when working in after effects i have been selecting the roto brush. I get my first frame on my first layer set the way I want. then when i go to the next frame, the roto brush will not work. I can select forground or background with red or green circle but when I release it does nothing. this same failure has happened randomly in the middle of a project. the only solution I have found so far is to dump that composition and project and start all over.
has anyone else had this problem, or know how to fix it.
I forgot to mention that i gave remote access to Adobe twice for a total of 3 hours and they cannot solve the problem.......thanks adobe
