hey guys, so lately ive been working on a school project. im planing on presenting it through a video. however, i need some assistance as to how to achieve this trick: http://www.youtube.com/watch?v=N-mIM4-3v1g hopefully a lot of you guys have seen nat's vids and has seen scenes in her videos in which there are 2 nats. I was wondering how would I go about doing that? I mean, i understand that I would have to film 2 separate parts, but the part i don't get is the how to combine them into one scene. what software should i do this with? imovie? thank you so much in advance, guys.
