Rotobrush NOT WORKING

Question

Im having extreme issues with the rotobrush tool. The tool always works good in the beggining, but about 1/4 through the footage it begins to lag. Then half way through the footage it crashes or freezes. The footage is normally 3-5 clips. I have tried to get help on the chat, trouble shooted, tried different versions of premiere pro and after effects. Eventually i restored my laptop to factory settings to see if that was the issue, but it wasnt. Ive tried rotobrush 1 and 2, and have been getting the same result. Can anyone help? The online chats arent helping at all. i use after effects via dynamic link.

It's simply buggy as hell and piping it through DL doesn't help, because this somehow is currently busted as well due to issues with caches and hardware acceleration, even more so on Macs, unfortunately. You should realyl explore exporting the relevant bits as image sequences and natively import them into AE. That may at least avoid some of the agony. Other than that of course this could be a classic case of using a toothbrush to paint the fence, i.e. using the wrong tool. Rotobrush has no magic powers and a lot of people simply use it all the time because they don't know better and haven't explored other methods. Therefore providing some reference frames/ screenshots may also help to steer you. Perhaps what you are trying to do simply requires a different approach and could be as trivial as some channel effects to generate mattes plus some simple masking. Who's to know?
