paint and masks get corrupted when I go to export
Hey guys,
I did some effects on this clip using the paint tool and the rotobrush. Basically I used the rotobrush to isolate a video of a girl walking and then used the paint tool to color the background behind her, giving it a cartoony effect. I've spent a lot of time animating this but when I went to export the paint is flashing in and out and the mask I put on the girl also cuts in and out. It runs completely fine in my timeline and all of my masks are correct, so I'm not sure why it messes up when I try and export. Does anyone have any ideas. I'm more than happy to share the after effects file with you so you can see what i'm talking about or try to trouble shoot it yourself.
Thanks
