Hi, I am separating some people from the background and I find that many times using the roto brush and refine edge tool I get a lot of noise and just some flat out weirdness. Chatter reduction seems to do nothing to stop it. It's frustrating - sometimes it works beautifully and sometimes it just doesn't.
I have put a video up to show an example. You will notice the man's face has insane chatter and noise the whole time. The woman looks fine and then her hair starts...pulsating light or something at the end.
I just have no idea if this is something I can control. I know there are a lot of individual settings within roto brush and refine edge but none of them seem to address this problem. Especially the hair.
