WARNING:
Based on the most up-to-date fork of VSE_Transform_Tools, we're gonna solely focus on the crop tool here, since Blender 3.x now comes bundled with Video Strip transformations provided by the original add-on like Grab, Scale, Rotate - and other goodies that were out of this scope.
- Go to the latest release & download the
blender-vsc.zip
file - Insider Blender, go to
Preferences > Add-ons (sidebar) > Install
, importing the zip file you just downloaded, making it appear listed in theAdd-ons
section. Enable it by clicking in it's checkbox
That's it! You should see a "blade" icon now in the Preview whenever you start a Blender project in Video Editing mode
