless/Ut Video preset and use yuv422p format.
Fixed number of digits for seconds in the Timer video filter when using Format > MM:SS.SS.

Fixed crash when undo Playlist > Remove All.
Fixed auto-saved file not removed when save and exit with no changes.
Fixed the color accuracy of the Color generator.
Fixed numeric locale bug in the Audio Spectrum Visualization and Audio Waveform Visualization filters.
Fixed clip reloaded when leaving Properties > Speed with no change.
Fixed Settings > External Monitor on Windows screen.
Fixed launch crash on Linux with (Csound) csladspa < 6.11.1 installed.

Added more library dependencies to the Linux portable tar, AppImage, and snap builds including the SWH LADSPA plugins.
The minimum macOS version has changed to 10.12.

New Release 18.09: More Better Faster

Thu, 13 Sep 2018 00:00:00 -0700

Version 18.09 is now available for DOWNLOAD!

UPDATE: Version 18.09 has been re-released (build 18.09.16) to fix major new bugs with the Rotate and Scale, Size and Position, Text, Chroma Key, Key Spill, and White Balance filters.

This release is packed with fixes and improvements in many areas!

Timeline

Added Ripple support for moving clips including Ripple All Tracks.
When Ripple is on and you move a clip to the right, it now ripples (pushes) all the clips to the right instead of making a transition (including the Ripple All Tracks option).

Added Ctrl+R keyboard shortcut to toggle Timeline Ripple,
Ctrl+Alt+R to toggle Ripple All Tracks, and
Ctrl+Shift+R to toggle both.
Improved Snapping behavior on the Timeline.
Added Ctrl+P keyboard shortcut to toggle Snapping.
Added Reset Track Height (Ctrl+0) to the Timeline menu.

Filters

Added a Timer video filter.
Added support for negative rotation to the Rotate and Scale filter.
Added Shake 1 Second - Scaled and Shake 1 Second - Unscaled presets to the Size and Position filter.

Other

Added a Text clip to the Open Other dialog.
This is a convenience item that creates a transparent Color clip with a Text filter.
Added Extract Sub-clip to Properties menu for audio/video clip.
Added Export presets for WebM VP8 and VP9 with alpha channel.

Better

Stability Fixes

Fixed a crash when quickly changing clip selections in the Timeline.
Improved closing Shotcut more reliably and the behavior of multiple shotcut processes.
Fixed Undo beyond Remove Track may crash.
Fixed a crash when moving a clip after undoing a transition.
Fixed a crash loading project after some sequence of inserting and removing tracks.
Fixed a crash loading an image with the wrong filename extension.
Fixed OS audio device changes may cause Shotcut to hang.
Fixed crash dragging simple keyframes beyond the edges of the clip.
The 32-bit Windows build can use more memory to reduce risk of crash:
3 GiB on 32-bit Windows and 4 GiB on 64-bit Windows.
Fixed a crash applying an image transform filter to an image with alpha channel (PNG, SVG).

Bug Fixes

Improved behavior of opening WebP images.
Fixed advanced keyframes for the Size and Position filter.
Fixed inserted and then hidden video tracks become audio tracks after re-opening the project.
Fixed changing Video Mode from Automatic to something else with nothing opened.
Fixed moving a transition to another track leaves a hidden clip on the old track.
Fixed trimming the out point of a timeline clip may change the in point of the following clip.
Fixed Properties > Speed, Convert, Reverse, and More Information does not work sometimes after reloading a project.
Fixed reliability of changing size and position fields with keyframes in Size and Position and Text filters.
Fixed trimming outward with Ripple All Tracks moved clips on other tracks in the wrong direction.
Fixed audio waveforms still appear on muted tracks after adding a track.
Fixed dragging clips to the Timeline stops working.

Image Fidelity

Fixed edges of text with the Text filter may get cut off (clipped).
Fixed Size and Position and Rotate and Scale filters may leave black right and bottom edge of frame.
Fixed trimming a timeline clip with Fade In/Out Video filters with “Adjust opacity instead of fade with black” enabled.
Fixed Export may change the actual frame rate and cause timing errors.
Fixed reducing the Frame/sec in Export causes timing errors in the output.
Fixed image scaling interpolation method when not using a transform filter.

Changes

Removed the Compositing toggle icon from the Timeline track head. Now, it is located in the track Properties as Blend mode with a None option.
In the 3D Text filter, replaced the Droid fonts with Liberation due to an incompatible license.

Faster

Well, to be honest, there is not much speed improvement. Most of the improvement comes from a fix to prevent an incomplete shutdown. In the case of the 32-bit Windows build, since more memory can be accessed now, we have removed some of (not all) multi-threading limits.

Improved the performance of changing filter parameters and scrubbing.
Limit the number of background thumbnail and waveform generation threads to 4.
Prevent trying to generate audio levels for waveforms for still images and other silent sources.

New Release 18.08.14

Tue, 14 Aug 2018 00:00:00 -0700

Version 18.08.14 is now available for DOWNLOAD!

Unfortunately, the previous release 18.08.11 introduced a major regression that can corrupt project files if your project has clips where you had changed Speed in Properties. If you have a project file that no longer loads, you can fix it in a simple text editor:

Open the .mlt file in a text editor (notepad.exe not recommended)
Locate every line with <property name="shotcut:comment">.
If the text that follows it on the same line before </property> is incorrect or has strange characters, remove the text between the property tags. The line should now look like
<property name="shotcut:comment"></property>.
Save the file with a new name that ends with .mlt
Try to load the repaired XML file.

New Release 18.08.11

Sat, 11 Aug 2018 00:00:00 -0700

Version 18.08.11 is now available for DOWNLOAD!

There have been enough major bugs found and fixed since the v18.08.01 release at the beginning of the month to warrant making a new release:

Fixed new crash in v18.08 changing Settings > Video Mode with nothing opened.
Fixed crash while adjusting position or size in Text and Size and Position filters.
Fixed position and size information incorrect if resolution or aspect ratio changed in Export.
Fixed Text animation (keyframes) when not the first clip in the timeline.
Fixed track name not editable after the track head had been selected at least once.
Fixed right-clicking a timeline clip breaks automatic timeline scrolling during playback.
Added Quicktime Animation Export preset to export video with alpha channel.
In Export, let option values in Other tab override values generated by other fields.

New Release 18.08.01

Wed, 01 Aug 2018 00:00:00 -0700

Version 18.08.01 is now available for DOWNLOAD!

This release primarily contains only bug fixes, which were strongly needed after a few releases with major additions and changes:

Added the timecode of failure to the Jobs panel when an export job fails (makes locating problem areas in the project easier).
Added an Unpremultiply Alpha video filter (handy to fix compositing for video clips with an alpha channel that has had its color pre-multiplied with its alpha).
Fixed various crash regressions since v18.05.
Fixed audio distortion during preview (regression in v18.07).
Fixed custom Export presets broken if name contains parentheses (regression in v18.07).
Fixed Properties > Reverse… broken if numeric region setting uses comma for decimal (regression in v18.07).
Fixed Overlay HTML editor easily destroys default scripts (introduced in v18.07) if WebVfx JavaScript extension enabled.
Fixed custom interlaced Export presets loading as progressive (regression in v18.07)
Fixed Timeline > Copy Timeline to Source > Export fails on unsaved (Untitled) project.
Fixed Text filter has aliased edges (regression in v18.07).
Fixed Stabilize video filter not available on Linux (regression since v18.06).
Fixed changing Speed in Properties breaks all filters on that clip (regression since v18.05).
Fixed Fade Out Video (and keyframes in general) broken on still images whose in point is > 0 (regression since v18.03).
Fixed accuracy of Properties > Duration for image clip on the timeline.
Some fixes for changing Settings > Video Mode after starting a project.
Fixed compositing of upper video tracks becomes broken if bottom video track is deleted.
Fixed images with alpha channel (e.g. PNG) on upper video tracks have dark edges after compositing if the Size and Position or Rotate and Scale filters are not used.

Below is a screenshot showing the new View > Layout menu.

New Version 18.06: Reverse, Detach, and Double-click

Fri, 01 Jun 2018 00:00:00 -0700

UPDATE: Version 18.06 has been re-released (build 18.06.02) to fix a new crash bug that was discovered.

Version 18.06 is now available for DOWNLOAD!

