I animated a mask for a 15 second shot. After completing the animation of the mask, I went back and scrubbed through the shot to make sure everything was ok. But, I came across a portion of the shot where the same mask points had the right side of their mask handles suddenly appear to have stretched out further than they were animated, as well as their position changing.
I've attached a screenshot with the points that had the problems. I went frame by frame through that same section, and there was no time when the handles of those points would've required the handles to be in the position they are now in.
While I worked on the mask, I made a point of scrubbing back and forth to make sure the mask was animating as I needed. Thoughts?
