I am having a problem that seems to be unusual in that I cannot seem to find it on any AE rlated forum, or in any tutorial, or any set of instructions. I've used Rotobrush before, not extensively, but with success after a lot of patience. I'm not skilled, but learning. I usually use AE for stabilization, removing bugs from timelapses, and color work. Very very slow/new with more advanced stuff. I can animate/mask in Vegas Pro a lot easier than AE, if that is any indication, but I'll get better as I learn.
In using Rotobrush to clear the area behind a flapping flag, which usually covers the entire frame, but in the instances it does not, I'd like to see the image behind it (another layer)
In this comp, I've got another layer isolated with Rotobrush and Paint - successfully frozen. Of course, this layer has Rotoscoping on every frame.
In the flag layer, it is my suspicion that I need to go back and let is create contiguous segments even though there are seconds during which I need no Rotoscoping. However, doing this just adds to the time it takes for me to do anything. I'd like to work forward, but be able to go back and touch up if necessary.
Why is it not possible to freeze only selected segments or sections rather than the whole Rotobrush instance? (that's one question I keep asking as I open/close different comps) I'm not done with this one, but if I close it so I can work on a different clip, I have to wait a while longer than I have patience for since it does not propagate if I go to some other window/program ...in other words, it hijacks my computer.
OK< so anyway, here's the issue: I've got a section of the flag successfully masked with Rotobrush. Then the flag fills the entire frame again, and a couple seconds later an area of sky appears behind it so I start to roto again. Immediately it creates a 10 frame forward and 10 frame backward span. I don't want it to go backward at all, in this instance. Do I have to count frames?
So I deal with that, and am Rotobrushing forward, and I get to frame 11 past where I started, and I recreate a new base frame, and go all the way to the end of where the flag reveals sky, and now is filling the frame again, so I go back and start to Refine Edge. All is well until I get to the frame just past frame 11, whether I created a new base frame or not, in this area (not always the same - it is not the clip!) suddenly the entire layer preview turns gray, or pink, depending on the mood of AE, or whaever it is that I am doing wrong. I can't get the pink frame to show up again, but I can undo the refine edge, and now I see the mask in the area (upper corner near the edge of the flag) has a bunch of pink lines in it, like there are multiple rotobrush instances piled up and confusing things.
So I'd like to not redo this entire section (yet again) after deleting all the spans in the area, especially as patiently doing this multiple times has no good effect.
What am I doing wrong? Again, I can find no reference to this anywhere.
EDIT: The gray goes away if I delete the Refine Edge after the second base frame. But it comes right back after I try to get the next two frames worth of refine edge...each frame, regardless of order, causes the gray. Still haven't seen the whole frame pink again.