Not only did the previous version (18.05) introduce major features and changes but also many new bugs. Let’s just call that release a “technology preview.” We paid a lot of attention to the feedback and fixed most of the problems for this version. But that’s not all! Take a look at this:

Added Reverse to clip Properties menu.
Added Detach Audio to timeline clip’s context menu.
Added simple and advanced Keyframes to the Blur, Mask, and Saturation filters.
Added seek buttons for simple Keyframes.
Added ability to add and remove advanced Keyframes using double-click.
Added ability to drag advanced Keyframes to adjust both value and position.
(When dragging, hold down Ctrl key to adjust only value or Alt key to adjust only position.)
Added double-click to toggle simple Keyframes controls (circles).
Added double-click to toggle fade in/out controls on Timeline clip.
Added many animated (keyframes) presets to the Size and Position filter.
Added Hue/Lightness/Saturation video filter.
Added 5.1 surround support to the Copy Channel and Swap Channels audio filters.
Added caution message to GPU Effects confirmation dialog.
Added a Keyboard Shortcuts link to the Help menu.
Changed presets file format to YAML.
Changed Settings > GPU Processing to GPU Effects.
Reduced memory usage on 32-bit builds (by constraining multi-threading).
Upgraded FFmpeg to v4.0.
Integrated AMD AMF hardware-accelerated H.264 and HEVC encoders on Windows (Set Export > Codec to h264_amf or hevc_amf. Requires recent Radeon or AMD APU.)
Upgraded MLT to git master (v6.8.0 minimum required to build).

New Version 18.05 Adds Keyframes!

Thu, 03 May 2018 00:00:00 -0700

UPDATE: Version 18.05 has been re-released (build 18.05.08) to fix a new crash bug on Windows and various issues with fade in / out following the new keyframes feature.

Version 18.05 is now available for DOWNLOAD!

Keyframes

Perhaps the most requested feature is the ability to move or smooth pan-and-zoom images or digital photos. We chose to address that in a more general manner by allowing filter parameters to be key-framed and animated rather than build something specific. Well, after long wait and much work, this has been introduced with a new Keyframes panel. It has an icon on the main toolbar to open the panel. There is much to say about this new feature and be sure to watch the videos as they become available. Keep in mind that this is new, incomplete, and a little unstable. Here are more caveats:

No support for undo/redo (pending filter support for this)
No keyboard shortcuts yet
Not yet available for transitions or generators
Only the following filters support keyframes at this time:
- Gain / Volume
- Brightness*
- Circular Frame (HTML proof-of-concept)
- Color Grading* (no simple)
- Opacity*
- Size and Position* (simple only, no curve UI)
  
  * = including the (still experimental) GPU filter
Nearly every filter supports filter trimming (handles on the ends of the clip strip).
Some filters only support simple keyframes (in/out controls on the clip strip).

Some filters only support advanced keyframes (rows below the clip strip).

Simple and advanced keyframes cannot be used at the same time on a particular instance of a filter.
The keyframes cannot be dragged to new positions.
You cannot add a keyframe by double-clicking somewhere on its curve.
Not all parameters have a curve UI.
You can right-click an advanced keyframe to show a menu with:
- Remove
- Keyframe Type (interpolation):
  - Discrete (hold)
  - Linear
  - Smooth (Catmull-Rom spline)

Keyframes Tutorial Video

5.1 Surround Sound

Perhaps the least requested feature - but something that interests AV geeks (including the developers) - is support for different audio channel formats: mono (1) and 5.1 surround (6) in addition to the stereo that was always there. This is accessed via the Settings > Audio Channels menu and Export > Audio > Channels. Most users only need stereo; so, if you suddenly start to experience problems make sure that you did not leave this menu set to something other than stereo, which is the most stable. Also, this setting is saved into your project file (MLT XML), and the menu reflects the saved setting. However, it should revert back to the last setting you explicitly chose after starting a new project. This new feature also has notes and caveats:

View > Scopes > Audio Peak Meter and Audio Waveform shows each channel and their layout/order.
The Timeline audio waveforms does not show a waveform of each channel. (Really this is just a graph of the audio power level across multiple channels.)
No automatic mode that chooses the channel count from your first clip.
No support in the Balance, Copy Channel, and Pan audio filters (yet).
Some audio filters may crash with 6 channels!
Not all export formats and audio codecs support surround. AAC and AC-3 are two that come to mind that do.
Not every possible channel count and layout are supported (e.g. not 7.1).
Alternative 6 channel layouts require a FFmpeg “channel_layout” to specified in Export > Other and is not reflected in the audio scopes.

Other

Added Finnish translation.
Restored GIF Animation for Export.
Reduced memory footprint (especially for the Rotate and Size and Position filters).
Changed default Export settings to reduce output size by increasing GOP and number of B frames.

New Release 18.03

Fri, 02 Mar 2018 00:00:00 -0800

Version 18.03 is now available for DOWNLOAD!

UPDATE: version 18.03 has been reissued (18.03.06) to address a couple of new bugs introduced: a crash loading SVG images, and broken renaming tracks. As a bonus, the Mosaic video filter has been added.

Here are the highlights of this release:

Added a Sketch filter.
Added numeric fields to the Color Grading filter.
Added All option to Properties > Audio > Track.
Added Estonian translation.
Improved image loading speed on Windows.
Improved mouse-wheel & trackpad scrolling in Timeline.
Improved support for JACK Audio (Linux and macOS only).
Upgraded FFmpeg to version 3.4 and latest vpx for much faster VP9 encoding.
Upgrade MLT to v6.6.0.
Upgraded SDL to version 2.0.

New Release 18.01

Tue, 02 Jan 2018 00:00:00 -0800

Version 18.01 is now available for DOWNLOAD!

Here are the main fixes and enhancements in this new version:

Added Audio Spectrum Visualization filter.
Added support for font size and italics to the Text filter.
Added a Mask filter.
Another important fix for accuracy of XML time values, particularly for non-integer frame rates.

The following is a screenshot showing the new Mask filter with a diamond shape. This filter only writes into the alpha channel of the video, which is the transparency information. Therefore, it only shows results when compositing two video tracks on the Timeline.

New Release 17.12

Sun, 03 Dec 2017 00:00:00 -0800

Version 17.12 is now available for DOWNLOAD!

This new version of Shotcut includes improvements for performance, accuracy, and usability:

Added icon, progress bar, and time remaining/taken to Jobs panel.
Increased maximum resolution to 8192x8192.
Indicate if variable frame rate is detected in Properties.
Added Convert to Edit-friendly… dialog when variable frame rate or non-seekable file opened.
Added Convert to Edit-friendly… to Properties menu for video and audio files.
Adding, removing, and adjusting Fade In/Out filters now updates fade controls on the Timeline.
Major speed improvements for Timeline rendering, especially when changing zoom level.
Stop showing waveforms on muted tracks.
Fixed audio crackling on some systems.
Fixed accuracy of reading and writing time values, particularly for non-integer frame rates.

Shotcut tries hard to let you edit with many audio and video formats directly without a conversion or import process. However, like most video editors, there are some things that it simply cannot handle such as variable frame rate. Unfortunately many screen, game, and device capture tools create such files. Also, in order to support editing, Shotcut must be able to seek to a frame. This version now tries to detect if a file is variable frame rate or non-seekable and present a dialog to Convert to Edit-friendly format. To keep the process rather simple but still satisfy different users’ needs, it offers 3 pre-defined options. More than likely, all of them will create a file that is larger than the original, which is normal. However, at least you get some choice.

In addition, Shotcut (via MLT & FFmpeg) only does a basic seek test. When it succeeds, it is still not guaranteed to be frame accurate—that depends on many factors: format, codec, parameters of codec, the tool that wrote it, FFmpeg’s code, MLT’s code, versions, etc. There is simply no good way to reliably test for that at the moment. Also, even when seeking works, some files and the way they were encoded seek slowly and may require Settings > Interpolation > Bilinear or better to increase accuracy making it even slower. Therefore, you can choose to convert any audio or video clip to one of the edit-friendly (frame accurate and relatively fast-seeking) formats by using Properties > Menu > Convert to Edit-friendly….

New Release 17.11

Thu, 02 Nov 2017 00:00:00 -0700

UPDATE: Version 17.11 has been re-released (build 17.11.07) to fix a crash on MP3s with album art - a bug since v17.03.

Version 17.11 is now available for DOWNLOAD!

This new version of Shotcut has quite a few fixes plus the follow set of changes and additions.

Changed add-filter menu to be embedded instead of popup.
Added Master label to Timeline.
Show filters icon on track heads if track is filtered.
Prioritize ‘0’ shortcut for Timeline over Playlist.
Do not adjust timeline zoom until slider is released.
Added warning dialog to Export if file cannot be written (e.g. due to permissions).
Added warning dialog to Export if chosen file is in the project.
Added warning dialog to Export if the drive is low on space.
Added Nepali translation.
Added button to Text filter to insert the # symbol.

Shotcut lets you attach filters to many things - not only clips on the Timeline. You can also attach filters to a track or even the entire timeline. In previous blog and forum posts, I have referred to the top left corner block of the timeline as “cornerstone” for lack of another reference. Also, I compared the ability to filter the entire timeline (the result after compositing and mixing) as similar to the “master out” volume slider on a sound mixing console. Therefore, I added the label Master to this selectable block. Furthermore, if you had added a filter to a track (by selecting the track head) or to Master, then you could easily forget about it. Or it could have even occurred by accident! Therefore, Shotcut now shows a Filters icon on a track head if it has filters.

