Trying to use a picture as a mask


#1

So I have a video where I’m using clay to suspend a character and I want to crop it out using a mask. I have an image of the background that I want to use for the mask, but I can’t figure out how to do that.

Hum, if I understand correctly this is an easy setup !

how about that ? :
