The main announcement for this release is a major update to an important library
that Shotcut uses for the UI (user interface) called Qt.
There have 6 major releases and two LTS (long term support) releases since the
version we were using. The new version we are using is Qt 5.9.7, which is
LTS (5.9) and is quite stable given the number of revisions (.7). It is a little
faster as well. We did not upgrade to the latest LTS (5.12) in order to retain
compatibility with macOS 10.10 and 10.11, and we want to use the same Qt version
across platforms. (Linux Flatpak is an exception.) With our new Qt builds, we
added support for HTTPS, which extends to our HTML effects based on WebVfx
and QtWebKit. This will let custom HTML titles and effects that you make link
Added Offset to the Timer video filter.
Added Vertical HD 30 fps and Vertical HD 60 fps video modes.
Much of this release was based on contributions in the form of code, presets,
title templates, feedback, bug reports, and testing nightly builds or the beta.
Also, recently, we added a
page to the Web site.
Added Center Playhead option to the Timeline and Keyframes menus.

Added an automatic retry without Parallel processing when Export job fails.
Set the Save as type list on the Export File dialog on Windows when a

The new Mask: Apply filter makes it possible to mask filters without using
multiple tracks! Use Mask: Simple Shape or Mask: From File to start the
filter mask followed the video filters to be masked followed by Mask: Apply
to apply the mask to the filters in between. Filters before or after the mask
filters affect the entire video frame. One can still use Mask: Simple Shape
or the new Mask: From File to affect the alpha channel for multitrack
compositing as before.
Added View > Scopes > Video Histogram.
Added Preset to some more filters:
Added Preset and simple and advanced keyframes to the Balance and Pan audio filters.
Added a Levels video filter with simple and advanced keyframes!
Added Properties > Color Range for video clips.
Replace the Mask video filter with 3 new filters:
Mask: Simple Shape
Mask: From File
The new Mask: From File is a powerful new video filter offering 3 modes:
wipe transition (stock or custom)
Channel > Brightness from a video or image file (File > Custom…)
Channel > Alpha from a video or image file
Moreover, Threshold can be animated with simple or keyframes, which is
especially nice when used with luma-wipe image files (stock or custom). Not only
can you wipe on a filter but also you can use this as an alternative way to make
a wipe transition using multiple tracks (instead of same track transition).

unsupported is made a truly advanced option by hiding it. Now, one can only
enable it by manually changing the configuration file/registry. To make things
easier a New Project screen was added, most Export options are hidden behind an