See the screenshot below. The Filters panel is showing the filters applied to Master because it is selected, and there is a Filters icon on the Master track head to indicate that it has filters.

New Release 17.10

Mon, 02 Oct 2017 00:00:00 -0700

Version 17.10 is now available for DOWNLOAD!

Fixed multi-threaded decoding with FFmpeg v3.2.
Added 1080p 59.94 and 60 fps video modes.
Added support for NVENC to Export panel.

After upgrading FFmpeg to v3.2 in the previous release, we discovered a performance regression because multi-threaded was not working. That is fixed now.

One thing that came with the FFmpeg upgrade is NVENC, which is NVIDIA’s hardware-based H.264 and HEVC encoding for Linux and Windows. The quality is not as good as x264 and x265, but it might be faster for previewing an export or capture or just to play around with. To use it, you must have a NVIDIA GPU that supports it. You must choose “h264_nvenc” or “hevc_enc” from the Export > Video > Codec drop-down list - NOT the Format list. There are not presets provided. You can use the Export defaults or one of the H.264 or HEVC presets and change the codec. Just because it is listed does not mean it will work. The codec is listed without doing any capability test. If you right-click the Export job and choose View Log, then it may show some errors if it is not working. HEVC does not support B frames on most (all?) current devices and drivers. This version of Shotcut makes the Export > Codec rate control fields supply the correct options for NVENC.

New Release 17.09

Mon, 04 Sep 2017 00:00:00 -0700

Version 17.09 is now available for DOWNLOAD!

While this version contains the usual round-up of fixes and translation updates, it also contains some technology updates:

Renewed the code signing certificate for the Windows installer and executable.
Updated SDL to v2.0
Updated FFmpeg to v3.2
Updated x264, x265, and vp8/9 to the latest stable versions.

In addition, primarily for school/institution installations, we added the ability to turn off the welcome message that suggests to check for an upgrade. This works by either running the shotcut executable with the --noupgrade command line option. Or, one can add the option “noupgrade” to the config file or registry, under the General section with the value “true”. This option also hides the Help > Upgrade… menu item.

New Release 17.08

Tue, 01 Aug 2017 00:00:00 -0700

Version 17.08 is now available for DOWNLOAD!

This version fixes some bugs and tweaks a few things as well:

Increased maximum Timeline zoom level.
Increased Speed field precision to 3 decimal places.
Increased maximum value for Speed field to 200x.
Added Norwegian Bokmål translation.

New Release 17.06 with Linux SDK

Thu, 01 Jun 2017 00:00:00 -0700

Version 17.06 is now available for DOWNLOAD.

This version changes the maximum duration for a still image from 10 minutes to four hours. As with previous versions, if you need an image to appear longer, you can add the image more than once. In addition to some other bug fixes, this version fixes a broken Chinese translation and adds a Hungarian translation.

For a while now, we have provided information about how to setup a development environment on Windows to hack Shotcut. As part of that, we created a Windows SDK that bundles together most of Shotcut’s dependencies as well as special build of Qt 5 that still includes QtWebKit. These requirements still make development on Linux troublesome for new or casual contributors.

Lastly, I want to remind readers of the video instruction course by James Woo . Yeah, there are quite a few YouTube videos now including our own, but they are so-so. James’ series is clear, concise, comprehensive, and a good value. There are now over 40 tutorials for only $29!

New Release 17.05

Wed, 03 May 2017 00:00:00 -0700

Version 17.05 is now available for DOWNLOAD.

This version just fixes some bugs and updates translations. In particular, it fixes a long standing bug that, on Windows, files with non-Latin characters in the name or path can not be opened or saved.

New Release 17.04

Sun, 02 Apr 2017 00:00:00 -0700

Version 17.04 is now available for DOWNLOAD.

Fix crashing on launch on the new macOS 10.12.4.
Added Japanese translation.
Added Turkish translation.

New Release 17.03

Thu, 02 Mar 2017 00:00:00 -0800

Version 17.03 is now available for DOWNLOAD.

Converted the track toggle buttons to icons.
Now, you can press Del or Backspace to delete a selected item in the Recent panel.
Playback now pauses at the out point in the Source player. (After pause, you can press play again to continue beyond the out point.)
Some stability improvements.
Performance boost for Size & Position and Rotate filters on multi-CPU systems.

Video Tutorial: Record a Voice Over

Sun, 19 Feb 2017 00:00:00 -0800

There is a new video tutorial about how to record a voice over from the microphone using the latest version 17.02 of Shotcut.

Regressions, We've Had a Few

Wed, 01 Feb 2017 00:00:00 -0800

Lately, we have been focused primarily on bug fixes, and sometimes a bug fix introduces a new, often times worse bug, which is called a regression. Due to major regressions in v17.01 all users are strongly encouraged to
UPGRADE TO VERSION 17.02.

Fixed drag-n-drop from other than C: drive on Windows.
Fixed ‘/’ getting added to front of file paths on Windows.
Fixed the MLT XML repair tool not correctly handling decimal point in some configurations.
Fixed opening a network stream.
Improved support for image sequences.
Improved device capture.
Added Slovenian translation.

All device capture now occurs in the background. This makes it possible to record voice overs while playing the project. I plan to make a video to show how to do this soon.

New Release 17.01

Mon, 02 Jan 2017 00:00:00 -0800

Version 17.01 is now available for DOWNLOAD.

This version is just bug fixes plus a Chinese translation for Taiwan was added.

Version 16.12

Sat, 03 Dec 2016 00:00:00 -0800

Version 16.12 was released today and is available for DOWNLOAD.

Added Constrained VBR for the video codec rate control mode to Export.
Added Fixed option to video GOP to Export.
New audio mixing mode that does not affect levels.
Increased usage of floating point for audio processing to improve quality.
Added Occitan translation.
More fixes for copying filters and LUT (3D) video filter.

More About the New Audio Mixing

The first thing you need to know about the new mixing mode is that it only applies to new projects. You might have already adjusted volume levels in existing projects, and we did not want to affect that.

Versions before 16.10 used a mixing technique that tried to be clever about generally preserving the levels of all sources without clipping, but it was discovered that it may introduce artifacts. So, versions 16.10 and 16.11 switched to a simpler method that adds samples, but it was also averaging them to avoid clipping, which was found to adversely affect levels. So, the new approach in this version is to simply add samples.

As a result, you may experience clipping. Now, as long as there is so-called headroom in the level each of source, this should rarely be a problem because high level samples from each source are rarely correlated. Here is where the Normalize filters are your friends because not only do they bring all sources to the same level, but the default target level includes headroom. In addition to listening for clipping, you can visually monitor it using the Peak Meter and/or Audio Waveform scope in the View menu.

If each source has headroom in its level but you still experience clipping, you can add a Gain/Volume filter to the Timeline - select the cornerstone at the top, left of the Timeline and use the Filters panel. This is like the Master Out gain control on a mixing console. Reduce the gain until you eliminate the clipping. If you find that you need to lower the gain more than you like try adding the Limiter filter.

Version 16.11 - Now a Portable App

Wed, 02 Nov 2016 00:00:00 -0700

Version 16.11 was released today and is available for DOWNLOAD.

By popular demand, this version includes a new so-called portable app feature. A portable app is one that can be run without having to install and register components into the system. Rather, it is a self-contained folder for the executable and its bundled dependencies. Shotcut has always been portable in this sense regardless of the operating system. Portable apps can be put on a USB stick/drive and run from there. Then, you can use the app from computer-to-computer simply by plugging the USB stick. However, to be truly portable, the app should also use the USB stick to store settings and other app data.

Like most apps, Shotcut has an app data directory wherein it stores its thumbnails/waveforms database, presets, and log file. Normally, it stores settings in a platform-defined manner such as the registry on Windows or a plist file in ~/Library on macOS. Now, you can set the app directory using the command line option --appdata <directory> or the Settings > App Data Directory menu. When you do, then settings are instead saved in an INI file in the designated folder. If you use the menu, Shotcut will try to migrate everything from the current location to the new location only if there is not existing Shotcut data in the new location. Otherwise, it simply lets you start using the new directory adopting the settings and data. If you use the command line option, the new menu item is hidden making it possible to integrate the app into an app launcher/updater more seamlessly.

Here are some other changes in this version:

Fixed drag-n-drop to Timeline after moving clip to different track.
Fixed LUT (3D) filter for languages/regions that use comma for decimal point.
Fixed Properties > Speed on macOS for languages/regions that use comma for decimal point.
Added Gaelic (Scottish) translation.

Return of the 32-bit Windows Build

Sat, 01 Oct 2016 00:00:00 -0700

Improved compatibility

Version 16.10 was released today and is available for DOWNLOAD.

