Greenscreen: Secondary Color Correction after using Color Key?
I have an actress green screened and I’m trying to get rid of the green that shows up in her hair when she does big movements. The easiest way I could think to do this is just use the 3-Way Color Corrector, isolate the green in her hair, and change that to brown.
The problem I’m running into is that when I put the Color Corrector under the Color Key and isolate the greens everything that’s keyed turns opaque black.
Is there a way I can add a secondary color corrector after a color key to clean up the spill?
Thanks!

What keyer are you using? Most good ones have a spill suppression capability that should handle the green you are seeing.

I’m using the Color Key filter that comes with FCP. I have options to change the Tolerance, Edge Thin, and Edge Feather but no spill suppression.

Try nesting the color correction.

Apply the Spill Suppressor filter from the Key submenu.
All the best,

Or make a Qt file of the keyed shot and then apply CC

Good suggestion but I need more control. The green is very subtle and the spill suppressor starts affecting other parts of the image before the green is completely gone.

Results are the same – the invisible keyed areas turn opaque black. Thanks for the suggestion though. Hadn’t though of trying that.

That would be the ideal situation. Unfortunately my work has a very quick turnaround and I’m usually making changes up until the last minute (not my choice) so round-tripping for anything gets very time consuming.
Agreed though, Motion/After Effects is definitely the way to go.

Turns out I should have been using FCP’s Chroma Keyer, it has much more control than the Color Key and for my purposes it’s getting the job done.
Thanks for the suggestions everyone.

Good Lord, I blazed right past that place where you said, “Color Key”. Check this out: https://www.kenstone.net/fcp_homepage/chroma_key_fcp_hd_monahan.html
