I have a mask set for a video clip, and I would like to crop this clip using the (bounding box of the) mask as the new clip boundaries. Basically, I want to extract some moving part from a video.
NB: The mask is animated.
It is a clip mask, not a Node’s Box Mask, though even with the latter I did not find how to achieve this (crop node does not take crop size as a linkable parameter). I may consider to write some Python if it is the only way, with a bit of help about which APIs to look at.
