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).
Fixed color accuracy of lossless/Ut Video preset and use yuv422p format.
Fixed number of digits for seconds in the Timer video filter when using Format > MM:SS.SS.

Added 16:9, 9:16, and 1:1 aspect ratios for transition wipes.
Moved Properties > Reverse… from the overflow menu to a button.

When Reverse job completes, automatically open it and add it to the Playlist.
Start playback from the beginning if you play when the play head is at the end.
Improved speed of the Text and Timer video filters.
This version brings hardware encoding to macOS and VA-API encoding for Linux.
Meanwhile, the experimental GPU Effects mode, which was always unstable and
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
Advanced button, hardware encoding gets a checkbox, and a signed macOS build is
UPDATE: Version 18.09 has been
re-released (build 18.09.16)
to fix major new bugs with the Rotate and Scale, Size and
Position, Text, Chroma Key, Key Spill, and White Balance filters.
This release is packed with fixes and improvements in many areas!
Added Ripple support for moving clips including Ripple All Tracks.
When Ripple is on and you move a clip to the right, it now
ripples (pushes) all the clips to the right instead of making a transition
(including the Ripple All Tracks option).
Added Ctrl+R keyboard shortcut to toggle Timeline Ripple, Ctrl+Alt+R to toggle Ripple All Tracks, and Ctrl+Shift+R to toggle both.
Improved Snapping behavior on the Timeline.
Added Ctrl+P keyboard shortcut to toggle Snapping.
Added Reset Track Height (Ctrl+0) to the Timeline menu.
Added a Timer video filter.
Added support for negative rotation to the Rotate and Scale filter.
Added Shake 1 Second - Scaled and Shake 1 Second - Unscaled presets
to the Size and Position filter.
Added a Text clip to the Open Other dialog.

Improved closing Shotcut more reliably and the behavior of multiple shotcut
Fixed Undo beyond Remove Track may crash.
Fixed a crash when moving a clip after undoing a transition.
Fixed a crash loading project after some sequence of inserting and removing tracks.
Fixed a crash loading an image with the wrong filename extension.
Fixed OS audio device changes may cause Shotcut to hang.
Fixed crash dragging simple keyframes beyond the edges of the clip.
The 32-bit Windows build can use more memory to reduce risk of crash:
3 GiB on 32-bit Windows and 4 GiB on 64-bit Windows.
Fixed a crash applying an image transform filter to an image with alpha
channel (PNG, SVG).
Improved behavior of opening WebP images.
Fixed advanced keyframes for the Size and Position filter.
Fixed inserted and then hidden video tracks become audio tracks after
re-opening the project.
Fixed changing Video Mode from Automatic to something else with
Fixed moving a transition to another track leaves a hidden clip on the old track.
Fixed trimming the out point of a timeline clip may change the in point of
the following clip.
Fixed Properties > Speed, Convert, Reverse, and
More Information does not work sometimes after reloading a project.
Fixed reliability of changing size and position fields with keyframes
in Size and Position and Text filters.
Fixed trimming outward with Ripple All Tracks moved clips on other tracks
in the wrong direction.
Fixed audio waveforms still appear on muted tracks after adding a track.
Fixed dragging clips to the Timeline stops working.
Fixed edges of text with the Text filter may get cut off (clipped).

Fixed reducing the Frame/sec in Export causes timing errors in the output.
Fixed image scaling interpolation method when not using a transform filter.
Removed the Compositing toggle icon from the Timeline track head. Now,
it is located in the track Properties as Blend mode with a None option.
In the 3D Text filter, replaced the Droid fonts with Liberation due to an
Well, to be honest, there is not much speed improvement. Most of the improvement
comes from a fix to prevent an incomplete shutdown. In the case of the 32-bit
Windows build, since more memory can be accessed now, we have removed some of
(not all) multi-threading limits.
Improved the performance of changing filter parameters and scrubbing.
Limit the number of background thumbnail and waveform generation threads to 4.
Prevent trying to generate audio levels for waveforms for still images and
other silent sources.
