I’m an idiot. Moving and resizing is still available after you’ve masked off an area in the pan/crop window. All I had to do was click on the position timeline as I was on the mask timeline.
Yes, it does answer the question. I’ve been playing around with the track motion, trying to get used to that. I guess I’m just curious as to why I’m unable to crop and move video after it has been masked using the pan/crop window.