The 32-bit Windows version is back by popular demand! 32-bit apps still have the significant limitation that they can only use 2 GB RAM, and Shotcut still uses a lot of RAM. We will see what we can do to reduce memory usage in the coming months. In the meantime, consider limiting yourself to working in 720 pixels of vertical resolution for multitrack projects, and try to avoid using very high resolution still images (scale them down before using them in Shotcut).

For Linux users, when we upgraded the build machine OS to Debian 8 in July for the 16.07 version, we lost a lot of compatibility with older versions of popular Linux distributions. Some people only lost the Stabilize filter. When this combined with the Qt upgrade in the previous release - v16.09 - many users, such as those on Mint 17 or Ubuntu 14.04, could no longer run the latest Shotcut. That is fixed in this release by using Ubuntu 14.04 as the base OS image for the build.

Lens Correction and 3D LUT Filters

A forum user has contributed a Lens Correction video filter. Thanks TwitchyMcJoe! Another forum user suggested to add a 3D LUT filter. Fortunately, this was already available through the MLT+FFmpeg engine, and it was easy to add a UI to expose this powerful filter.

Merge Clips on the Timeline

If you have adjacent sub-clips from the same source clip on the timeline, now you can right click to open the context menu and choose “Merge clip with next” to merge the clips into one.

Tiles and Icons Views for Playlist

Thu, 01 Sep 2016 00:00:00 -0700

Thanks to Shotcut developer, Harald, new Tiles and Icons Playlist view modes were added to the new version 16.09, which is now available for DOWNLOAD. The old view mode is still available and named Details.

Video Tutorial: Film Restoration

Wed, 31 Aug 2016 00:00:00 -0700

In this tutorial Shotcut developer, Brian, shows how he uses some filters to clean up old, family 8mm films he had converted to digital.

The Discussion Forum Is Now Free

Wed, 31 Aug 2016 00:00:00 -0700

I decided to convert the discussion forum to be free-of-charge and supported through a moderate level of advertising. Some of you may know that I used to request a donation to gain membership. If you made a donation in the past 30 days, then advertising is turned off for you for next month. There might be an add-on package of services in the future that will include no ads in the forum. Thank you to everyone who contributed financially this year.

IMPORTANT: As a result of this change, if you already have an account on the forum you must reset your password.

Obviously, with the forum being free, the activity is going to increase, and I may not always be very active in there. Some employers have said something like “if only we could clone him….” ;-) Well, I am training my daughter who is in college to help me. Initially, she will be providing technical support and doing some web site maintenance. Eventually, I hope she can fix bugs and do development. This endeavor is turning into a nice father-daughter, dynamic-duo story!

Version 16.08 Re-released

Fri, 12 Aug 2016 00:00:00 -0700

The “performance boost for opaque clips on video tracks higher than V1” that was introduced for v16.08 was causing crashes with some filters. This was fixed in a new version 16.08.12.

New Release 16.08

Mon, 01 Aug 2016 00:00:00 -0700

Version 16.08 is now available for download. This version mostly contains fixes, but there are a couple of additions:

Added count-down (or up) generator: File > Open Other > Count
Major performance boost for opaque clips on video tracks higher than V1 with track Composite enabled and Blend mode: Over.

Export Frame in new v16.07 Release

Fri, 01 Jul 2016 00:00:00 -0700

Export Frame is a new feature in the File menu of Shotcut version 16.07. This feature lets you save the frame currently displayed in the Shotcut viewer as a still image file in PNG, JPEG, BMP, or WebP format. Simply use an appropriate file name extension to choose the desired format. This saves the frame as it is shown including the options in the Settings menu and Filters. Upon save, the new file is added to the Recent panel to make it convenient to open and use in Shotcut. This makes it easy to achieve a freeze frame effect. Simply navigate to the frame you want on the timeline, export it, open it, and Paste it. This also makes it convenient to create a custom thumbnail for your web video: export a frame, double-click it in Recent to open it in the Source viewer, add a text filter to title it, and re-export it.

As usual, there is also a collection a fixes - including for the new version checker, which did not work on many systems. Trimming on the timeline has been improved. In previous versions, if you accidentally started a transition while trimming and changed dragging direction to try to return to a trim operation, it would behave badly and create an undesired single-frame transition. Not only was that fixed, but also now you can remove a transition by trimming it away. So, Remove transition is now an action that can appear in your undo History that you can undo and redo.

New Release 16.06

Wed, 01 Jun 2016 00:00:00 -0700

Version 16.06 is now available for download. There are number of changes and additions in this release:

Show red outline on scrub bar of Source player to indicate selection.
Added Cut, Copy, and Paste to Edit menu and Timeline tool bar.

Changed double-click on Timeline clip to select+seek instead of copying to Source player.
Changed Timeline keyboard shortcut A to append.
Changed Timeline keyboard shortcut C to copy.
Changed Timeline keyboard shortcut Enter to seek to start of clip.
Added Peak and True Peak meters to the Audio Loudness scope.
Added version/upgrade-checker.
Added check for missing files when opening .mlt XML project file.
Added dialog to locate and resolve (relink) missing files in project file.
For clips with speed changed, added support for saving and loading relative path and file names.
Added Export EDL to the File menu.
Added YouTube preset to Export (which does the same thing as not changing any export settings, not selecting an export preset, or clicking Reset).
Updated Blackmagic Design SDI/HDMI output to work with recent driver updates.

New Release 16.05

Sun, 01 May 2016 00:00:00 -0700

Version 16.05 is now available for download. This version is mostly just fixes, but there are a few small additions and changes:

Added Remove to Jobs panel.
Added 25% option to player’s Zoom button-menu.

Moved status messages front and central and removed status bar.

New Video Tutorial Course by James Woo

Fri, 08 Apr 2016 00:00:00 -0700

Shotcut power user, James Woo, has created a wonderful course on how to use Shotcut.

Currently, it contains 24 videos and costs $25, but it only costs $20 using the coupon code in the link on this blog post! As the lead developer of Shotcut, I reviewed the entire course, and I think it is very good. James clearly and accurately explains many thing from basics to more advanced techniques such as picture-in-picture, chroma keying, and using custom HTML. The lessons are sequenced in a nice progressive manner, but you can also directly visit specific topics. These are presented in the English language.

New Release 16.04

Fri, 01 Apr 2016 00:00:00 -0700

Version 16.04 is now available for download.

Added Normalize: One Pass audio filter (existing Normalize renamed Normalize: Two Pass.
Added Audio Loudness to View > Scopes.
Added Brightness video filter for CPU and GPU.
Added Contrast video filter for CPU and GPU.
Added Reduce Noise video filter for CPU only.
Added More Information to clip Properties overflow-menu.
Added Start Integrity Check Job to clip Properties overflow-menu.
Added auto-rotate for video clips with orientation metadata.
Install ffplay and ffprobe executables.
Fixed frequently reported problem with black video on Export.
Fixed a few crashing bugs.
Added an option to Windows installer to remove registry settings to help people with new crash-on-launch problems.
Reduced memory usage when exporting a playlist or multitrack project.
Improved visual feedback about what is selected in Timeline, Properties, and Filters views.
Added a Ukranian translation.

New Release, Web Site & Forum

Tue, 01 Mar 2016 00:00:00 -0800

Version 16.03 is now available for download.

Changed player tab Program to Project.
Changed panel name Encode to Export.

Added an export preset for animated GIF.
Upgraded FFmpeg to v3.0.
Upgraded MLT to v6.0.0.

New Release 16.02

Tue, 02 Feb 2016 12:13:00 -0800

Version 16.02 is now available for download. This release is mostly just bug fixes and improvements to the integration of the clip speed option in Properties. There are a few new, minor things::

Audio waveforms on timeline are updated incrementally as progress is made.
Allow dual pass encoding for CBR.
Added Show Video Thumbnails option to the timeline menu.
Added Rebuild Audio Waveform to a timeline clip’s context menu.

New Release 16.01

Sat, 02 Jan 2016 12:13:00 -0800

Version 16.01 is now available for download. We added two big new features for this release: clip speed and chroma key! Here is the full list new things:

Added Speed parameter to Properties for an audio/video clip.
Added Properties views for track and timeline when selected. Click track head to select track; click the timeline's cornerstone (top left block) to select the timeline.
Added Blend mode to track properties (not available in GPU processing mode; only applies when compositing is enabled in the track header).
Added Alpha Channel: View video filter.
Added Alpha Channel: Adjust video filter.
Added Chroma Key: Simple video filter.
Added Chroma Key: Advanced video filter.
Added Key Spill: Simple video filter.
Added Key Spill: Advanced video filter.

All of the new video filters are intended to facilitate chroma keying; however, the Alpha Channel filters do have some general usefulness outside of keying. Please note that “Alpha Channel: View” is not really intended to be an effect that gets baked into your rendered and encoded output. You can leave it in the filter list, but toggle the filter by clicking the checkbox or double-clicking its name in the list of attached filters to turn it off. “Key Spill” is also know as “color spill” and “spill suppression,” and it refers to the background color bleeding into the foreground. None of these new video filters can utilize GPU-processing at this time; however, they do support multi-core rendering when Settings > Realtime is turned off or when exporting. You can use them in conjunction with GPU processsing; they just will not take advantage of the speed and quality the GPU mode provides.

