Hello! I'm using picture-in-picture in PE11 to show a small video clip within my main video clip. What I'd like to know how to do is grudually expand this small clip to fill the whole screen as the video plays, then contract it again down to its original size. Is there a way to do this? Thanks for the help!
You'll need to create a keyframed animation for your Picture in Picture in the Motion properties of Scale and Position.
How you do that precisely depends on which version of the program you're using.
