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 more modern with rounded corners in many places.
• New logo
• Upgraded FFmpeg to version 9.0

Full Changelog: v26.6.25...v26.7.16

External Monitor with a System Display

Three years ago, when we upgraded our UI library to a major new version, we lost support for using an additional system display as an external monitor. Many people were disappointed to lose that feature. Now, after a major change to the video plumbing, it is back!

The External Monitor submenu is moved from Settings to the top of the Player menu. It is incompatible with newly added Settings > Player > Use Old Video Output (provided just in case the new plumbing does not work).

The new plumbing also provides a way to preview HDR video except, for technology reasons, it must be shown in a separate window...

HDR Video Preview and Export

As a quick reminder for those unfamiliar: "HDR" means high dynamic range, not high definition resolution. It is about expanded color and light. A lot of phones and cameras are recording with this today, and many people are not aware until they try to edit and run into problems. Also, HDR game captures on computers is increasingly common. A year ago, we added very limited, hidden support for editing HDR video because, basically, we had no way to display it without a device from Blackmagic Design. Now, there is a way.

• Added Player > External Monitor > Preview Window (HDR) that can be made fullscreen.
  • It also works for SDR.
  • HDR requires a display properly configured with HDR, Native 10-bit CPU or Linear 10-bit GPU/CPU processing modes, and HDR video sources.
  • For HDR, only use filters tagged with #gpu or #10bit.
  • It does not appear to work on Linux, at least I have not been able to get it working.
  • Switching between PQ HDR (HDR10) and HLG HDR requires restarting the app.
  • The default shortcut to open or raise the preview window is Ctrl+`. It does not toggle between open and close because raise is more convenient.
  • You can move the window by clicking anywhere inside except the controls bar and dragging.
  • F toggles fullscreen and Esc also leaves fullscreen.
  • Incompatible with Use Old Video Output.
• Added Dynamic range to custom Video Mode and Timeline Properties.
  This offers SDR, which follows the colorspace, HLG HDR, and PQ HDR.
• At this time, Shotcut only supports converting log profile video to HDR with GPU processing mode and HLG HDR video mode.
  And it cannot convert between HDR formats or combine multiple HDR formats within a project.
• Added support for PQ HDR (HDR10) to External Monitor > DeckLink.
• Added support for HDR to Export (based on Video Mode and 10-bit processing mode).
• Added HDR10 metadata dialogs for External Monitor > DeckLink and Export > Codec.
  Export only embeds HDR10 metadata for the libx265 and libsvtav1 video codecs and no hardware encoders.
• TODO: Properties > Convert and View > Resources > Convert do not support 10-bit yet; that will be added in the next release.

External Plugins

We added limited support for external audio and video plugins.

"Limited" means it does not support a plugin's included UI, and our UI generator is new and experimental. That means you can only try it if you are an advanced user who knows how to supply a command line option to reveal the new UI generator. There are many mysterious effects, and uncertainty if things are working correctly. As a result, the user experience is not yet good enough with an increased risk of crash.

"External" means both effects included with Shotcut but not yet available in the UI or plugins that you install yourself to the standard, expected location for your OS.

OpenFX Image Effect Plugins

• Added a UI (--experimental not required) for NTSC-rs.

• Limited compatibility: not available, seems to do nothing, or makes the video black.

• No support for plugins that operate temporally or require multiple image/video inputs.

• No support for generators, transitions, or retimers.

• No support for the UI embedded in the plugin.

• No support for GPU technologies but multi-threaded CPU does work.

• Very limited testing. There are many plugins we have not tested especially commercial ones, and we know there are some that do not work.

• None are included with Shotcut.

• Looks for plugins in the standard folder for the operating system.

  OS	Path
  Linux	/usr/OFX/Plugins
  	/usr/local/OFX/Plugins
  macOS	/Library/OFX/Plugins
  	~/Library/OFX/Plugins
  Windows	C:\Program Files\Common Files\OFX\Plugins

VST2 and LV2 Audio Plugins

• Added a UI for Valhalla Supermassive.

• No support for the UI embedded in the plugin.

• No support for instruments.

• Very limited testing.

• None are included with Shotcut.

• Looks for plugins in the standard folder for the operating system.

  OS	Path
  Linux	/usr/local/lib/vst
  	/usr/lib/vst
  	/usr/lib64/vst
  macOS	/Library/Audio/Plug-Ins/VST
  	~/Library/Audio/Plug-Ins/VST
  Windows	C:\Program Files\Common Files\VST2
  	C:\Program Files\VSTPlugins
  	C:\Program Files (x86)\Common Files\VST2
  	C:\Program Files (x86)\VSTPlugins

Safe Mode and UI Generator

• Added menu item Settings > Leave Safe Mode.
  This appears if Shotcut crashes within 30 seconds upon startup, which restarts in a safe mode without external (OpenFX, VST2, LV2) plugins.
• Added --experimental command line option to try out the filter UI generator.
  This provides a Manage Add-on Filters dialog to search for effects included with Shotcut or external plugins. After choosing some to add-on, they become available in the regular Filters menu in the current as well as future sessions.

Other New Features

• Added Reduce Noise: Audio (RNNoise) filter. More info about RNNoise
• Added Settings > Display Method > Vulkan on Linux.
• Added Settings > Timeline > Create Transitions on Overlap to disable that feature.
• Added support for the .lot filename extension for Lottie animation handled by Glaxnimate.
• Added support to load custom filter UIs installed to App Data Directory > extensions > filters.
  If someone shares a custom or generated UI for an external effect/plugin that seems useful and safe, you can install it here to use it in your Shotcut without needing to use the --experimental mode.
  This can also be a place to add custom general purpose scripts by making a dummy filter. Use mlt_service: 'shape' as the dummy/no-op backend filter in the meta.qml. Soon we will add a proper scripts panel.
• Documented a scripting interface.

Changes

• Changed Linux Snap to use a desktop environment file dialog if possible.
• Changed the new Log Event shortcut to Shift+D because one conflicted with Remove Subtitle Item.
• Moved Declick Audio from the Time category to Audio in the filter menu.
• Upgraded MLT to version 7.40.0
• Upgraded FFmpeg to version 8.1.2

• Fixed 10-bit H.264 encoder fails with hardware encoding on.
  No H.264 hardware encoders support 10-bit; this change simply makes it use software encoding with x264.
• Fixed Export > Ogg Vorbis with Cover Art fails (no longer fails but our Ogg integration does not support cover art).
• Fixed Export > From > Marker using the Reframe output video filter with keyframes.
• Fixed some toolbar icons' tooltips not showing keyboard shortcut.
