I know how to crop an edge of a video clip, so that part of the image is missing.
What I want to do, is to MOVE that cropped edge over the length of the clip, without moving the other edges..
To do this, I'll have to set keyframes, but as soon as I apply a keyframe, the program tells me that in order to move a section, that section must in proportion to the film, and resets it back to a size that fits in the smaller area.
Which means the image is complete, but smaller.
How can I overcome this?
