RotoBrushed Matte Dissapears
Hey All,
Trying to teach myself some after effects for a simple plate compositing task and I’m running into what
looks like a basic no brainer kind of problem but I cannot crack it.I have my footage. I had it highlighted in the timeline and it was in my layer window. I created the mask. But then when I scrub through the clip to check the rotobrush mask at second 1 frame 12 it dissapears. I don’t have any keyframes and there are other color correction filters that are still there. I have tried re-doing it ten times and without fail the mask goes away at some point. I’m missing some really obvious piece of this puzzle, what am I doing wrong????

Dave is correct.
Specifically, regarding your Roto Brush issue, you have moved to a time that is outside of the Roto Brush span. Read the Roto Brush documentation for details about that.

So this documentation talks about moving through the clip manually but would I be doing that in the layers panel or the timeline?

The Rotobrush Tool is active for use only in the Layer Panel. Of course the results of the Rotobrush Tool affect the Comp Panel content.