Regarding speed control, it is a simple frame-drop/-duplicate approach. It does not attempt to do any frame-blending or advanced optical flow analysis. Now, with that said, you can get nice results slowing down high frame-rate footage. However, you must ensure that your project is running at a typical 24 - 60 fps because Settings > Video Mode > Automatic may otherwise adopt the clip’s frame rate. (In automatic mode, the project is based on the first item you add to the playlist or timeline or on the opened clip if playlist or timeline is not used.)

New Release 15.12

Tue, 01 Dec 2015 13:55:00 -0800

Version 15.12 is now available for download.

This release mostly only contains bug fixes, but there are a couple of new things:

a Slovak translation (thank you Stano110)
the ability to restore a crashed session not yet saved as a project (Untitled)

Version 15.11 re-released for Windows

Tue, 03 Nov 2015 10:35:00 -0800

Shortly after the first release of 15.11 for Windows we discovered two new major problems that were fixed for a new 15.11.03 version, available now for download. The problems were a failure to launch due to a missing DLL in the installer, and encode jobs stuck in a pending state and not completing.

New Release 15.11

Sun, 01 Nov 2015 15:59:00 -0800

Version 15.11 is now available for download. Here is the quick list of new things:

Added Rutt-Etra-Izer video filter.
Added audio/video device and screen capture for OS X.
Added screen capture for Windows.
Added keyboard shortcuts for trimming on Timeline: I, Shift+I, O, Shift+O.
Added support for ripple trimming on Timeline.
Added Application Log to View menu.
Added Save button to text viewer dialogs (logs, XML).
Added video Deinterlace, Interpolation, and Parallel-processing options to Encode panel.
Reorganize the Settings menu and added headings.
Added Close action to File menu.

The Rutt-Etra-Izer filter might seem like a strange addition, but there is an interesting backstory to it. When I discovered it and learned about the WebGL version by Felix Turner a couple of years ago, I thought I ought to be able to make it work with Shotcut’s HTML filtering system (WebVfx). It requires the ability to read pixel data in JavaScript, which has not really worked correctly until the Shotcut upgrade to Qt 5.5. So, now we have it.

For a long while now, we have supported audio and video devices on Linux such as microphones, webcams, and more as well as screen capture. A year ago, we added A/V device support on Windows. With this release, thanks to the recent upgrade to FFmpeg 2.7, we extend device and screen capture coverage to all supported operating systems.

The last big new thing is a boost for trimming on the timeline. The new keyboard shortcuts only let you reduce the duration of a clip. It might be easier to think of this as a smarter way to split/slice a clip on the timeline, and it affects the clip under the playhead - not the currently selected clip. Very often, one - based on their technique - splits a clip and then removes one of the new pieces. Well, these trimming keyboard shortcuts are actually like two steps in one: split and remove. Just like elsewhere, there are two ways to remove: lift and ripple-delete. Ripple means to affect the position of all following clips and not leave (or extend) a gap. It is named after the ripple effect of throwing a rock in a pond. That is why the timeline toolbar icon looks like a few circles. Oh, and that ripple button now takes on a newly expanded role of also toggling whether drag-trimming the ends of a clip with the mouse ripples the following shots. I will try to make a video soon to better explain and show all of this.

Version 15.10 re-released

Tue, 06 Oct 2015 08:13:00 -0700

We found a major regression with GPU processing in v15.10 release (15.10.01 in Help > About). Now, this is an experimental feature, but some people are using it or like to give it a try. Therefore, I just uploaded a new version 15.10.06 with no new features over .01.

New Release 15.10

Thu, 01 Oct 2015 19:21:00 -0700

Version 15.10 is now available for download. This is a bugfix-only release - no new features. Except, there are new Dutch and Russian translations - thank you, asilnevs and rayanayar.

After the addition of new features such as insert/remove track and a major upgrade to libraries in recent releases, we just wanted to focus further on stabilization and bug-fixing. We have fixed some issues in regions that do not use a period as the decimal mark. Why only some? Well, we are not entirely confident we have reproduced all possible problems. However, we did find and fix a major bug in that area. In addition, when opening a project document, we added a function to look for a malformed project containing both periods and commas in some numeric values. Why only “some?” Because, with filters there are many possible values to locate. In addition, in this first pass on that function, we wanted to be conservative about how heavily we modify the document. Only some fixes are better than horribly mangling it into something useless, right? Thus, only edit timing and size/position rectangle values are repaired. Do not be frightened by this; your original project is not modified. First, you will receive a warning dialog including the option to not repair the project. Also, it makes and uses a copy of your project file with “Repaired” in the new name.

You will also find some fixes for long-standing problems such as:

audio waveforms not appearing correctly for long clips on the timeline,
drag-n-drop from Windows Explorer not working reliably,
animated GIFs loading as a still single image,
crashes opening a project containing a Text filter,
crashes using the draggable fade controls on the timeline, and
missing scroll bars around filter parameters.

New Release 15.09

Thu, 10 Sep 2015 23:20:00 -0700

Version 15.09 is ready for download and aims to improve compatibility and stability on modern systems. This was primarily achieved by upgrading to Qt 5.5. This fixes compatibility issues on Linux systems with AMD graphics. It also introduces a DirectX display method option on Windows (when not using GPU processing) for systems with inadequate OpenGL. With that said, there are some caveats; notice we said “modern systems.” The new version is 64-bit only for all operating systems. After all, 64-bit CPUs have been available for nearly 12 years. Also, the OS X version requires at least OS X 10.8. In addition:

Added Scrub Audio to Settings menu.
Added Display Method to Settings menu (Windows only).
Added Portugal Portuguese translation to Settings menu.
Added Mute audio filter.
Updated FFmpeg to v2.7.

New Release 15.08

Mon, 10 Aug 2015 21:28:00 -0700

Well, what do you know? It turns out there is a v15.08 for download after all! It was delayed due to build infrastructure problems and travel. While we have been focusing lately on a major UI toolkit upgrade, I wanted to get some fixes out. In addition, there are some new things:

Added a Greek translation (thank you, firewalker).
Added a Ripple All Tracks option to the Timeline menu (default is off).
In version 15.06, we changed insert and delete operations to ripple (move following clips) across all unlocked tracks. It turns out that enough new and casual users found that disorienting and did not realize there is track locking to control it. Therefore, we added a toggle option in the timeline menu (see button on timeline toolbar). More advanced users who want this behavior will have to turn it on.
5 new audio dynamics filters (thank you, Lauren):

Compressor
Delay
Expander
Limiter
Reverb

New Release 15.07

Thu, 02 Jul 2015 09:30:00 -0700

Version 15.07 of Shotcut is now available for download. Here is a quick rundown on the new features and changes with details to follow:

4K UHD support
5 new video filters:

Old Film: Dust
Old Film: Grain
Old Film: Projector
Old Film: Scratches
Old Film: Technocolor

5 new audio filters:

Bass & Treble (3-band graphic equalizer)
Band Pass
High Pass
Low Pass
Notch

Added Insert Track and Remove Track
New default Encode settings produce a better quality H.264 MP4 file
Composite now defaults to on/enabled for new video tracks

Shotcut has been able to do 4K for a while now if you made a custom video mode or correctly use automatic mode. However, there were a few things we wanted to do before making it official. First, you really need to be using a 64-bit build, and we delivered that for Windows in the previous release. For this release, we added 4K video modes to the Settings menu and extended our support for Blackmagic Design 4K SDI & HDMI devices (tested output with Intensity Pro 4K). The new audio and video filters were produced by two teenage daughters for a summer job/project! These old film video effects can be considered toy filters. The film grain effect does not try to emulate any real film stock, and the Technocolor filter does not try to faithfully reproduce the 20th century Technicolor processes. It merely intends to approximate the look. Therefore, our spelling with an 'o' is intentional to avoid any false claims and association with the trademark.

Often, we get asked "how do I export?" To which we sometimes reply, "Encode > Encode File > enter a filename ending with .mp4" as beginners or casual users do not want to figure out a preset or custom settings to use. However, that did not always produce great results. The new default Encode settings are setup to produce a good - but not big - MP4 for any resolution and frame rate. This means it no longer defaults to using the filename extension to choose format and codecs. Previously, it would produce a 2 Mb/s average bitrate file, which did not look good for 1080 or higher. The new default uses a quality-based variable bitrate making it more convenient and easy to output for modern devices and Internet sharing.

Another frequently asked question is how to make a picture-in-picture or make a new video track use the alpha channel (transparency). It seems most people are using additional video tracks for overlay/compositing. Therefore, we decided to enable composite by default for additional video tracks. If you are not using the video track for that and do not like the decreased performance as a result, you can simply click that 'C' button in the track header to turn it off.

