Settings > Preview Scaling > Use Hardware Decoder:
Enabled by default, except with NVIDIA on Linux.
Uses VA-API on Linux, Media Foundation on Windows, and Video Toolbox on macOS.
Only supports codecs your hardware can decode; automatically falls back to software decoding if needed.
May not provide a dramatic speed boost unless you use Linear 10-bit CPU processing mode or have a low-powered CPU.
Has limited impact on seeking and scrubbing—using proxies is still recommended for smooth editing.
Reduces CPU usage, which can help lower battery drain and keep your system cooler.
Not integrated with GPU processing mode via 0-copy.
Transferring uncompressed video between CPU and GPU RAM can be a bottleneck, so this feature is limited to preview scaling or 1080p-60fps (or lower) sources.
Export > Codec > Use hardware decoder:
Disabled by default, as it can sometimes increase export times.
No resolution or frame rate limits.
Can reduce CPU usage during export, which may be beneficial for some workflows.
(Tip: Avoid exporting videos on your lap for long periods!)
The setting is persistent and will be remembered between sessions and projects.
Feel free to test it on your system to see if it offers benefits for your specific hardware and workflow.
What's This:
This is contextual help! It lets you get assistance for a specific item in the user interface—just click the "What's This?" icon, then click on the UI element you want to learn about. Usually, this opens a web browser to the relevant documentation, but for some items like toolbar buttons, it may show a tooltip instead if more detailed documentation isn't available.
Comprehensive documentation is essential for this feature to be useful. Many users aren't aware that documentation exists, but it's now much more complete and accessible. The documentation is available on the website, and a PDF is generated automatically from the forum-wiki-based content. Additionally, the forum offers a Claude AI bot t

Fixed nesting MLT XML stopped working.
Fixed Screen Recording missing on Linux and macOS.
Fixed Stabilize video filter on macOS.

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 mo

Added New > Image/Video from HTML:
This requires Google Chrome or Chromium.
Please see the stock Presets for examples.
It defaults to a transparent background!
The stock presets also demonstrate a template facility for up to 3 lines of text. You can make your own templates by using %1, %2, or %3 as placeholders in the Body field.
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 V button in the top right corner of the edit block to choose View Compiled before copying.
This does not support WebGL or embedded video.
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 for revising if needed. Once you add it to Playlist or Timeline, Properties now reflects the image or video and no longer shows the HTML inputs.
Added Text to Speech to Notes and Subtitles:
This uses Docker 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 Windows, Screen Recording simply launches Windows' Snipping Tool provided by Microsoft. It does not

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 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

Added a Whisper.cpp (GGML) model downloader to the Speech to Text dialog.
A model is no longer included in the download and installation reducing their sizes.
Improved the System theme to follow the operating system palette on Windows (darker and more contrast), and improved its appearance on macOS dark mode.
Added Settings > Theme > System Fusion that combines the operating system palette with the monochrome, symbolic icons of the Fusion themes.Added an Outline video filter that uses the input alpha channel--useful with rich text or assets with a transparent background.
This means that, like Drop Shadow, it will not work as expected when used after a text filter on a video or image clip. Rather, you must use a text clip (transparent color generator with text filter) on an upper track.
Other New Features:
Added the ability to drag the waveform peak line to adjust audio gain.
Added Settings > Timeline > Adjust Clip Gain/Volume to turn off the above.
Added rolling an edit/trim to Timeline:
Hold Ctrl (command on macOS) while trimming to simultaneously trim the neighbor clip.
Added a Soft Focus filter set.
Added Audio/Video duration to the Slideshow Generator dialog, defaults to 4 hours.
This facilitates using Slideshow Generator to make transitions between everything when including both video and images. (It still respects the source duration and in & out points; duration here is a maximum.)
Surround Sound Mixing Improvements:
Added fader and surround balance to the Balance audio filter if channels > 2.
Added support for 4 channels in the Copy Channel audio filter.
Added Channels toggle buttons to many audio filters:
Band Pass
Compressor
Delay
Downmix
Equalizer: 3-Band
Equalizer: 15-Band
Equalizer: Parametric
Expander
Gain/Volume
High Pass
Low Pass
Limiter
Mute
Noise Gate
Notch
For example, now you can:
Copy stereo music to the rear channels and use the fader in the Balance filter to reduce its volume,
Downmix spoken word into the center channel and appl

Changes After Beta:
Fixed exporting projects containing only Generator clips on Windows (broke in v25.05).
Added Outline video filter that uses the input alpha channel, useful with rich text or assets with a transparent background. (This means that it will not work as expected when used after a text filter on a video clip; rather, you must use a text clip on an upper track.)
Fixed dropdown menus using Settings > Theme > System on Windows.
Improved the System theme to follow the operating system color mode/palette.
Added Settings > Theme > System Fusion that combines the operating system color mode/palette with the monochrome, symbolic icons of the Fusion themes.
Added a Soft Focus filter set.

Enhancements:
Added Ambisonic Encoder audio filter.
Added View > Scopes > Audio Vector.
Added View > Scopes > Audio Surround.
Added Settings > Time Format to affect everywhere that timecode is displayed or editable.
Added a indication to the on-video control for the Ambisonic Decoder audio filter.
Added Edit > Undo and Redo support for adding, removing, and changing Keyframes (work in progress) for the following filters:
Fade In Audio
Fade Out Audio
Gain / Volume
Brightness
Color Grading
Contrast
Fade In Video
Fade Out Video
Text: Rich
Size, Position & Rotate
White Balance
Added Apply Copied Filters to Timeline > menu > Edit and context menu that works with multiple selected clips.
Upgraded MLT to version 7.24.0.
