rotoscoping issues

Is anyone here familiar with rotoscoping ?

My mate spent all day rotoscoping some footage on adobe after effects and it all looks brilliant in the preview. As soon as you render the clip it ends up clipping through and just being all over the place and we have no idea why or how to fix it.

Anyone have any ideas or advice ?
 
I'd have to see what the footage looked like in the end result, but is he sure he checked all of the stopwatches for each mask he made, so it didn't move around?
 
Yeah he used roto brush



He didnt use any stopwatches it was all done frame by frame with the roto brush



Thats how it has come out

That's pretty cool! It looks like the brush wasn't completely covering the person. That's weird, and you guys went through every frame in the after effects file and it's all masked out?

Yep if you view it as preview before rendering its perfect, no clipping or anything, as soon as it renders it just starts going like that
