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 convert dialog for variable frame rate never appears if dragged directly to non-empty playlist or timeline.
  • 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.
  • Fixed editor toolbar in Text: Rich filter usually overlays the text by default.

New Version 20.09.13: Pad Blur and Rich Text Video Filters

Version 20.09.13 is now available for DOWNLOAD!

Security Notice

All users are encouraged to upgrade to address a security vulnerability (CVE-2020-24619) in Shotcut’s check for a new version. In previous versions it was not using a secure network connection making it is possible for an attacker to change the URL to the web page containing the release notes and download link. That has been fixed in this version.

HTML5 Deprecation

Shotcut’s HTML5-based filters – including non-obvious video filters such as Crop: Rectangle in previous versions – were based on an old technology (QtWebKit) that we decided to remove. The technology is no longer officially supported by its founding organization and hinders our ability to upgrade more important technology. Moreover, there were some lingering stability bugs related to its integration that are very difficult to fix. In the previous version, some filters were marked as “DEPRECATED” as a result of this decision, namely Text: HTML, but not Crop: Rectangle, Crop: Circle, and Choppy. These were rewritten for this version. This new version automatically converts the Choppy, Crop: Circle, and Crop: Rectangle video filters in an existing project to their new replacements. Also, we added a new video filter named Text: Rich. It is not as capable as the old Text: HTML, but it should be easier to use and manage while being more reliable. The deprecated HTML-based filters are still included in this version, but now they are hidden. They will appear only when loading old projects that include them. This provides a transition to the next version that actually removes these filters: You can load an old project using the deprecated filters and replace or remove them.


Blur: Pad Video Filter

This is a new useful alternative to cropping to remove black bars from images or videos whose aspect ratio does not match the project. It is available in the slideshow generator as Pad Blur.

Text: Rich Video Filter

The rich text editor writes directly on the video preview, has a floating toolbar, and saves itself into the project file with no external HTML files to manage.

New Stock Layouts with Quick Switcher

  • Replaced View > Layout > Timeline Project with new, better Logging, Editing, FX, Color, Audio, and Player stock (pre-defined) layouts.
  • The current layout is saved automatically for each stock layout if selected, and Restore Default Layout is different for each stock layout.
  • Added a workspace layout switcher to the main toolbar for the new stock workspace layouts. Shotcut has had a named layout system and switching in the View menu for a while now, but the stock layouts were lacking imagination. Taking inspiration from some other tools, we add new ones

Other New Things

  • Added Zoom to fit icons to the Timeline and Keyframes toolbars. Thanks to @Namna for this contribution.
  • Added a VUI to the 360: Transform video filter to adjust parameters by dragging inside the player.
  • Added Set Equirectangular Projection… to the Jobs menu for a successful export job. This is used to add metadata to a video file to indicate it is 360॰ video in the equirectangular projection as required by most players and web services. We thank Varol Okan for the code we used to add this.


  • Improved the performance of the Timeline especially with projects over one hour long.
  • Changed Size and Position to Size, Position & Rotate and made Rotate and Scale hidden (only appears in old projects).
  • Replaced Choppy, Crop: Circle, and Crop: Rectangle filters with new versions that do not use HTML through WebVfx, which was deprecated in version 20.06.28.
  • Changed the Rutt-Etra-Izer, Swirl, and Text: 3D filters to be hidden since they are deprecated (still loads in old projects).
  • Changed the video track hidden icon on the System theme to be more clear and obvious.
  • Show an error dialog on startup if the frei0r plugins are not installed (only affects Linux distribution packages).
