PRIMATE, ADMIX, LIGHT WRAP, to quickly clear the green screen

IBK COLOR, IBK GIZMO

ChromaKeyer

KEYLIGHT

PRIMATE&UNPRIMATE

Some of these methods are two-dimensional identification of colors for keying, while Primatte is color keying in a three-dimensional perspective. The first two I think are suitable for simple keying, while Primatte I think will work better.

After that, the teacher also talked about how to use channels to change the background color.

For the assignment, I used the channel to give the main characters a clear alpha layer, after which I used keylight to subtract the green screen. After toning, I combined the background with the characters, and removed the mics with masks, and used tracking to move the background with the characters.
