I have an image that I want to roto that doesn't have much contrast so the brush isn't recognizing what to remove or add. Is there a way I can manually do this instead of having an automatic/smart selector?? In the future I might want to just roto something completely random and the smart tool won't be able to "detect" it so I need a manual option too.
Freeze or hang
User interface or workspaces
The most efficient workflow depends entirely upon the clip. Sometimes all that is needed is some color correction, pre-composing, then running Rotobrush on the nested comp. I do that all the time. Sometimes the color correction is severe.
Other times Mocha AE is the best choice. Sometimes you need to stabilize the thing that is moving, like someone's arm, so that it doesn't move, then do the roto, then put the motion back in the clip. Sometimes a simple Procedural Matte created from color or luminance channels is all that is required to fix problem areas.
If you can share at least a sample of one of the most difficult frames we can make some meaningful suggestions.
If you want to explore Mocha AE the very best resource to get started is on the Boris FX website under Mocha Escentials Training. I would start there instead of just searching for tutorials. The professionals give you much better suggestions and explain things better than most of the tutorials you find on the web.
