I have footage of a guy watching tv with nothing in it. I now need to add the footage inside of it and need it to match the camera movements. I thought I saw a chapter about this in a book I have but can't find the book. Can anyone explain how to do it? I was doing it frame by frame in premiere but saw something that would do it easier in after effects. Something like matching the corners of the tv and locking the footage on top to those 4 points.
