New Version 23.07: Never Say Never
Version 23.07.29 is now available for DOWNLOAD!
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_AUDIODRIVERcommand 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
aaccodec. - 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.
New Version 23.06
Version 23.06.14 is now available for DOWNLOAD!
This release is mainly a collection of desirable bug fixes.
New Bugs
- Fixed H.264 output when using Export > Use hardware encoder with NVIDIA (
h264_nvenc). (Note: please avoid changing Codec > B frames higher than 0.) - Fixed file dialogs in filters crash Shotcut in Linux AppImage or on KDE.
- Fixed crash in Text: Rich > File > Open when choosing a text file.
- Fixed crash changing Video Mode with Count generator with GPU Effects on.
- Fixed crash when trying to Open MLT XML as Clip (nest project) with GPU Effects on.
- Fixed loading JPEG images over 32 megapixels.
- Fixed player not working if Settings > Player > External Monitor was used in a previous version.
- Fixed Timeline > Replace on a clip breaks some of its video filters.
- Fixed Keyframes > Add Keyframe in the Mask: Simple Shape filter.
- Fixed changing Keyframe Type or a keyframe’s time position in the Mask: Simple Shape filter.
Old Bugs
- Fixed custom keyboard shortcuts for actions in the Timeline or Keyframes context (right-click) menu.
- Fixed Properties > Copy Fill File Path uses incorrect directory separator on Windows.
- Fixed chroma bleeding on some (e.g. Ut Video) interlaced 4:2:0 files.
Improvements
- Improved the smoothness of fast forward (up to 64x) playback.
- Improved Timeline performance and automatic scrolling.
Release 23.05 Updated to 23.05.14
The latest release 23.05 has been updated to a new version 23.05.14 to restore Settings > Theme and fix several major new bugs.
New Version 23.05
Version 23.05.14 is now available for DOWNLOAD!
Qt 6
Qt is the main UI and app library (separate from the media engine) that Shotcut uses. This is the first major upgrade of it since Shotcut started over 10 years ago with Qt 5! (Some interim upgrades did feel major tho.) It was a lot of work, but as a result:
- The Windows version now directly uses Direct3D 11 instead of OpenGL (or OpenGL converted to Direct3D) for drawing portions of the UI: Timeline, Keyframes, Filters, and the video player. This is faster, and we hope it improves compatibility.
- The Windows version improves support for fractional display scaling in the system settings (e.g. 125% or 150%).
- The macOS version now directly uses Metal (Apple’s GPU tech) instead of OpenGL for drawing portions of the UI (see above). It is faster.
- The macOS app is now universal: compatible with both Intel and Apple Silicon CPUs (M1/M2) in the same app.
- Some fixes for commonly reported Linux bugs like some images not rendering, visual controls not showing, and OpenSSL 3 compatibility. This also ought to improve things on Wayland.
- There is now an ARM64 build of the Flatpak for Linux (but none of the core developers currently has a Linux/ARM system for testing and support).
Performance Improvements
Besides the performance improvements from Qt 6 above:
- Some timeline optimization.
- Additional multi-threading in audio/video file reading.
- Faster preview for most video clips without filters.
GPU Effects
Settings > GPU Effects is back! We made several big fixes to improve its stability. Decoupling it from the OpenGL used for the UI and video display also helps. If you think its performance is not so great try it with Preview Scaling. GPU effects’ performance improvement mainly comes on systems with weak CPUs, with certain filters like Scale & Position, and when stacking filters and video tracks. It also works best when using only GPU filters.
- GPU effects is not just about performance but also quality since it does all processing in linear color, which gives optimally colored blending and interpolation.
- End-to-end support for 10-bit! For this to work, on 10-bit sources use only GPU filters. Nothing prevents you from adding CPU filters, but that will introduce an 8-bit down- and up-conversion into the pipeline. To add text, use a text clip using Open Other > Text as that is not a 10-bit video source.
- Searching in Filters on “gpu” shows only/all GPU filters.
- All previous limitations are removed and working now: text filters, video scopes, stabilization.
- The Blend Mode video filter and track Properties option is not available because it is not yet implemented.
- Rotation is not available in the Size & Position filter because that is not implemented yet.
