Super Tight Junk Mattes problem
Trying to use Aharon’s technique for super tight junk mattes, and there’s a problem.
My comp is 130 frames. When I do the auto-trace, it appears to work (ie. the info panel counts up from frame 0 to frame 130) just fine. But then when it creates the new layer, the solid only lasts the first 34 frames, and the mask doesn’t move–it’s just stuck at the outline for frame 0.
Any suggestions? Thanks!

It’s set to trace the full work area. And like I said, it goes through the full frame count in the info panel (Tracing frame 0, frame 1, frame 2, etc.) all the way up to the end of the comp.
But the new traced layer covers only a portion of the work area, and doesn’t change from frame to frame.

Sometimes the masks are so heavy that it will bog down AE making it only look as if there is a problem. I suggest you track matte a solid through the alpha of the auto traced layer. this will confirm your problem or reveal a solution.
