Its something to do with memory caching / updating frame. When I purge Image Cach Memory it updates the frame correctly. But you'd have to do it everytime you moved the mask. I still can't figure it out.
Sorry 谭小永 you can't speak English. I can't speak Chinese.
When animating a mask path I usually set keys every 5 frames or so then go back and adjust the inbetween frames as needed. In AFX 2015 the mask won't actually update what its masking out between keys. Making adjusting the mask impossible!
Its hard to explain so here's some pics.
I tried animating a path and did not experience any anomalies. Can you try the same thing in a new project?
Thanks for the reply Kevin.
Its definately an issue. I'm trying to isolate the problem and so far I think its;
1. Related to nested comps not updating the cahed visual memory through the comp tree ( because I don't get the issue on a base layer only in nested comps).
2. The AppleProRes 422 4K codec I shot using a Blackmagic camera. As the issue doesn't seem to appear with HD.
When I get another moment I'll provide a more detailed analysis.

Did you solve it Dan?

Do you have Any frischluft Plugins Installed?
