I don't know how to ask this but this may be a dumb question.
I have been working with green screen effetcs with AE. My qestion is
how do I keep the green screen footage (charachter) in the same spot
as the background if the background camera video moves a bit ?
So example some one records a car driving down the street with a video pan. If I decided to put a fan watching the car go by, how do I keep the fan in the same spot on the background before and after the camera move. I tried motion tracking a spot on the background but that didn't work well.
