So I have been using Roto Brush for years in After Effects. It was a tool that worked with a lot of user input, but it was so incredibly slow. And honestly with footage getting larger I think it had actually gotten slower, but Adobe has finally been working on an upgrade that is available in the current Beta.
Roto Brush 2 stills needs user input and it doesn’t do well with a lot of motion blur, but it is so much faster! It used to take sometimes minutes to calculate a single frame, and now in minutes it can calculate a whole clip.
I am not sure how much better of a roto that it does than the old version, but the speed in which it works means you can make changes and even work frame by frame, and work quickly enough to do a basic roto very quickly.
I am so glad for the public betas and them letting us use unreleased features.
