    Just a quick question… A friend of mine showed me this video and asked me how they did it.. I had some ideas and thoughts regarding keying and stuff, but they did a very impressive job of “rebuilding” the background where the skateboards were keyed out. Anyone who has a few spare minutes or is just bored at work, take a look at:

    Any ideas on how this was accomplished so seamlessly? I’d love any insight. I’ve been using AE for a while now, and haven’t done too much with keying/compositing, so I’m kind of a noob in that regard.

    That’s a very impressive cloning job. I hope they use something like mokey to do the heavy lifting. Nice concept.

    Yes, looks like a massive paint/ roto job. Not impossible with some clean plates/ photos to fill in the gaps, just a lot of painstaking work.

    They used a motion control camera. One pass with operator control to follow the skaters. A 2nd pass with the movement data from the first pass gives them a clean pass to comp with. Easy as pie for post.

    I can imagine that painting the shadows back in underneath their feet was a bit of a PITA. Good stuff, though. Spike Jonze, workin’ it.

    I’ve got to get me one of those. Anyone rich or have a rich parent about to die that wants to front the cash?

    oh, yeah. of course. Tony Hawk paired up with febreeze and also eclipse gum, and they manufactured a board for the future… one where skaters can’t see it but still don’t know how to skate.

    From the Google video poster: “The skaters were filmed skating on green boards, then the boards were edited out.”

    Motion control cameras are pricey even to rent, is that really likely here?

    Spike Jonze was responsible for that video, so I’m assuming he had some cash to throw around.
