So what i want to do is make 2 videos OF THE EXACT SAME BACKGROUND of me being on 2 different parts on the screen and actually talking to myself.. if that's correct. Is that possible? Like just cutting the video in half. and then putting them back together. I'm trying to do something fun for school. Do i need to do some weird super-hard stuff with chroma keys and stuff or is it simple as i said it before?
If you are planning to shoot in controlled conditions - in a studio or inside your room, where light never changes and there are no people/cars moving behind you, and the camera is locked down it does not move)then it's quite easy. All you need is to shoot the two instances of the actor/you one after the other so that the camera will not move. A simple mask on the top layer should do the trick.
If you want to shoot outside, with elements moving behind and light that can change... it's a bit more complicated, but doable. Plan ahead and choose your location so that at least one of you stands in front of a large object (wall, column, van with no windows) that can be easily isolated with a mask.
AE is both deep and broad, and it's very hard to jump right in without taking a little time to learn fundamental concepts first.
