I've been wondering if and how to create the cloning effect within a moving frame and without a green screen. In other words, is it possible to to convincingly edit together footage the subject taken while the camera is moving in, out, and around him/her, and then that integrate footage into a later clip taken of the subject intersecting the same spaces as the original? I've seen clips where the subject cloned himself/herself several times through the process of animating masks. Of course, these clips a done with a stationary camera across all of the takes (which makes great sense). I was just wondering if the same could be done but with a moving camera and no green screen.
