HTML5 Removal And Qt Upgrade

In the previous version, we announced the plan to remove the dated and deprecated HTML5 technology and related filters. Now, it has been completely removed in order to make it easier to upgrade our core UI library Qt. This major version upgrade includes many bug and security fixes as well as performance improvements. Linux users will notice a big improvement for high DPI display scale > 100%. This upgrade also makes it easier for non-team members to contribute.

  • Removed QtWebKit and WebVfx (HTML5 components) from all builds.
  • Upgraded Qt to version 5.15.1 on Linux and Windows and version 5.12.9 on macOS. As a result, the minimum macOS version is now 10.12.
  • Updated Linux build to a Ubuntu 18.04 base (glibc version 2.27).
  • Completely new Windows build based on msys2, and discontinued the 32-bit Windows build.
  • Migrated Windows and Linux builds to GitHub Actions, and automated builds of AppImage and snap for Linux.


  • Added Invert (reverse polarity) audio filter.
  • Added showing the job progress in Windows taskbar icon. (thanks @lolametro!)
  • Added Size, Position & Rotate > Zoom now works in any Size mode!
  • Added Scroll to Playhead on Zoom to Keyframes menu.
  • Added converting Text: HTML filters to Text: Rich. This does not retain full fidelity, but hopefully it retains the text.
  • Added using the H.264 hardware encoder if HEVC not available when Proxy > Use Hardware Encoder is on.
  • Added Scroll to Playhead on Zoom option to Timeline menu.
  • Added ability to change position in Size, Position & Rotate by dragging anywhere inside the rectangle while also holding Shift.
  • Added rectangle VUI help tips for various video filters.
  • Added keyboard shortcut for Center the Playhead: Ctrl+Shift+P.
  • Added keyboard shortcut for Scroll to Playhead on Zoom: Ctrl+Alt+P.
  • Added keyboard shortcut for rich text editor Paste Text Only: Ctr+Shift+V
  • Added common preset resolutions and aspect ratios to the Add Custom Video Mode dialog.


  • Improved image quality when using Size, Position & Rotate.
  • Improved Text: Rich filter export on Windows and Linux when display scale is fractional (e.g. 150%).
  • Improved the performance of the Fade In Video, Fade Out Video, and Brightness filters on multicore systems.
  • Changed Export > Codec > Dual pass to not write a video file for the first pass.
  • Removed “Shotcut” as default text in Text: Rich filter.
  • Reduced memory usage in Export with many clips.


  • Fixed a compatibility issue for some systems by downgrading FFmpeg to version 4.2 (regression in v20.09).
  • Improved the Timeline scrolling speed and smoothness (regression in v20.09).
  • Fixed time rulers hiding on vertical scroll in Timeline and Keyframes (regression in v20.09).
  • Fixed Crop: Rectangle > Corner radius not exactly the same as in version 20.07 (regression in v20.09).
  • Fixed Blur: Pad incorrect after splitting clip.
  • Fixed moving the cursor in filter fields may move playhead.
  • Fixed Filters allowed pasting filters when nothing selected.
  • Fixed saving projects to Dropbox on Windows leaves temporary files.
  • Fixed saving the current stock layout when switching to a custom layout.
  • Fixed progress dialog appears over the convert variable frame rate dialog when dragging to Timeline.
  • Fixed dropping file with comma in its name to Timeline.
  • Fixed delete keyframe button in Keyframes may remove keyframe for another parameter.

  • Fixed a crash dragging multiple clips to Timeline if some are variable frame rate.
  • Fixed the Blur: Pad filter appearing correctly if used that option in slideshow generator.
  • Fixed zooming in near end of timeline scrolls timeline backward.
  • Fixed deleting all text in Text: Rich filter changes font to very small black.
