Shotcut

What's Changed

See a nicely formatted page on the web site.

• Fixed security flaws in upgrade and Whisper downloads (failed HTTPS was retried over HTTP, certificate errors could be ignored, and a downloaded file could be used without a trusted digest).
• 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).
• Improved audio quality by removing a conversion to 16-bit integer and keeping the pipeline in 32-bit float.
• Fixed LV2 external audio plugins not loading on Windows (unless LV2_PATH environment var set explicitly).
• Fixed 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 Subtitles view shows incorrect duration (broke in version 26.8).
• Fixed moving Timeline clip next to another with snap while zoomed out may insert 1 blank frame.
• Fixed copy and pasting a Timeline transition corrupt audio in the pasted transition.
• Fixed window title bar missing on Linux with Settings > Display Method > Vulkan.
• Fixed marker unexpectedly deleted when moving a clip to the left with Ripple Markers on.
• Fixed keyframes on Timeline > Split after a transition.
• Fixed Export job may report failure even though file was completed successfully.
• Fixed some buffer overflow security issues in PGM/wipe reading in MLT and Set Equirectangular in Shotcut.
• Fixed projects deleted from disk still appear in Projects.
• Fixed Ctrl+Up and Ctrl+Down cannot change current track when Timeline loses focus.
• Fixed Player > External Monitor > DeckLink (and related such as UltraStudio) HDMI/SDI may deadlock.
• Fixed MLT XML nested clip's length (duration) not updated, now updates when selected but needs manual trim to increase clip.
• Fixed redundant context menu on text edit controls in filters on Windows (broke in v26.8).
• Fixed open project on a mounted CIFS/SMB share on Linux kernel 7.1 and above.
• Fixed possible crash when trying to add subtitle item in the last half second of the timeline.
• Hardened MP4 parsing in Set Equirectangular in Properties and export job context menu.
• Changed Settings > Leave Safe Mode to an always-present Allow External Plugins checkbox that defaults to off.

This helps prevent the problem that some VST2 plugins on Windows and macOS are causing startup and shutdown (including export) problems.

• Detect a stuck application startup to automatically disable external plugins.
• Added Automatic Audio Ducking for audio to timeline track Properties.
• Changed Adjust Clip Gain for timeline clips to require Ctrl+Alt (option+command on macOS) to drag.

This makes it safe from inadvertent changes while selecting and dragging clips. So, now that setting defaults on again. Also, a tooltip was added to the clip's audio line.

• Added volume control and audio level meter/indicator to Timeline track headers.

This effectively makes the track header column a mixing console without needing to clutter the UI with a new panel. The gain filter this adds to the track is keyframable.

• Added Timeline > Generate > Adjustment Clip. This is a dummy video clip that contributes no video.

Instead, its filters apply to the composite of all video tracks below it.

• Added application.triggerAction(name), multitrack.clipStart(), and timeline.split() functions for scripts.
• Added a context menu with Copy to Missing Files dialog and View > Resources.
• Improved the performance of the Timeline: moving clips to another track, zooming, undo for many operations (except for ripple move/trim).
• Improved the appearance of the user interface to be