New Release 15.06

Mon, 01 Jun 2015 19:57:00 -0700

Version 15.06 of Shotcut is now available for download. We are pleased to offer our first 64-bit version for Windows! As exciting as that may be, please keep in mind that it is new and therefore somewhat experimental.

Added Audio Spectrum analyzer.
Changed audio Gain filter to use dB and log scale.

Added a toggle button to Lock a track.
Changed Insert and Ripple Delete to ripple across all unlocked tracks.
Changed keyboard shortcuts to adjust track height to Ctrl+- and Ctrl+=.
Added keyboard shortcuts to toggle track:

Mute - Ctrl+M
Hide - Ctrl+H
Lock - Ctrl+C

Version 15.05 re-released

Wed, 06 May 2015 16:21:00 -0700

We noticed a couple of major new bugs in versions 15.04 and 15.05.02 (according to the download filename and Help > About). Therefore, we made some quick fixes, which you can download now (15.05.06):

Fix frequent crashes with both Settings > GPU and Settings > Realtime turned off.
Fix the Timeline Split command producing incorrect results. If you saved a project with the faulty Split command in the short-lived v15.05.02, then the problems were also saved to the project, and there is no automatic fix for it. You should remove the problematic shots and recreate them.
On OS X, fix a crash when choosing Remove from the Timeline clip/blank context menu.
On OS X, fix the new keyboard shortcuts for selection control (select under play-head, move selection, deselect).

New Release 15.05

Sat, 02 May 2015 09:17:00 -0700

Version 15.05 of Shotcut is now available for download. I want to welcome and thank a new developer on-board named Harald (metellius). I also want to mention and thank a developer named Brian (pez4brian) who has been helping out for more than a year now.

Add Distort option to Size and Position filter.
Add video Cut option to Transition Properties.
Code-sign Windows executable and installer.
In Timeline, operate on clip under the play head if nothing is selected.
New keyboard shortcuts for Timeline:

Select clip under play head: Ctrl+Space.
Move selection one item to the right/left: Ctrl+Right/Left.
Blanks can be selected to remove/ripple-delete: X or Shift+Del or Shift+Backspace.
Deselect everything: Ctrl+D.
Open As Clip: Enter/Return.

New Release 15.04

Wed, 01 Apr 2015 22:07:00 -0700

Version 15.04 of Shotcut is now available for download. This is mainly a bug fix release, but there a few enhancements:

Added an audio tone generator (in File > Open > Other).
Now you can set a new default duration for audio or video fade filters.
The WebM VP9 encode preset enables multi-threaded encoding.

15.03 Release Video

Tue, 03 Mar 2015 19:46:00 -0800

This video shows the changes made in version 15.03.

New Release 15.03

Tue, 03 Mar 2015 15:00:00 -0800

Version 15.03 of Shotcut is now available for download with the following changes and enhancements.

Add Update button to Playlist panel.
Double-clicking a successfully completed Encode job, now opens the result in Shotcut.
Consolidate GPU and Video filters in Filter menu.
Add View > Scopes > Audio Waveform.
Move audio peak meter to View > Scopes > Audio Peak Meter and main toolbar button.
Move volume slider to player toolbar icon.

New release 15.02

Sun, 01 Feb 2015 05:13:00 -0800

Version 15.02 Shotcut is now available for download with the following enhancements:

Add x265 codec.
Based on the same principles and code as the esteemed x264 project, x265 provides a solution for the emerging H.265/MPEG High Efficiency Video Coding (HEVC) standard.
UDPATE: There is also a new Encode preset named "HEVC Main Profile."
Add video quality measurement tool.
Upon successful completion of an encoding job, access the job's menu by right-clicking it in the job list or by selecting it and using the menu button at the bottom of the Jobs panel. Then, choose Measure Video Quality. A file dialog opens for you to enter the name of a text file to contain a report containing PSNR and SSIM values for each video frame. When the measure job completes successfully, open its menu in the same manner to view the report or to open an original-on-top/encoded-on-bottom view in the player.
No longer auto-plays upon opening a playlist and multitrack project.
Auto-select all text upon giving a timecode field focus. See the Keyboard Shortcuts page for info about entering time values.

Version 14.12 re-release

Sun, 07 Dec 2014 11:58:00 -0800

We recently discovered that versions 14.09 - 14.12 were failing to launch on systems running OS X 10.8 and older. In the course of fixing it, we believe the problem could affect more than just those versions of OS X - a Linux user reported a similar problem. Also, we noticed a regression on Windows with the ability to drag-n-drop files onto the player window after a filter using on-video controls (VUI) had been used at least once during the session. Therefore, a new 14.12.06 build of the 14.12 release is available for download to address these problems.

New Release 14.12

Sat, 06 Dec 2014 11:58:00 -0800

In addition to little fixes here and there, this version has a new filter menu to prevent the menus from getting too full as we add more.

Now, you can flag filters as favorites. The default list upon opening the menu is your favorites. Click the other icons to view all filters of that type. In addition, when GPU processing is enabled, you can use CPU-based video filters in addition to the GPU filters. We only show the CPU filters that are not redundant with their GPU counterpart. We only allow you to place CPU video filters after all GPU filters, but you can still reorder within those groups. This is done mainly for performance reasons - to prevent the video from having to go back and forth between CPU and GPU memory.

New Release 14.11

Sat, 01 Nov 2014 13:15:00 -0700

The new version 14.11 of Shotcut is now available for download with the following enhancements in addition to the usual bug fixes:

The HTML5 features are finally available on Windows!
Add source code editing to the HTML editor.

Add 3D Text filter based on WebGL, typeface.js, and three.js.
Add support for DirectShow devices on Windows in the Open Other dialog.
Add the Opus audio codec.

Change the VP9 WebM preset to use the Opus audio codec.
Add support for the #localtime# keyword to the Text filter (no button yet).
Restart instead of simply closing the app when changing the GPU or language settings.
Change the Redo keyboard shortcut to Ctrl+Y on Windows only.
Save file paths in MLT XML with relative names for assets in the same folder or sub-folder. This makes it easier to use a relocatable project folder.
Add scale and offset parameters and a preset widget to the Rotate filter. Usually after rotating a video, part of the image has been clipped. These new parameters provide control for that clipping processing including no clipping.
Add Italian translation.

New Release 14.10

Wed, 01 Oct 2014 10:00:00 -0700

Since it is the beginning of the month, it is time for a new release (v14.01) of Shotcut. This is primarily a maintenance release to fix some bugs. However, this version does introduce a Polish translation. Also, for Leap Motion control, the roles of open and closed hand have been swapped - close hand to pause, open it for shuttle control. This makes it operate more like other Leap apps and makes it more reliable when moving your hand in and out of Leap’s view. In addition, FFV1 encoding has been fixed and restored. Thank you to everyone who has shown your support.

Compositing Improvements

Wed, 03 Sep 2014 23:09:00 -0700

We recently released version 14.09 with new compositing features. Compositing for a track on the timeline has been available for some time by clicking the C button in the track header. However, there was no way to control the size, position, and opacity of the video or graphic. This could have been made available earlier as a filter with a UI that simply uses sliders and numeric fields, but that is not fun to use! We wanted to provide a way to more directly interact with the video to adjust the size and position. We needed to develop a new capability to overlay UI controls on top of the video using the same QML technology we use for the filters and timeline. Now that capability is available as the Video User Interface, or VUI for short. The new Size and Position and Text filters provide a rectangle control in the VUI.

There will be a video tutorial coming soon to explain how to use this in more detail. The new Size and Position and Opacity filters can be used with both GPU or CPU processing, but the new Text filter is only available in CPU mode. Here are the complete release notes for v14.09:

Added WMV and WMA encode presets.
Enabled the video player zoom and pan controls for OS X.
Added Size and Position video filter with a rectangle control that overlays the video player.
Added a simple Text video filter also with rectangle control overlay. This is a dynamic text filter supports pre-defined variables: Timecode, Frame #, File date, File name.
Enabled parallel video processing for Encode File on systems with more than 2 logical cores when not using GPU Processing. This makes encoding faster when using filters, transitions, and compositing.
Added an Opacity video filter.
Added an option on video fade filters: Adjust opacity instead of fade with black.
Now you can add filters to an entire track by clicking the track head and using the Filters panel.
New projects created with this version now load much more quickly.

New Release 14.08

Fri, 01 Aug 2014 09:00:00 -0700

Shotcut 14.08 is now available for download. In the past month, we have just been continuing to fix problems while we work on some new features in branches. Hopefully, next month the new features will be ready.

Now the Stabilize video filter really does work on Windows.
Added a Gamma menu item to the Settings menu when in GPU mode, which performs gamma correction. Previously, the display gamma was fixed at sRGB, but now you can choose Rec. 709. Previously, when applying a GPU filter, Shotcut would output sRGB gamma when encoding to a Y'CbCr file, and that has been removed/fixed.
Transfer characteristic (gamma) metadata is now written to video files that support it (e.g., H.264).
The filter UI layout is now automatically adapts to a horizontal or vertical layout to suit more workspace layouts.
Upgraded FFmpeg to version 2.3.

