Release Notes

These are brief notes about known problems and feature additions. See News or the git log for more information.

Release 24.11.17
  • Fixed Convert stopped converting variable frame rate to constant (broke in v24.10).
  • Fixed filter in and out points when you resize transition by moving a clip (broke in v24.10).
  • Fixed Reframe loses its keyframes in Export (broke in v24.10).
  • Fixed moving a clip immediately after a transition beyond another clip stopped working (broke in v24.10).
  • Fixed Settings > Time Format > Timecode (Non-Drop Frame) for other non-integer frame rates such as 23.98 fps.
  • Fixed using Export > From > Marker with subtitles creates a bad output (broke in v24.08).
  • Fixed a video transition between sources with alpha channel is more translucent than expected.
  • Fixed a crash adding MLT XML As a Clip to a Timeline with a higher frame rate.
  • Fixed View > Resources > Convert negatively affects color if input is not HDR.
  • Fixed Export > Video > Aspect ratio immediately after you toggle Use hardware encoder.
  • Fixed possible crash on File > New or File > Close.
  • Fixed possible crash dragging a MLT XML file to Playlist of a new project/session.
  • Fixed changing Properties > Audio > Track > All to something else not working.
Release 24.10.29
  • Removed the Export > Video > Resample button. Now, there are simply ignorable inline warnings when making certain changes.
  • Added Subtitles > menu > Speech to Text:
    • This uses AI, but we did not make it. It uses a C++ port of OpenAI Whisper called whisper.cpp.
    • 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.
    • 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.
  • 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 can now adjust the transition duration.
    • Known bug: Using Undo after any of the above disconnects the transition from its adjacent clips and returns future operations around the transition to the old behavior.
    • The only way to get the old behavior is to first drag the transition to an empty area of another track. Ripple mode should be on if you want ripple delete. Or, simply accept the new behavior and adjust things as needed.
  • 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.
  • Fixed crash opening a project containing a subtitle track with no items.
  • 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 odd value for computed width in Reframe output video filter causes export to fail.
  • Fixed Reframe visual control can create odd-valued dimensions.
  • Fixed making a proxy video for a iPhone 16 Pro video containing spatial audio.
  • Fixed AVCHD video frame rate is double (could fix other formats).
  • 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.
  • Hide the Reframe video filter and button if GPU Effects is on.

  • Fixed keyframes are added when not intended in Color Grading video filter.
  • Fixed color in Export > Presets > stills > JPEG preset.
  • Fixed audio-only WMA file with DTS audio not playing.
  • Added Increase Text Size and Decrease Text Size to the context menu for Notes. 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.
Release 24.08.29

  • 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.
  • 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.

    • 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 sub-menu that tries to find similarly-named project files in the same folder create by Shotcut backup or recovery mechanisms.
  • Added Timeline > Selection > Group/Ungroup Ctrl+G. 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.
  • Changed Timeline > Detach Audio to automatically create a group.
  • 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.
  • The Jobs log viewer now updates automatically and scrolls to the end if it is left open while a job is running.

Release 23.11.29
  • 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 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 Timeline appears all white on Qt 6.6.
  • Fixed libvpx security vulnerability CVE-2023-5217.
  • Fixed libwebp security vulnerability CVE-2023-4863.
  • 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.
  • 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.
  • 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.
Release 23.09.29

    • Page (v23 default)
    • Smooth (old behavior)
  • Fixed some memory leaks and random crashes due to memory management.
  • Fixed overall speed of loading projects and editing that degraded in 2023 versions. (Existing projects must be saved after opening to upgrade them to benefit loading speed.)
  • 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).
  • Fixed some usability quirks with drag-n-drop and Ctrl multiple selection in the Playist > Icons view.
  • New and improved installer for Windows.
  • Improved the speed and memory of Timeline > Append, Insert, and Overwrite.

  • Fixed unable to save export job View XML with .mlt file name.
  • Changed Missing Files > Search to save the directory chosen.
  • Added --glaxnimate command line option to launch Glaxnimate instead (handy for Linux AppImage and Flatpak).
  • Fixed keyboard behavior of Help > Actions and Shortcuts on macOS.
  • Improved the quality of Settings > Proxy > Use Hardware Encoder on macOS.
Release 23.07.29
  • Fixed crash on startup on older Windows 10 computers that do not have Direct3D 11 (broke in v23.05).
  • 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.
  • 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 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 buttons in the Delete Filter Set confirm dialog are hidden if the name is long.
  • Fixed crash adding a GPU filter to Timeline > Output by not showing GPU filters for that selection.
  • Fixed top-field-first interlaced output.
  • 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.
Release 23.06.14
  • Fixed H.264 output when using Export > Use hardware encoder with NVIDIA (h264_nvenc)`.

  • Workaround for the Stabilize filter’s analysis job crashing on Windows.
    The analysis job still crashes at the end, but the data is still created and usable. So, go ahead and try to use the data regardless of the job’s failure.
  • Make adjusting image duration on timeline easier.
    Now, the Duration field in Properties adjusts the out point, and the actual duration is 10 minutes. This lets you add just a few seconds to the Timeline by default but then stretch or shrink the image clip on the timeline up to 10 minutes. If you need more than 10 minutes, add the clip to the track again.
