How to Rotoscope dark images on dark background?
on Aug 18, 2014 at 6:06:03 pm

I am trying to do a composition where I'm adding a new background to some footage.

The actor has a dark shirt, it's filmed in low light, and the background is completely black.

Instead of tirelessly hand drawing rotoscoping every frame, is there a way to somehow boost the gamma or exposure or levels in someway to be able to have AE find edges better?

Rotobrush could very well be your friend in such a situation, but don't expect to be an expert from the get-go. It isn't intuitive AT ALL, you need to read up on it and run tutorials. It certainly doesn't lend itself to tips in a forum post.

If you look in AE Help, you should find a very valuable section on Rotobrush Resources. Very valuable.

Maybe. We would have to see a still from it or something to know better.
I mean, you can apply Curves or Levels and precomp it and try using RotoBrush on the precomp.

If automated solutions don't work, this page [link] has some good tips on rotoscoping to make it easier.