New release 14.07

Tue, 01 Jul 2014 08:41:00 -0700

Shotcut 14.07 is now available for download. Here are the changes since previous release:

Added a "Remove Old Program Files" option to Windows installer.
Added an auto-save feature. You must first save a MLT XML project file for this to work; so, save a project shortly after you start making something.
Improved Video Stabilize and Audio Normalize analysis job handling.
Added a dialog to confirm exit if there are unfinished jobs.
Improved working with image clip duration on the timeline. Previously, you had to set a duration in the Properties panel before adding an image to the timeline, and then you could not trim the image clip to make it longer. Now, the duration property controls the out point and you can crop the image clip to resize the duration up to 10 minutes.

Filter UI general cleanup and new combination slider/numeric-spinner control. The tiny up/down arrows on the spinner are gone, but you can still use the cursor up/down keys as well as mouse wheel to increment and decrement. Also, the "thumb" on the slider is gone, but you can adjust the slider "bar" by clicking, dragging, or mouse wheel.

New release 14.06

Sun, 01 Jun 2014 21:23:00 -0700

Shotcut has moved to a monthly release cycle. That already happened unannounced for the month of May. Now we give you release 14.06, which is mainly just a bug fix release with some changes under the hood to prepare for future needs. Here are some of the improvements:

Fix opening files with names or paths that include extended characters on Windows.
Add logging of program execution info to a text file to help with troubleshooting. The logging is very limited at this time and mainly intended to help indicate app startup failures. The log is stored in the same location as the database and presets.
Show error message if trying to load MLT XML project file that is incompatible with current GPU processing setting.
Upgrade x264 from something that was 1.5 years old to latest.
Upgrade FFmpeg from version 2.1 to 2.2.
Upgrade Movit (GPU processing) from pre-1.0 to 1.1.1.
Update translations.

Playlist editing keyboard shortcuts changed

Thu, 03 Apr 2014 23:14:00 -0700

Previously, the X, C, V, and B keys could be used to edit the multitrack timeline or the playlist when the timeline is not being used (no tracks). This could be confusing, not to mention making it unable to use shortcuts to affect the playlist/bin in a timeline project. As of version 14.04.04, we now require the Shift key to be held when using X, C, V, and B to target the playlist; otherwise these shortcuts target the timeline.

New Feature - Cross-fades and Transitions!

Wed, 26 Mar 2014 21:00:00 -0700

As of version 14.03.26, audio cross-fades and video transitions have been added. Even though some other video editors also do it this way, it may be different for some. So, we made a tutorial to help get you started.

A very brief textual explanation is that you overlap adjacent clips on the same track either by drag-n-drop or by trimming. By default this creates a video dissolve with audio cross-fade. To change that, select the transition on the Timeline and view Properties to make a video wipe or to manually control the audio mix. Custom wipes can be provided by a grayscale image, and there are links to locations where you can get wipes that others have created in the FAQ.

This new feature does support GPU processing if your system supports that. However, while making this addition, GPU processing broke on Mac OS X in version 14.03.25, fixed in version 14.03.27.

There are still some sharp edges on this new feature that we will continue to improve. For example, currently Shotcut lets you (re)size the transition when there are not enough excess frames in the “handles” before the in point and after the out point of your shots. We need to add some limiters on the actions around that.

Fade In and Out

Sun, 02 Mar 2014 14:46:00 -0800

Fade in and out filters have been added as of version 14.03.01. There are 2 video filters - Fade From Black and Fade To Black - plus 2 new audio filters: Fade In and Fade Out. The video filters support GPU processing if you can use that.

As you can see in the screenshot, fade conrols are available on the shots directly on the timeline making it very easy and convenient to add the filters and adjust audio+video in a tandem/ganged fashion. Simply move the mouse pointer to the top-left corner or top-right corner of a particular shot to make a pulsating circle appear. Then, click and drag the circle control horizontally to drag-out a fade rectangle. But that does not mean you have to use the timeline to utilize these new filters. If you are simply working with a clip or playlist project, you can still apply and use these filters.

And before you ask, no, this update does not include or support cross-fading audio or cross-dissolving video. That is coming next.

Improved Drag-n-drop Into Timeline

Thu, 20 Feb 2014 14:57:00 -0800

Now, as of version 14.02.18, the clip rectangle aligns to the track, and there is snapping that can be toggled. Instead of an append-only operation, there are now overwrite (default) and insert (ripple) operations. Overwrite has been corrected to support overwriting multiple shots and gaps along with its corresponding undo action. Lastly, there is optional scrubbing in the program viewer while dragging.

GPU Processing on Windows Fixed

Thu, 13 Feb 2014 12:11:00 -0800

As of v14.02.12, GPU processing works again in Windows! Of course, you need a video card and driver that supports at least OpenGL version 3.2. This has only been tested on systems with NVIDIA, but it should work with other providers.

Also, as v14.02.13, drag-n-drop of shots from either the Playlist or the Source player into the timeline is working now on Windows and OS X. (Previously, it only worked on Linux.) This is very basic at the moment by only letting you append a shot to a track, but it was necessary to get it working across platforms before enhancing it.

Improved Stabilize and Normalize (EBU R128)

Tue, 11 Feb 2014 20:03:00 -0800

Thanks to contributing developers, Stabilize and Normalize filters are improved as of version 14.02.11. Normalize is now based on EBU R128 technology provided through libebur. This gives better results because R128 is based on perceived loudness instead of RMS or peak volume. Stabilize is using the latest and greatest version of vid.stab making it faster and yielding better quality results.

Playlist Changes For Timeline

Mon, 10 Feb 2014 18:00:00 -0800

As of version 14.02.08, we have changed some behavior of the Playlist and player that seemed necessary since the addition of the Timeline. It is still entirely possible to simply create a playlist project if you do not need multitrack. I myself often prefer to lay down my main story line using just a playlist. Then, maybe later I want to lay down a music bed. Therefore, we added “Add All to Timeline” to the playlist menu to “upgrade” a playlist project to a multitrack project. Now, the playlist also saves into the project MLT XML file along with the timeline. However, in a multitrack project, the playlist is like a media “bin” as seen in other programs - while still being optional. In addition, the player tabs now say “Source” and “Program” to reduce possible confusion having 2 Playlist tabs and 2 Timeline tabs on screen at the same time. Source shows a clip (or stream or device). In a playlist project, Program shows the playlist, and it shows the timeline in a multitrack project. Double-clicking a playlist item now always opens the shot in the Source player. This makes it more usable as a bin. In a playlist project, to seek to a playlist item, shift-double-click it or right-click it and choose Goto.

Multitrack Timeline

Sat, 28 Dec 2013 13:47:00 -0800

The new multitrack timeline is available as of version 13.12.28.

Please keep in mind that this is the first release of this feature. Most Shotcut development is done in the open, and this is not yet considered a ready feature. Still, it can be used to some degree of success if not expecting too much and being careful of some rough edges. Here is a quick list of what we have today:

works on all platforms
the player/viewer now is now tabbed: Clip, Playlist, or Timeline
multiple tracks - audio only (green) or audio/video (blue) tracks
adjustable track height
menu and toolbar at the top left
ruler strip at the top with timecode
playhead
track headers at the left
tracks are named using a standard V2, V1, A1, A2, ... convention
tracks can be renamed
track headers have toggle buttons for mute, hide, and composite
right-click [C] button in track header to more easily understand and access composite option
zoom slider at bottom, left
zoom using keyboard shortcuts 0 (reset), - (zoom out),. and = (zoom in)
notion of a current track with background tinted yellow
change current track by clicking header, track background, or up/down cursor keys
track scrolling - manually or automatically while playing
scrubbing

click on ruler or track background to seek to that point
drag on ruler or track background to scrub
hold down shift to scrub without having to drag (scim)
scrubbing at left & right edges automatically scrolls as-needed

thumbnails of in and out points of video with caching to storage between sessions
audio "waveforms" (technically, they are a graph of the audio level across all channels) with caching
notion of a selected clip, which is darkened
selecting a clip shows its filters in the filters panel
use menu at top left has to add an audio or video track
use menu at top left to close the timeline - both project and panel
all non-muted tracks mix audio
all non-hidden tracks can composite against a black background
append a clip to the current track via:

click + button,
press C key when timeline has focus
drag-n-drop from player or playlist (currently broken on Windows and OS X)

move a clip using drag-n-drop
trim clip in point by dragging its left edge (does not ripple)
trim clip out point by dragging its right edge (does not ripple)
snapping to edges of other clips and to the playhead
(hold Alt key to temporarily suspend snapping while dragging)
lift a clip: remove it without affecting position of other clips

select it and click - button
select it and press backspace, delete, or Z key
right-click it and choose Lift from context menu

remove a clip and the space it occupies causing all following clips on timeline to "ripple" to the left

select it and shift+backspace or shift+delete
select it and press X key
right-click it and choose Remove from context menu

remove the gap between clips: right-click and choose Remove from context menu
undo/redo integration
project/document integration - current project reflected in title bar, modified indicator and prompting to save a modified project before closing
saves as MLT XML
can be encoded

Not Done

(done) ~~inserting tracks between existing tracks~~
(done) ~~removing tracks~~
(done) ~~transitions~~
on-clip fader bars for audio and video levels
filter parameter key-framing
(done) ~~insert and overwrite edits~~
fancy editing modes like ~~ripple~~ (done), slip, slide, roll
(done) ~~splitting and joining clips~~
detach audio from video
(done) ~~locking tracks~~
multi-select clips
cut/copy/paste
(done) ~~saving what is in the playlist when saving a multitrack project~~ (When done, this will make the playlist like the "bin" in other programs.)
undo/redo integration for filters
dragging to trim should interactively crop the audio waveform (It is, however, cropped and redraw when released.)

