New Version 24.10: Whisper to a Scream

Oct 29, 2024

Version 24.10.29 is now available for DOWNLOAD!

Speech to Text

Shotcut gets its first AI based on OpenAI’s Whisper, courtesy of the whisper.cpp project. This is available through Subtitles > Speech to Text menu item or button: .

• Our builds include a basic model that has decent speed and accuracy but not a big size. (You can think of the model as the brain.)
• You can download a bigger and better better brain (model) in ggml format and configure it in the Speech to Text dialog, but it will be slower.
• The dialog creates two jobs that appear in the Jobs panel: one to export audio and another to convert to text.
• The results are added to the Subtitles panel as a new top-level Subtitle Track.
• Currently, the only GPU our build supports is Apple Silicon. Otherwise, it is heavily multi-threaded on the CPU.
• Known quirk: subtitle items sometimes start earlier than expected. Timing is provided by the model and tool, and we lack the skills and resources to improve this.
• Expect there to be occasional errors. Like humans and non-ideal conditions, it is not perfect. We will not take action on bug reports about some piece of audio not converting to the expected text.
• OpenAI has made some warnings about the usage of their Whisper models:

  In particular, we caution against using Whisper models to transcribe recordings of individuals taken without their consent…. We recommend against use in high-risk domains like decision-making contexts, where flaws in accuracy can lead to pronounced flaws in outcomes.

Transition Improvements

• Ripple Delete a transition restores the entirety of the clips included in the transition.
• Lift (non-ripple delete) a transition no longer leaves a gap; the gap is filled with the adjacent clips.
• Moving an adjacent clip away increases the transition duration instead of detaching and leaving a gap.

Other Improvements

• Removed the Export > Video > Resample button. Now, there are simply ignorable inline warnings when making certain changes.
• Added File > Show Project in Folder to menu.
• Added a decimals <number> option to numeric keywords in the GPS Text video filter.
• Changed Recent Projects to Projects: items in this view no longer disappear as Recent reaches its maximum length and old items are removed.
• Added a Remove action to the context menu in Projects.
• Hide the Reframe video filter and button if GPU Effects is on.
• Upgraded FFmpeg to version 7.1.

Fixes

• Fixed a crash doing when doing more than one Playlist > menu > Add Selected to Slideshow. In theory, this could fix other random crashes in Timeline.
• Fixed a crash opening a project containing a subtitle track with no items.
• Fixed odd value for computed width in Reframe output video filter causes export to fail.
• Fixed Reframe visual control can create odd-valued dimensions.
• Fixed AVCHD video frame rate is double (could fix other formats).
• Fixed making a proxy video for a iPhone 16 Pro video containing spatial audio.
• Fixed GPU filters paste below non-GPU filters.
• Fixed Slideshow Generator dialog is too tall with vertical video mode.
• Fixed GPS Offset would reset in GPS Text video filter.
• Fixed the maximum allowed Time in the Time Remap filter to prevent white frames.

New Version 24.08: Subtitles

Aug 29, 2024

Version 24.08.29 is now available for DOWNLOAD!

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.
• Fixed occasional audio pop/click with some media files especially with uncompressed audio.
• Fixed lag in Filters > search.
• Fixed a disabled Crop: Circle or Crop: Rectangle video filter becomes enabled when reselected.
• Fixed the hevc_toolbox hardware video encoder fails detection on some Intel Macs.
• Fixed file dialogs open slowly in the Linux AppImage.
• Fixed overriding Properties > Rotation on a proxy video whose default is not 0 exports with wrong rotation. 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 setting the audio language in Export > Other using alang=.
• 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.
• Upgraded MLT to version 7.26.0.

New Version 24.06

Jun 26, 2024

Version 24.06.26 is now available for DOWNLOAD!

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.
• Fixed View > Application Log > Previous not working after the first time.
• Fixed Properties > menu > View Bitrate hiding the first second.
• Upgraded Qt to version 6.7 on macOS, Windows, and Flatpak.
• Upgraded dav1d to version 1.4.2.
• Upgraded FFmpeg to version 7.0.
• Upgraded OpenCV to version 4.9.0.
• Upgraded VMAF to version 3.0.0.
