Version 26.8.1

Elements 🔥
Added Elements panel to the File > New and View menus and the Generate buttons.
This is a very slim (22MB) stock asset library: emoji stickers, sounds, overlay transitions, animated text, graphics.
The content licenses are royalty free, including commercial, and do not require attribution:

Emojis: Open Font License 1.1
Sounds: The Sonniss #GameAudioGDC Bundle Licensing Agreement
Text, Transitions, Graphics: Lottie Simple License
Changes
Added Settings > Graphics Adapter for Windows and Linux (only if multiple GPUs).
Added Shake video filter.
First generated UI to be shared and officially adopted.
The --experimental UI generator now also generates a meta.qml.
(See View > Application Log to get the temp file names to copy and share these files.)
Improved appearance of tabs and Subtitles in Fusion Dark and Fusion Light themes.
Fixes
Fixed opening a .mlt project file from a file manager on macOS (broke in v26.6).
Fixed corrupt color in dissolve transitions with Settings > Processing Mode > Linear 10-bit CPU.
Fixed the new Reduce Noise: Audio (RNNoise) when the export audio sample rate is not 48000 Hz.
Fixed off-by-one frame errors in subtitle bar in Timeline and Subtitle Burn In video filter.
Fixed all builds missing support for VST2 and LV2 audio plugins.
Now install and try the Valhalla Supermassive VST plugin.
Fixed a libGLESv2.dll warning on startup on some Windows systems.
Fixed Motion Tracker keyframes not applying after save/reload.
Fixed manual override QSG_RHI_BACKEND environment variable on Windows.
Fixed Properties > Convert & View > Resources > Convert to keep 10-bit video as 10-bit when using 10-bit processing modes.
Fixed the Crop: Source filter with Preview Scaling and hardware decoder.
Fixed proxy video generated for rotated video (Properties > Rotation) not preserving rotation.

Version 26.7.30

Version 26.1

Other New Features
Added converting a project between GPU & CPU processing modes.
Added the Blend Mode filter and track option for the Linear 10-bit GPU/CPU processing mode.
Increased the maximum resolution in Video Mode and Export to 8640 for 8K VR180 video.
Added Settings > Language > Chinese (Simplified).
Changes
Improved the appearance of outline in the text filters: Text: Simple, Typewriter, GPS Text, Subtitle Burn In and Timer.
Changed bulk proxy generation (when you switch Settings > Proxy > Use Proxy ON) to update clips.
(Previously, you had to turn proxy mode off and back on again to start using the proxies. That requires reloading the project each time, which was a real drag.)
Changed Timeline > Add Generator and New Generator > Add To Timeline to not seek.
This leaves the playhead over the clip it just added to facilitate preview and reduce steps.
Changed simple keyframe defaults in Mask: From File filter to be more convenient for multi-track transitions.
Fixes
Fixed Brightness filter with a reduced level is different when there was clip with transparency above it (broke in v25.12).
Fixed Timeline > Record Audio would always reset the selected audio device and require re-selection (broke in v25.12).
Fixed the Mask: Apply video filter in 10-bit processing modes (incomplete in v25.12).
Fixed a crash in the scrub-bar on a very long playlist.
Improved the reliability of opening URLs (Help menu), Show In Folder, Open With in the Linux AppImage/portable/Snap.
Fixed app not responding while enqueuing very many proxy jobs.
Fixed Previous/Next in Subtitles may be unreadable on some themes and OS.
Fixed reading the alpha channel in 12-bit ProRes with alpha.
Fixed the Halftone video filter was not copying input alpha channel.
Fixed it was possible to use Split on a locked track in Timeline.

Version 25.12.31

2025-12-31

Version 25.12.30

2025-12-31
Higher Bit Depth: 10-bit Video CPU Pipeline
What is "bit depth?" That is the number of colors or video brightness levels. 8-bit has only 256 values per color component, for example, red/green/blue. 10 bits has 1024 levels. Previously, 10-bit video sources were only partially supported using GPU Effects and only GPU filters. Without GPU Effects (CPU), in order to stay in thee 10 bit space, you could only use filters with the #10bit tag but no transitions or track blending/compositing. Now, we have ported many CPU video effects to support 10- and 12-bit video sources including transitions and track blending. Also, the #10bit CPU video filters also work properly with the experimental GPU processing. Not all of the video CPU filters have been converted; many of them come through another software project that does not support it. However, we were able to convert many for this release or at least mark them as safe for a 10-bit project.

Higher Image Quality: Linear Color Processing
Any mixing of pixels with a color space's gamma is not ideal, can cause color distortions, and is technically incorrect. This pixel mixing occurs whenever images interpolated, for example scaling, blurring, and sub-pixel positioning, as well as with track blending/composition. Previously, only GPU Effects and video filters in the GPU category operated in linear color. Now, there is an option to use it outside of the GPU processing. But when using the GPU, the handoff of the video from GPU to CPU now stays in the linear color transfer.

There is a new sub-menu in Settings > Processing Mode with options:

Native 8-bit CPU (fast, flexible)
Native 10-bit CPU (slower, better)
Linear 10-bit CPU (slowest, best)
Linear 10-bit GPU/CPU (Experimental)
Non-linear "native" options are still included because there is a signficant performance decrease when using linear (more conversions). We have a plan to improve performance for the next release. 8-bit is still included because it is more "flexible" by including more video filters. Of course, you can use an 8-bit video filter in a 10-bit, but the quality of the video clip or track will suffer a reduction in bit depth.

Other New Features