Known Problems

(fixed) ~~does not work with GPU processing~~
(fixed) ~~menus appear at wrong location in window on OS X~~
(fixed) ~~drag-n-drop from clip viewer or playlist only works on Linux~~
(fixed) ~~moving a clip causes some waveforms to disappear~~
(improved) ~~sometimes undo/redo causes timeline corruption~~
sometimes thumbnails have incorrect aspect ratio
(fixed) You cannot dock ("put into a tab") the timeline with any other panels. In other words, do not try to stack the Filters panel along with the Timeline panel to switch between them using tabs. That does not work. If you accidentally do this, first un-tab everything so timeline is by itself. Then, using the View menu at the top, toggle the display of the timeline to hide and then show it. You can, however, place another panel at the bottom of the window around one of the edges of the timeline. For example, you can place the history view left of the timeline. We suggest docking the Filters panel in a tab at the top, left of the window along with Properties, Recent, and Playlist.

For the Technically Curious

We tried to implement this using MLT and Qt as much as possible with the least amount of new code and redundant state as possible. Meaning, it uses MLT objects for the document object model and its API to manipulate it. Then, we use the Qt model/view framework to add a non-stateful hierarchical Qt model wrapper/adapter for the MLT objects. This is then exposed in a QML-based timeline view that uses Quick Repeater elements with its support for data models and data binding. As like the QML filter UIs, the QML code for the timeline is loaded from the filesystem instead of resources embedded into the binary executable to facilitate customization, tinkering, and contribution. However, the Shotcut C++ APIs it uses are not yet documented, and Shotcut does not provide a QML/JS console or object inspector as found in some web browsers.

Beauty Is More Than Skin Deep

Tue, 01 Oct 2013 22:55:00 -0700

Shotcut recently received a major technology upgrade of some of its components. For the technical folks, it has been upgraded to Qt 5! This will make it faster and easier to develop filter control panels and the forthcoming timeline. You see, the engine for Shotcut - MLT - has hundreds of audio and video filters available. After making a few in Shotcut it became obvious we did not want to keep making them using the traditional method. In addition:

2 new custom UI themes/skins - light and dark - using clean, symbolic icons (in addition to the traditional "system" theme)
extended support for high DPI displays such as the Retina MacBook Pro - in particular, for the video viewport

Here comes the “more than skin deep part.” While everyone else has been working on getting video into HTML5, we have been working on getting HTML5 into video! The MLT plugin WebVfx uses Qt and WebKit technology - both of which have also been upgraded - to do just that. With this new version of Shotcut, WebVfx is getting more exposure, initially through 2 new filters:

Circular Frame: mainly a proof-of-concept, this demonstrates a filter whose processing is implemented in HTML5 canvas with a user interface implemented in QML to control its parameters.
Overlay HTML: just like it sounds. You can choose a HTML file on the file system and it will be rendered with a transparent background (if not set) over the video. Don't write HTML? There is a simple WYSIWYG HTML editor included. Did I mention it is simple? Feel free to try out some of the new HTML animation tools that are becoming available from Adobe, Google, Sencha, and others.

Unfortunately, we could not get all of this new stuff working correctly on Windows; so we had to disable support for GPU processing and the WebVfx integration on Windows at this time. The last Qt 4 version of Shotcut will remain available for download for a while.

Playlist Thumbnails

Tue, 09 Apr 2013 10:00:00 -0700

As of version 13.04.09 the playlist renders thumbnails of a shot’s in and out points. The following options are available in the playlist’s menu button:

Hidden
In Only - Large
In Only - Small (default)
In and Out - Left/Right (shown above)
In and Out - Top/Bottom (vertically stacked in above out)

We Have Filters

Sun, 10 Mar 2013 11:57:00 -0700

As of version 13.03.10, there are now several video filters available. Thanks to Movit and MLT, these filters run on the GPU using OpenGL Shading Language for speedy, high quality, 16-bit (per color component) linear float processing! There are also some CPU-based ones (8-bit integer with gamma); you switch between them by using the GPU Processing option in the Settings menu. This provides a convenient way to compare them. The GPU filter processing even works in conjunction with simultaneous SDI/HDI monitoring. Also, it works for background encoding jobs. The screenshot on the Shotcut homepage has been updated. Oh yeah, I almost forgot to mention that with the GPU-powered Color Grading filter, we now offer 3 way color wheels. :-)

Melted Server Integrated

Mon, 03 Dec 2012 10:15:00 -0800

The initial effort to integrate Shotcut with the Melted video server is now available since version 12.12.03.

What is Melted video server? Basically, it is an industrial-grade media player for broadcast/linear television channels. It was the original use case and application for the MLT framework, which is also the multimedia engine for Shotcut. For many of you this will be unimportant, which is why these new features are hidden under the View menu and not given prominent location on the main toolbar. However, for the folks who are interested in Melted, this represents the first publicly available multi-platform client!

This is just the initial, basic integration. There are a couple of simple enhancements planned for the near future:

Map the server's root directory of clips to the local or network file system so that you can easily preview and trim clips and then add them to a Melted unit's playlist.
When you open a unit that streams to the network, play the stream instead of just showing black.

Added Undo, Redo, and History View

Sun, 04 Nov 2012 21:03:00 -0800

Hello, as of version 12.11.04 there is support for Undo and Redo for the playlist. In addition, there is a History view to show the list of actions taken.

Support For Translations

Sat, 20 Oct 2012 11:49:00 -0700

Shotcut received its first submission for translation to the Czech language. So, I have added support to the code and build system to support the inclusion of languages as of version 12.10.20. This has been integrated and tested on Windows and Linux. I think there is still something I need to do for OS X with plists in the app bundle to support this.

If you want to translate Shotcut first please understand that Shotcut is young and under heavy development, and you should expect many changes over the next few years. Also, the project releases a new version almost daily, and there will not be periodic calls for translation updates; you would be responsible for periodic updates. With that said, please comment here or in the discussion forum if you want to make a translation.

Update: I have since setup a Transifex project to make it easier for people to make and submit translations.

Retina text rendering

Thu, 13 Sep 2012 08:50:00 -0700

As of version 12.09.13, the OS X build of Shotcut supports high resolution text rendering in the user interface on the new MacBook Pro with retina display. Unfortunately, it does not yet support double resolution icons, which is not too noticeable, but also extending the support to the embedded video is also still a challenge with Qt and OpenGL. We will revisit that later.

Playlists!

Mon, 10 Sep 2012 09:46:00 -0700

Available as of version 12.09.10.

Libre Graphics World Article

Mon, 13 Aug 2012 10:30:00 -0700

Libre Graphics World has just published an article about Shotcut. Thank you to Alexandre Prokoudine.

Screen recording enabled for Linux

Sun, 12 Aug 2012 10:48:00 -0700

I just realized that the nightly build did not include the options to support X11 screen and PulseAudio capture. So, I just enabled them, and they will be available starting with version 12.08.12.

Encoding now available!

Fri, 10 Aug 2012 06:15:00 -0700

Encoding is now implemented and available since version 12.08.10. It is still young and needs additional testing and tweaking; however, it basically works on all platforms. It also supports batch encoding, but currently the control over the queue is limited to simply canceling a running job (right-click a running job to open its context menu).

When you are playing a live source, encoding acts as a capture function. That is particularly handy for the Blackmagic Design SDI/HDMI input, but on Linux you can also use it for screen recording and webcam (V4L2) and audio recording.

In addition, it also supports a streaming output as an alternative to file output, but you really need to know what you are doing to take advantage of it at this time. I have pre-populated the stream URL field to something suitable for MPEG-2 Transport Stream; so, to use that, set the format to mpegts and choose codecs that mpegts supports: MPEG-1, MPEG-2, MPEG-4, H.264, AAC, AC-3, MP2, MP3.
