Mask that follows an edge
Hi, I’m trying to mask out the lenses of a man’s sunglasses. I have duplicated the footage layer twice (once for each lens) and darkened the masks so you can’t see the cameraman who is refelcted in the original lenses.
The problem: the man moves his head around a lot so I have to keyframe the masks every one or two frames. The glasses frames are much lighter than the lenses so there is a distinct border there. Is there a way to glue the keyframes to this border so that they follow the movement automatically?
Thank you for any advice.
