Version 18.12 is now available for DOWNLOAD!
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.
New Features
- Added View > Scopes > Video Histogram.
- Added Preset to some more filters:
- Audio Gain/Volume
- Blur
- Brightness
- Opacity
- 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
- Mask: Apply

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).
