green screening multiple greens?
on Aug 20, 2014 at 6:53:53 pm

Hey guys! I have an .exr sequence that has a few different types of greens. I can't think of a time where I have had to deal with this so I'm looking for some tips on what a good procedure might be to get the scarf out of the image? Should I be rotoscoping it? Thank you for your time

A method I like is to use the Selective Color effect to get a more even green to key. Check out this tutorial, it covers the technique: https://www.youtube.com/watch?v=woZflhiwJ6Y#t=49

For your video, you'll probably need multiple keys though.

Primatte should be able to solve all your greens for you in one key.

If not you could duplicate the layer and key only the scarf part. then use that layer as a trackmatte for the original layer.