Motion Tracker Video Filter
- Added a Motion Tracker video filter. This is required to use motion tracking. It only does the preview and analysis and is not intended to include effects but rather drive other video filters…
- Added a Load Keyframes from Motion Tracker button to the following filters:
- Corner Pin
- Crop: Rectangle
- GPS Text
- Mask: Simple Shape
- Size, Position & Rotate
- Size & Position (GPU)
- Spot Remover
- Text: Rich
- Text: Simple
- Timer
- The Motion Tracker can be on a different clip than the clip with the above filters.
- The dialog only shows Motion Trackers that have successfully completed analysis.
- Click Reset in the dialog to remove the keyframes added by motion tracker and restore the state of these parameters to before motion tracking.
- Clicking Apply in the dialog more than once automatically resets the affected parameters before adding new keyframes; so, you do not need to reset manually between changes.
- You can edit the added keyframes, but if you reapply the motion tracker your changes are discarded.
- To change the initial position of something after applying tracking you should Reset, make changes, and then Apply again.
- Disable the Motion Tracker when your changes and its analysis are done (or turn off its preview). I do not recommend removing this filter when you are done loading keyframes because if you need to make an adjustment, this filter must still be available to list it in the dialog and get its tracking data.
More New Features!
- Added new time filters: Speed: Forward Only and Speed: Forward & Reverse. These are usually friendlier to use than Time Remap. The forward only version does not usually require converting the clip first unlike Time Remap and Speed: Forward & Reverse.
- Added saving and loading filter sets. A filter set is a collection of filters. The copy and paste buttons in the Filters panel open new Copy Filters and Paste Filters dialogs. When copying filters, you can optionally give it a name, in which case it will be saved to use not only in the current project but also all projects and sessions. Giving it a name still also puts it on the system clipboard. When pasting filters, you can choose to paste from the clipboard or a saved filter set. A few examples are included: Obscure With Blur, Obscure With Mosaic, Text Simple with Gradient Back.
- Added an Add To Timeline button to many things in the Open Other menu/dialog. That usually saves a couple of steps.
- Added a visual rectangle control to the Mask: Simple Shape filter.
- Holding Shift while dragging a point in the Corner Pin filter moves all corners together.
- Added faster and better quality YADIF deinterlacer plus addition of BWDIF deinterlacer.
- Added 10-bit export presets under the “ten_bit” category.
- Added support for Intel (“qsv”) AV1 and VP9 hardware encoders on Windows including 10-bit for AV1.
Fixes and General Improvements
- Less audio crackling in exports when audio source is not 48000 Hz sample rate.
- Less audio crackling upon start of playback in preview.
- Upgraded Glaxnimate to version 0.5.3, which fixes some bugs and can animate motion along a drawn path.
- Upgraded FFmpeg to latest version 6.
- Upgraded MLT to latest version 7.16.0.
- Upgrade AV1 codecs to latest versions.
- Stabilize and Normalize: Two Pass on a timeline clip is faster.
- The Lens Correction video filter is back.
- Added Settings > Language > Hebrew.
- Open Other > Text now has a Rich option.
- Changed File > Export > Video and its shortcut to be the same as clicking Export > Export File.
- Fixed seeking on raw FLAC audio files.
- Fixed Record Audio breaks the state of the player’s mute toggle when you unmute the Shotcut audio during recording.
- Fixed using the mouse wheel to scroll the timeline horizontally on macOS and Linux.
- Fixed image padding not transparent during a transition.
- Added low disk space warnings to the Properties > Convert and Reverse actions.
- Fixed loading projects made with version before 19.06 using comma for decimal symbol.
- Fixed chroma bleeding for interlaced YUV 4:2:0 video sources.
- Fixed Shotcut became very slow if something wrong and very large was saved to Recent. Shotcut no longer saves recent file names to the main configuration file, which is the Registry on Windows. It now saves to a
recent.initext file in its app data directory and limits the maximum size of any entry.
Drawbacks and Limitations
- Settings > Player > External Monitor with a system monitor (not Blackmagic peripheral) is no longer available.
- Export progress no longer shows on the Windows taskbar icon.
- The minimum version for Windows is now Windows 10. Older systems can continue to use version 22.12.
- The minimum version of our non-Flatpak Linux binaries is now based on Ubuntu 20.04 LTS, which uses glibc 2.31. This is due to modern C++ requirements in dependencies, and bundling libstdc++ can break non-bundled system components. Previously, it was based on Ubuntu 18.04 LTS, whose support period ended in April, 2023. Older systems can continue to use version 22.12, or maybe the Flatpak will work.
