I thought this was easy to figure out but after 2.5 hours, I can say that I have failed. I have placed my camera in my bedroom and shot myself couple of times. Now I want to merge those files. So in the final footage I will have 3-4 of me doing various things. I played with time effects and blending modes but couldn't manage to come up with solid look. Any help is greatly appereciated.
Note: if it is possible I don't want to delete certain parts of layers so that layer below is visible.
