Shotcut: v25.10.9 Release

Known Issues

• VA-API hardware encoder is broken on Linux
• The Flatpak cannot run things outside of its container; so, the HTML generator, Text to Speech, and Open With features will not work. The Flatpak release build will have those features removed.

Changes

• Fixed export with '&' in the file path or name.
• Fixed alpha channel decoding Ut Video with alpha channel.
• Fixed starting the Linux AppImage if AppImageLauncher is installed.
• Fixed Rejoin with Next Clip duplicates filters.
• The default for Settings > Time Format changed to Clock.
• Some under-the-hood changes in preparation for further end-to-end 10-bit processing on the CPU, but the user visible effect in this version is a different set of blending modes in track properties and the Blend Mode video filter.
• Changed Export > Search to include file name extension.
• Added a Text: Typewriter video filter.
• 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 reload--whether manual or automatic--every clip object based on this file.
• Added Text to Speech to Notes and Subtitles.
  • This uses Docker as 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.
• Added New > Screen Snapshot and Screen Recording on macOS and Windows only.
  • There is nothing in common built into all Linux desktops esp. that also works in Flatpak or Wayland.
  • These simply invoke screenshot on macOS and Snipping Tool on Windows.
  • On macOS, Screen Recording starts a Shotcut job in View > Jobs. To stop recording right-click the job and choose Stop This Job.
  • On Windows, it does not automatically open the capture file. 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.
  • It is not intended to be super integrated and comprehensive. Rather, think of them as simple reminders that your OS comes with some tools to do this if you do not want to bother to install something else.
• Added New > Image/Video from HTML.
  • This requires Google Chrome or Chromium.
  • I could not get Microsoft Edge to work even though it is based on Chromium; they changed the headless command line launch behavior enough such that is not clear how to get it working.
  • Please see the stock Presets for testing and examples.
  • The stock presets also demonstrate a template facility for up to 3 lines of text. Technically, you can substitute any piece of HTML, CSS, or JavaScript with this except it will not be obvious to a user that a line, for example, corresponds to a color or size and its special format.
  • 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 <kbd>V</kbd> button in the top right corner of the edit block to choose View Compiled before copying.
  • This does not support WebGL, and it might not support video either.
  • 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 input still in place. Once you add it to Playlist or Timeline, Properties now reflects the image or video and no longer shows the HTML inputs.
• Upgraded to FFmpeg 8.
• Upgraded librarues: SVT-AV1, libaom, dav1d, libvpx, libwebp, and whisper.cpp.
