Color difference key: lots of spill on talent’s legs
If you go to this site:

You can DL some great great screen practice sequences in HD, free.
So, I’m struggling w/the first, the talent in the green screen stage w/the camera dollying to the right. There’s a lot of green spill on the talent’s legs, and while I can pull a nice key on her, her legs wind up semi-transparent.
I’ve addressed this by doing the best key I can w/CDK, and then duplicating the layer multiple times to build up the opacity. AFAICT, this works fine. However, it feels bush-league.
IS duplication of a keyed layer a valid workflow?
Thanks.

[Eric Chard] “IS duplication of a keyed layer a valid workflow?”
Yes, but usually you’d do a separate key with different parameters on the duplicated layer to try and preserve the legs (or whatever part you happen to be working on) and then use a junk matte/mask to eliminate any issues that causes.
Most difficult keying takes some back and forth between keying and using junk mattes/masks on several layers.
