Great, thanks! This info will be very helpful to get me familiar with AE. I have experience with green screen and keying in Final Cut so I was able to do this in AE, however, what I’m having trouble with is once I overlay the keyed person on the TV clip I’m using, I want to put the keyed person in the background and have the TV character walk in front of him. Is this done with the pen tool? Do you know of a good tutorial to show how this effect is done? Once again, your help is appreciated!
