26.9.27
الأحدث عبر GitHub Releases 28 سبتمبر 2026## What's Changed
See a [nicely formatted page](https://www.shotcut.org/blog/new-release-26.9.27/) 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 more modern with rounded corners in many places.
- New logo
- Upgraded FFmpeg to version 9.0
