I have been using an external editor to cut between image sequences created with Blender, but decided to move to the VSE for efficiency.
With the externa editor (Kdenlive), when I made changes to an image sequences, it automatically updated it, or, failing that, there was an update command.
However, with the VSE, the only way I could find to update a strip was to delete it, add it again an recrop it.
Is there an easier way?
