Years ago in the remaking of the Star Wars movies, the alien figures that was played by masked humans, were superimposed by CAD figures, with alien skin and whatnot. As much as I know, it was done by giving an input to the beginning frame of a sequence, and the software would remake the whole sequence.
I ask if anyone knows with which software and how to replace the whole figure in video. I know there is software for remaking whole sequences, I just don't know which is good enough.
Another thing would be to change the skin texture in, say, inch deep, then I could already change the actor into an alien. Naturally, also for whole sequences.
--- If there are any video-savvy persons out there, please, let me know.
NOTE I've tried several video forums, but got stupid replies like do each frame with photoshop. With a 30-min video it's almost 50,000 images. It seems some people don't realize the difference between still image and video editing.
