shotcut

Windows on Arm

Hurrah for new Qualcomm Snapdragon X chip! Since there are now good Arm64 CPU systems for Windows, we added a native build for Windows on Arm64 CPU. Treat this as a beta. Known issues are there is no hardware encoder, and some audio filters are missing.

New Stuff

• Added SVT-AV1 encoder (faster non-hardware AV1 encoder).
• Added support for AVIF (AV1) images.
• Added a Drop Shadow video filter that uses the input alpha channel. (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.)
• Added a Vibrance video filter. This is similar to Saturation, but Vibrance is sensitive to the current saturation instead of adjusting all values equally as in saturation. This is especially helpful to prevent affecting skin tones.
• Added the Mid-Side Matrix audio filter for processing these kinds of microphones into proper stereo sound.
• Added Keyframes > Scrub While Dragging.
• Added Playlist > menu > Columns.
• Added support for DJI LRF (MP4) files as a proxy.

Fixes and Changes

• Improved handling for some variable frame rate videos. Now, Properties tries to show the file's target frame rate and extends the variable detection logic to include strange average frame rate values (what previous versions showed in Properties).
• Changed Playlist Tiles view mode to show Date instead of In/Start.
• Fixed using graphics (text, image, etc.) on upper video track with GPU Effects.
• Fixed an off-by-one frame bug in the duration for Glaxnimate animations.
• Fixed Undo does not work for time filters.
• Fixed spamming (Undo) History when using the timeline fade controls.
• Fixed preview color with GPU Effecs is inaccurate.
• Fixed Timeline > Select None does not clear the Filters panel or VUI.
• Fixed single click does not reset a multi-selection.
• Fixed Export > Codec > Quality hint not updated after changing Rate control.
• Fixed Properties > Proxy > Make does not regenerate if already exists.
• Fixed changing Properties (except Speed) affects clips on other tracks with Ripple All Tracks turned on.
• Fixed drag from Source and drop to Source changes Playlist.
• Fixed Automatically Add Tracks changes the current video track, which can cause unexpected behavior with Properties > Speed change, for example.
• Fixed files generated automatically in the project folder (.stab, .rawr, etc.) are incorrectly generated in the app data's autosave folder in the app session immediately after Shotcut recovers an auto-saved project.
• Fixed changing Properties can delete a timeline clip.
• Fixed selected filter changes unexpectedly by changing tabs or clicking filter categories.
• Fixed Properties > Audio > Track > All.
• Fixed the project folder when running an autosave-recovered session.
• Fixed Settings > Timeline > Auto Add Tracks creates too many tracks when drop multiple clips to Timeline.
• Fixed new Settings > Time Format not used in several places.

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.

• 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.

  This breaks support for Wayland on Ubuntu 23.04, which is a less important version than the other two.
  The combination of Wayland and Qt 6 seems impossible to handle universally in the portable/AppImage/Snap binary bundle. If installing a Qt 6 Wayland package does not work in your distro, some options are to login using an X session instead of Wayland or try the Flatpak.
• Fixed numerous audio filters missing on macOS/Intel (broke in v23.11).

• Upgraded AV1 decoder dav1d to version 1.4 and AV1 encoder libaom-av1 to version 3.8.0
• Upgraded rubberband audio pitch library to version 3.3.0

This highlight of this version is the addition of easing for keyframes: ease in, ease out, and ease in/out with different levels of acceleration and tricks like elastic and bounce. See the Easing Functions Cheat Sheet web page for an animated graphical overview of these behavior options.

Improvements

• Added Crop:Rectangle > Apply to Source button.
  This button is only enabled when the aspect ratio of the source media matches your project's Video Mode because it is impossible to include the black padding that Shotcut adds to a source. This feature is the primary way to simply "crop a video." You do not need to use the timeline for this. You can simply:

1. set Settings > Video Mode to Automatic,
2. open a video file,
3. add the Crop: Rectangle video filter,
4. adjust the rectangle control in the player,
5. click Apply to Source in the Filters panel,
6. choose Yes in the dialog asking to change the Video Mode, and
7. Export.

