Did you Freeze the roto?
Yes, i freeze it, and then when i go back to the composition and press play or jump to
a frame, the message pops up saying "Roto Brush propagating."
Thanks for the quick reply.
Same here. if i freeze it, then go back to change a few things let's say in the middle of the timeline, then AE would want to propagate from the very beginning to the point of interest.
If i'm done rotobrushing the whole video and would like to preview it, (without freezing it since it also takes as much time) it still wants to propagate. ???
