Question

Roto Brush selection dissappears ever 10 frames or so...

I didn't know when i made a selection with the Roto brush that is would only keep the selection for about 10 frames...

I naturally am tracking frame by frame given After Effects limitations, and still after only 6 to 10 frames the section will disappear completely... leaving me to redraw the selection, which After Effects never understands, naturally, leaving me to use the red brush to make the exact same selection I made with the green brush... so I try to only use the red brush the first time.... it doesn't work like that. So ever 10 frames I have to stop, redraw the selection, then re-redraw the selection.

So... why?

    Well, a few minutes later ... about 15 seconds into rotoing a shot frame by frame, I accidentally turned the part of the screen that isn't selected black. No matter what I tried in the options I couldn't undo this and get the original view (which you NEED to be able to ROTO, something Adobe might need to learn).

    Anyone know of a program similar to AE that WORKS????????

      The Roto Brush tool isn't as intuitive as it looks. It is highly recommended to go through some training resources first. You could do this: Learn Advanced AE Rotobrush in 20 Min - YouTube 
      Even this would help: Roto Brush in After Effects CS5 and later | Creative Cloud blog by Adobe

      As far as "similar to AE", no. It's the only program out there like it. It is the best at what it does which is both motion graphics and compositing. HOWEVER, if you're just doing compositing, there are a few other pieces of software out there that you might prefer. Nuke (expensive) and Fusion (much better price) are both apps that are focused on compositing. They are node-based, not layer-based, so it might take some getting-used-to. That said, if you're at least somewhat familiar with AE, it might be better to watch that 20-minute video I linked above instead of spending weeks learning how to use new software.

      Insulting that you would direct me to a 20 minute video instead of answering why this program isn't working correctly...

      do you just not know why every 20 or so frames the selection disappears? Then don't post on a forum asking that question, very simple paradigm the ACPs just cannot wrap their heads around. I'll buy Nuke and Fusion, I don't care how much they cost I need something that works!
