I'm having issues with this. The roto brush will only propagate half of the clip and then it just stops.
I realized the end of the clip needs some touching up but I can't even get to that part because it stops propagating around the halfway mark and all I see is a black screen. I try to go frame by frame but it doesn't even load anything besides the black screen after the halfway point.
How am I supposed to edit the mask if it won't even let me get to that point in the clip? It's only a 14 second clip as well, so it's really frustrating. I've tried for hours to see if it will continue propagating so I can access that part of the mask to no avail.
The green bar showing the propagation just stops after a while and all I get later in the clip is that black screen so nothing is letting me edit the mask.
I have a decent computer but this is definitely eating up all my RAM, but what's the point of it doesn't even allow me to correct the mask?
If there are any fixes or there is anything I'm doing incorrectly, please let me know.
Thank you for reporting this issue. I'm sorry to see you're experiencing this problem with Roto Brush. Would you mind posting your system specs, as well as the resolution of the clip you're using with Roto Brush? Do all clips exhibit this problem, or only a specific one?
A screen recording would be helpful in diagnosing the problem. It would be even better you could share the project and footage with us by collecting the project file/footage and sending a link to firstname.lastname@example.org. This would allow us to see the problem firsthand.
Thank you again for reporting this issue and for using the After Effects (Beta),

Thanks for the reply.
My system specs are as follows:
Intel(R) Core(TM) i5-9400F CPU @2.90 GHz 2.90 GHz
32.0 GB of RAM
64-bit Operating System, x64-based processor
I'm about to get a screen recording to share to the provided email address along with the project and footage.
I will attempt roto brushing a lower-resolution version of the clip and see if that helps. I'll try the other fixes as well.
I did see a green screen in the footage as well but I thought it was due to the roto-brushing. I will checck again.
In the latest version (v22.5), Roto Brush doesn't work at all. I have confirmed with several other studios that they have switched to other tools already. The behavior is consistent across both Mac and PC. Roto Brush will track for about 30-40 frames and then lose all of its tracking and start over from the current position. It basically creates rotoscopes in "chunks" and loses them along the way, never piecing together a single, fluid rotoscope for the entire clip. And this happens on low resolution footage as well (2k and below). In general, very disappointing.
