New Version 24.08: Subtitles
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_toolboxhardware 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
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
autosavefolder 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.

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.
- Added changing Properties > Duration on image clips on the Timeline (behavior depends on Ripple similar to changing Properties > Speed on an audio/video clip).
Fixes and Changes

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

- 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_AUDIODRIVERcommand 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.txttoshotcut-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.
