Re: trail effect...re-phrasing my question...

This brings up a question I have, too. There's also a commercial out there where some little kid runs through the house and leaves a "clone" of himself behind in different spots. I understand how to create this effect by grabbing a frame and rotoscoping if I just intend to use stills for the trail, but in this commercial, the "clones" are actually separate clips so that they appear to step out of the original actor. There's a recent sitcom title sequence that does this too (can't remember which). Maybe I'm dense or not understanding the obvious, but it seems almost impossible to me to get the two clips to match up at that one frame. I guess you could try to have an actor match up his initial pose with the exact frame you wanted him to "step out" of with the help of a monitor on set, and then mask and tweak as needed. If anyone knows how this is done, I'd be interested in hearing it.
