Evan Abrams demonstrates some simple cloning techniques in After Effects where he shows how to duplicate people in a video clip. Check out more tutorials for After Effects and such at Even Abrams’ site.
Evan Abrams writes on his tutorial: “Have you ever thought: “if only there were two of me?” well now there can be… in videos anyway. This is the most simple of all cloning techniques using non-interacting parts of a frame and blending a locked off shot. This has added interest when in the second half the two clones actually throw a ball to each other. It’s not as crazy as it sounds if you have a gene-therapy lab and some stem cells. Then you can just make your own clone and never have to worry about these after effects things again unless the clone decides it wants a life of its own and kills you to take your place. Just something to think about.”
