Creating a vector outline of an object in a video with a green screen?

[Chris Smith]

I didn’t look at the example, but you can key the footage so the alpha is in the shape of the subject. Then use the AE ‘auto trace’ function to get a vector outline. It usually needs a little bit of clean-up though.

I’m confused: the question in your subject line is irrelevant to the body of your message. The cheetah and skateboarder were NOT shot in front of a green screen (and, for that matter, they’re not vector outlined) – that’s the whole point. They were “cut out” by good old grueling, labor intensive roto. The artist is demonstrating his abilities in this department, and he certainly has them.

sorry for the mix-up there. the title line is supposed to say “without” a green screen, rather than “with”
thanks for the feed back guys!
