Replace the Mask video filter with 3 new filters:

• Mask: Simple Shape
• Mask: From File
• Mask: Apply

The new Mask: Apply filter makes it possible to mask filters without using multiple tracks! Use Mask: Simple Shape or Mask: From File to start the filter mask followed the video filters to be masked followed by Mask: Apply to apply the mask to the filters in between. Filters before or after the mask filters affect the entire video frame. One can still use Mask: Simple Shape or Mask: From File to affect the alpha channel for multitrack compositing as before. This makes them compatible with existing information and tutorials that suggest using multiple tracks as well as enabling collage/montage or transition effects when the tracks do not use the same clip.

The new Mask: From File is a powerful new video filter offering 3 modes:

• Wipe transition (stock or custom)
• Channel > Brightness from a video or image file (File > Custom...)
• Channel > Alpha from a video or image file. Moreover, Threshold can be animated with simple or keyframes, which is especially nice when used with luma-wipe image files (stock or custom). Not only can you wipe on a masked filter but also you can use this as an alternative way to make a wipe transition using multiple tracks (instead of same track transition).

What's New

Subtitles

• Added View > Subtitles.
• Added Subtitle Burn In video filter (only works on Output track).

The Subtitles panel can be used to add subtitles to a project. Subtitles can only be added to the Timeline. They can not be added to the playlist or clips. We recommend to save subtitle editing until the timeline editing is complete because moving or cutting clips on the timeline will break the subtitle synchronization.

To start editing subtitles, click the "add" button and give the subtitle track and name and language. After the subtitle track is created the subtitle track area will appear in the timeline above the top video track. Multiple subtitle tracks can be added. But only the currently selected subtitle track is shown in the Subtitle Panel and the Timeline.

Click the "Add subtitle" button to make a new subtitle item at the cursor position. Then type in the "Current" text area to add the text.

Subtitles can also be imported. Supported subtitle import formats include: SRT, VTT, ASS, and SSA. Subtitles are imported at the current cursor position. So be sure to place the cursor before importing subtitles from a file.

Export

Subtitles can be exported to a file. Subtitles are exported in SRT format.

When exporting a Shotcut project, subtitles will be embedded in the output file if the file format supports it. Formats that commonly support subtitles include MKV, MOV, and MP4. You can disable this using the checkbox at the bottom of the Export > Other tab. You can also enter the text sn=1 in the other box to disable them.

Subtitle Burn In Video Filter

The Subtitle Burn In filter can only be added to the Output track. The filter allows you to select an existing subtitle track, and overlay the subtitle text on the project video.

Other Changes and Fixes

• Added a Power (W) ( #gps_power#) field to the GPS Text video filter.
• Now Enter or Return in Filters > search changes focus to the search results.
• Now Up or Down in Help > Actions and Shortcuts > search changes focus to the search results.
• Changed the Softness to 0 in the Obscure With Blur and Obscure With Mosaic filter sets.
• Fixed the Linux portable, AppImage, and Snap fail to launch on some systems (e.g. Ubuntu 24.04) with Qt 6 and Wayland.

• This bug affected the creation of the proxy and thus requires making a new proxy, which is easier said than done on Windows due to file locking. Properties > Proxy > Disable Proxy on the affected clips is a workaround if you do not turn off proxy completely.
• Fixed Properties > Proxy > Make Proxy does not override a DJI- or GoPro-provided proxy video.
• Fixed 59.94 fps in Matroska falsely identified as variable frame rate (broke in v24.06).
• Fixed mono audio assets not playing through both stereo channels (broken in v24.06).
• Fixed Open Other > Audio/Video Device > Video Input on macOS (broke in v24.06).
• Fixed spinboxes on Settings > Theme > System on Windows takes too much space from the numeric field (broke in v24.06).
• Fixed many audio filters missing for Windows on Arm computers (broke in v24.06).

• Fixed right Alt key (AltGr) for text input in some languages instead keyboard shortcuts/actions in Windows.
• Fixed the Convert dialog when dropping hangs Windows Explorer until the dialog is closed.
• Fixed Add Keyframe at Playhead for some filters, for example Color Grading.
• Fixed enabling keyframes in Color Grading adds 2 keyframes.
• Fixed the modal font dialog on Linux can be behind main window making Shotcut not responsive.

Previous Release Notes:

Ambisonic Audio

Ambisonic spatial (spherical) audio is often used with 360° video whether output as spherical or reframed to a rectangle. Adding support for Ambisonic facilitates 360° video workflows with Shotcut.

But also the new Ambisonic Decoder audio filter is part of an affordable, simple way to record (e.g. GoPro MAX, Zoom H3-VR) Ambisonic audio and convert it to 5.1 surround. FYI, YouTube supports 5.1 surround on most TV-oriented devices (smart TVs, streaming boxes, game consoles). And Windows has something called Sonic to listen to surround through headphones. The new filter can also be used to listen to Ambisonic through headphones (binaural), to rotate the sound when you rotate spherical video, and to pan stereo or surround audio output for reframed 360° video. For example:

• Added Settings > Audio Channels > 4 (quad/Ambisonics).
• Added Ambisonic Decoder audio filter that converts to binaural, stereo, quad, Ambisonic, or 5.1 surround. When Ambisonic mode is chosen, it is an Ambisonic panner.
• Added Ambisonic metadata to Set Equirectangular if there is a track with 4 audio channels.
• Added Copy Parameters to 360 video filters to use with Ambisonic Decoder > Paste Parameters.
• Shotcut only supports first order Ambisonics at this time.

More New Stuff

• Added support for AMD AV1 hardware encoder on Windows (av1_amf) and Linux (av1_vaapi).
• Added automatic vertical scrolling to Timeline when moving a track.
• Added changing Properties > Duration on image clips on the Timeline (behavior depends on Ripple similar to changing Properties > Speed on an audio/video clip).

Fixes and Changes

• Upgraded macOS and Windows to Qt version 6.5.3, which changes the mininum macOS version to 11.
• Stop automatically grouping audio/video clips when Detach Audio (changed in v24.01).
• Improved selection in Timeline after various operations.
• Improved behavior changing Properties > Speed with Timeline > Ripple on.
• Improved the speed of opening a timeline project.
• Fixed Filters > + > Sets adds audio filters in reverse order (broke in v24.01).
• Fixed Properties > Convert HLG HDR to to Rec. 709 SDR is not tone-mapping (broke in v23.09).
• Fixed distortion caused by Mixdown audio filter.
• Fixed Normalize: One Pass audio filter maximizing levels at start of playback.
• Fixed old custom presets in text and timer video filters load with 0% opacity.
• Fixed Loop Selection on the last clip of Timeline not looping.
• Fixed Enter Full Screen and Preferences shortcuts on macOS.
• Fixed problematic filename characters in Settings > Video Mode > Custom Add.
• Fixed disabling the last audio or video filter when there is a time filter in Filters.
• Fixed File > Exit is slow or hangs if a job in Jobs is paused.
• Fixed Wave video filter distorts if Settings > Preview Scaling is on.
• Fixed incorrect gamma in preview player and File > Export > Frame when GPU Effects is on.
