New Version 20.09.13: Pad Blur and Rich Text Video Filters
Sep 13, 2020
Version 20.09.13 is now available for DOWNLOAD!
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.
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).
