Green Screen fixes

I have a client project where someone shot on green screen, not awful job but a major spill issue with them standing on green screen and not controlling the light bounce. So they have the reflection of green on their chins and under their hands and arms when they move due to the lights angled down then bouncing off the floor.

I have it pretty cleaned up and screened outside of that (mildly impressed with myself since I haven't done green screen in years), but I can't for the life of me get rid of the green reflections on their arms. It's not their arms disappearing into the screen, but just a blatant green tint to the lower side of their arms and hands specifically.

My thought was to use 3-way color corrector and try to isolate the color and de-saturate and tune it to be more natural but I can't isolate it consistently.

I also can use After Effects also, I just stuck with FCP out of initial convenience, considering re-starting in AE... tips and tricks appreciated! The client is satisfied with it for the most part, they understand the difficulty I ran into with the way it was shot. They hired reality show camera-op so they also refused to keep steady shots (zoom, whip-pans, etc) so I had a ***** of a time with motion tracking manually on the green screen. I can't help but feel like I am not doing them justice by just blaming the shooters and director.

This is why I prefer being hired for production and post for these small projects, just doing post is more work!

Don't the chroma keyers in both AE and Motion have spill suppression settings? Have you tried using those?
 
Phyx Keyer, best money I ever spent.
Yes, you want to use Spill Suppression, not a Color Corrector. Spill Suppression knows what you're looking for and doesn't effect the whole image like a CC filter will.
Phyx Keyer, seriously, check it out. It's spill suppression is the best, as well as all the other tools it comes with.
 
This is what I get for not regularly using green screen. Thanks guys, will try that out. I was using some of the FCP filter spill suppression in it but wasn't getting the effect I wanted, will try out a third-party one.
 
What are you keying it over? I had the very similar thing happen a few years ago -- some clowns had shot a totally bald guy with very poor lighting and lots of spill, I ended up with the repair job. I tried every trick I knew, and the results had him either looking radioactive or pin-headed. I finally talked the client into a re-work of the design, and keyed the guy over a V-Set that had a lot of green in it. With a little positioning, the green noggin looked like it was picking up natural reflections....
 
Not a whole lot of options for changing what it's being keyed over, the whole reason they did green screen was it was a promo spot that was shot for a venue, so the have to be placed at the location.

The actor had done the whole main piece on-location which they did with a serious budget, but this online promo piece was an after thought, once he was back in NY. Which is why they aren't too angry about the quality, but I just know I can make it better.
 
If you have AE, you'll get a much better result with it (Keylight) than anything you can get with FCP.
 
Phyx Keyer in Motion, nothing can touch it. Nothing can touch it, and I stand by that firmly. Considering it was formerly a Shake plugin. Think about it. Period.
 
If it were my problem, I'd try keylight first (since you have it already) and spend $200 more if that didn't work.
