Greenscreen recommendations I'm suffering with Greenscreen already several months. So I would appreciate any recommendations.
As you can see on the right side there is a spill on the head and arm.
My setup:

2 daylight bulbs (45 W CFL-Daylight) with umbrellas for subject 45 degree left and right.
I also tried with and without 2 softboxes (45w CLF-Daylight) to light greenscreen. From what I see the greenscreen is not perfectly lit.
Greenscreen is 2 meters behind the subject
I key it in Final cut pro
My camera is Sony 5100 f1.4, iso 100, 25 fps, shutter 1/50, 1080p

The main problem is that I don't know what I need to adjust. Is it the greenscreen than should be lit better or something else? Do I need more light or should it be dimmable?

Also I tried adding 2 softboxes on the bottom. It helped with colors on the bottom of the screen but not with spill.

I'm open for any suggestions. Thanks for your time.
Nice explanation of your problem.
I would simply move the two softboxes higher.

To minimize the falloff put the lights about the center of the framing of the camera. If your camera is targeting the green fabric at 1mt (I see the camera is pointing down a bit) put the lights at 1m.
Probably the softboxes have less power than the umbrellas. Try to add a stronger light on them. Just watch they do not overheat. Safety first.

I do not know if this would help, but If you do not use the window I would put the green screen there because it seems the room is longer in that direction, which will help you have a less green spill on you, and use a longer focal length.
