I have a problem.....
I'm doing a bit of Chroma keying against a blue background, no problem, works fine.
I want to superimpose this to the right of the screen but....... There's a bit of the shot I want to crop from the left hand edge of the chroma shot where the camera was out. However I try when I crop the frame to cut out the bad left hand edge I can't get the superimposition to go on the right hand side of the shot. The bad bit I try to cut out reappears.
Sorry if I sound vague, I don't quite know how else to describe it.
Anyone help ?
