Hello. I've been having this issue many times when trying to freeze and propagate a finished roto brushed layer in a composition.

It takes up to 8h to finish and it constantly gets stuck and lags on every percent and it annoys me.

It wastes me so much time and i don't know how to fix it. Also the preview window completely went gray when propagating the layer and i can't see it. Propagating is very slow and it takes about 20-30 minutes to propagate a single frame and that can take ages to finish it all so if anyone knows a solution for this and how to possibly make it faster, please let me know!

Thanks in advance!

Thank you! I'm gonna try it. Does the18.1 version of After Effects have the Rotobrush 2.0 and can i import the project file from the version i'm cureently using? I'm using the 2021 version and i wonder if that will work.
