I just acquired this program as I wanted to make an documentary video and I'm having a dreadful time with cropping videos on the actors speakers. I tried cropping before keying and that didn't work. What happens is the video seems to have a black mask around it and I can't control it the mask. It 's separate from the adjustment layer. So the clip becomes smaller and when published there's the same mask around it. An there anyone who can help me with the problem?
