Green Screen Review

Hey everyone, considering our current project of chroma keying ourselves into a movie, here is a good review that I watched and refreshed some things I forgot.

Take note at a couple of parameters in After Effects that you may forget when chroma keying in Keylight...

Screen Pre Blur- use this after adjusting your screen matte, in the video he uses a setting of 2 and it helps to "feather" the edges through blurring.

Screen Shrink/Grow- use this to get remove the soft green edge around your subject, the video uses a setting of -3.5, (*negative* because you need to take the green out) but this is determined on a case-by-case basis.

And most importantly to get a good chroma keying result- use the eye dropper as close to your subject as possible!

Best of luck with your keying.
