How did they do this?
Hey, i saw this a couple off years a go, before i was into visual effects and motion graphics.

I understand how to do this with a steady shot. But how could they achieve this with dolly shots and pano’s, moving camera…?
Frame by frame? Tracking masks(uh possible?)Just curious.

How exactly did they get a complete BG plate on a moving shot that has a hole where the board is roto’ed out?
Thanks,

Exactly, that what i am wandering about.
How can you rotoscope this if the background is moving?Steady shots are easy.

for each frame of rotoscope.. they possible could clone stamp an area simliar.. to fill in the hole.. like dave said.. painful but rewarding if done right
“kis” it

There was a post in the YouTube comments that they used some sort of specially outfitted camera that gave them zoom/axis rotation data that could theoretically be very useful in rotoscoping out boards. I don’t know how this person had access to information about their workflow, but it could be a piece of the puzzle.

I’m having trouble opening this link from where I am at the moment, but it sounds like it’s Spike’s music video that was shot with motion control rigs. The cameras would make two passes, once with skaters doing their tricks on green boards, a second pass exactly the same with no-one in the shot. Then it was just a basic key and clone of the two shots.
People have imitated this with rotoscoping but usually the shots aren’t as elaborate or have complex camera moves like Spike’s clip because, well, not everyone can afford to set up motion control rigs.

Actually, they may have just used Mokey. I downloaded the evaluation version a few years ago and the tutorial included showed the software removing a skateboard. Very impressive stuff, (at the time it wasn’t right for what I was looking for and too expensive to just get) but it’s very cool software.