• Added Opacity to GPS Text, Text: Simple, and Timer filters.
• Improved performance of Timeline > Zoom.
• Added rectangular selection to Timeline.
• Added Settings > Timeline > Rectangle Select.
  This is on by default, and scrubbing with the mouse on the timeline requires clicking near the play head.
  When this is on, hold Shift to turn it off temporarily. When this is off, hold Shift to temporarily turn it on.
• Changed the Smooth keyframe type to avoid overshoots and cusps.
  This only applies to new projects made with this and future versions. Thus, the behavior of smooth keyframes made with an earlier version remains the same for compatibility reasons.
• Added Ease In, Ease Out, and Ease In/Out to Keyframes.
  This also changes the appearance of keyframes in the timeline view of Keyframes to make it more clear where the behavior applies - between keyframes. Remember this: when thinking about "in" or "out", for Shotcut "in" refers to the beginning of something - a clip, filter, or parameter between keyframes. And "out" refers to the end of something. So, this is not easing into a keyframe and easing out of a keyframe. Rather, it is easing into or out of the change/segment/span/tween of a parameter between keyframes.
• Added Properties > View Bitrate....
  If you have ever used the classic Bitrate Viewer for Windows and frustrated with the lack of updates or not available on your current OS, here you go.
• Added a Track Auto Fade Video filter. This can only be added to tracks and makes a dip to black or other color or fade in and out opacity for overlays to each clip.
• Changed Export > Codec and Audio to disable some options when a lossless-only or an intra-only codec is selected.
• Added Settings > Timeline > Automatically Add Tracks.
  The defaults for this is off because adding tracks increases memory usage. Also, it does not automatically add a track if nothing is in the Timeline as the timeline is optional in Shotcut. Also, it does not automatically add a track when you open a project with no empty tracks. It only adds tracks when you add something to the timeline or move a clip between tracks.
• Added a button in Filters to save a filter set and change the Copy checked filters button to not show a dialog.
• Added Filters > Set > Glow Intensity.
  This demonstrates how you can mix a filtered output with the input to reduce it.
  Also, change the Mask: From File > Treshold to do a side-by-side comparison with and without the filter.
• Added Split at Playhead back into the timeline clip context menu.
• Changed the Save option in the low memory dialog to perform a backup and save to prevent breaking projects.
• Added support for av1_nvenc NVIDIA AV1 hardware encoder on Windows and Linux.
• Upgraded MLT to version 7.22.0.

New Bugs

• Fixed honoring the "Do not show this anymore" checkbox in the Convert to Edit-friendly dialog (configuration key showConvertClipDialog) (broke in v23.09).

• Changed Export > Codec and Audio to disable some options when a lossless-only or an intra-only codec is selected.
• Added Settings > Timeline > Automatically Add Tracks.
  The defaults for this is off because adding tracks increases memory usage. Also, it does not automatically add a track if nothing is in the Timeline as the timeline is optional in Shotcut. Also, it does not automatically add a track when you open a project with no empty tracks. It only adds tracks when you add something to the timeline or move a clip between tracks.

This release has reliability and performance improvements plus some nice new things such as a batch convert tool and keyframes for color parameters.

This release has important bug fixes plus new audio filters to remedy an old problem.

New Bugs

• Fixed crash on startup on older Windows 10 computers that do not have Direct3D 11 (broke in v23.05).
• Fixed Timeline scrubbing and skimming accelerate too much (broke in v23.06).
• Fixed Stabilize analysis jobs not working on a speed-adjusted timeline clip (broke in v23.05).
• Fixed the visibility of the cursor in the Text: Rich filter's editor (broke in v23.05).
• Fixed the up and down cursor keys not working in some numeric fields (broke in v23.05).
• Fixed seeking on the new Speed: Forward Only and Speed: Forward & Reverse filters.
• Fixed the buttons in the Delete Filter Set confirm dialog are hidden if the name is long.
• Fixed the color level of RGB and RGBA sources (e.g. images) with GPU Effects.
• Fixed crash adding a GPU filter to Timeline > Output by not showing GPU filters for that selection.

Old Bugs

• Fixed shift-drag-drop from Windows Explorer to Playlist deletes the files! This is an old bug, and Shotcut is not deleting the files. But it accepts a move drop action for the purpose of reordering playlist items. However, doing so with a list of filenames makes Windows assume the receiving application did something appropriate with thes file and then... delete them on behalf of the app just to be sure?!? Smooth move. (Another Windows file manager Directory Opus does not exhibit this bad behavior.)
• Fixed another very old bug on Windows where sound does not follow the default output device, for example plugging headphones, until you restart the app. Please note that if you are using Settings > Audio Channels > 6 (5.1) after the default sound output changes, you will likely experience distortion in the audio playback until you restart the app.
• Added the --SDL_AUDIODRIVER command line option for Windows and Linux.
• Fixed appending to Playlist from clipboard with nothing yet opened in the Source player.
• Fixed the Export > Audio > Quality range for the aac codec.
• Fixed trying to drag a keyframe vertically may snap changing its horizontal position.
• Fixed clicking OK in a color dialog on Windows without changing anything resets the alpha to 255.
• Fixed top-field-first interlaced output.

Improvements

• Added Track Auto Fade and Track Seam audio filters. These filters address an old problem where clicks and pops may be heard in export when switching between clips due to discontinuities in the audio stream. A recommended technique was to add a 2 frame Fade Audio Out and Fade Audio in filters on clips. Track Auto Fade automates that. Track Seam works on a similar level but rather attempts to do a smoothing between outgoing and incoming samples around edit points. Both of these new filters may ONLY be added to individual tracks—audio or video.
• Added Transition type > Cut to the Slideshow Generator.
• Added Ctrl+Wheel (command on macOS) to numeric fields to increment and decrement by a larger amount.
• Updated Qt libraries to version 6.4.3.
• Updated libebur128 to version 1.2.6.
• Updated rubberband library to version 3.2.1.
• Updated MLT to version 7.18.0.

From beta to release candidate:

• Fixed the color level of RGB and RGBA sources (e.g. images) with GPU Effects.
• Fixed trying to drag a keyframe vertically may snap changing its horizontal position.
• Fixed clicking OK in a color dialog on Windows without changing anything resets the alpha to 255.
