Nick,
WHy go through the hassle of running it through PS? Just blur the footage. Precomp the layer then do the auto trace.
Steve,
Yeah, Pathfinder type actions is what I was thinking would be great in AE. Especially to deal with the auto-trace creating so many masks. Or an auto trace option to combine the masks ala Pathfinder.
