Green Screen Lighting (ex. photo included)

[ChromazoneX]

Hello! I have 4K footage of 4 hosts in front of a green screen, but unfortunately one of the 3 hosts casts a shadow which creates severely dark green screen footage. I can use ultra key and remove other parts of the screen, but the shadowy part is problematic. When I fix the dark part of the screen, I get white speckles throughout the video. When I fix the white speckling problem, the dark shadow is horrible again. I can't find a balance where I can fix the dark green screen shadow as well as the speckling. I'm using Premiere Pro CC 2020.

One thing you can try when your background color to be keyed varies is to dupe and stack your footage, and key the different areas separately.  Create a mask on Opacity of the higher video layer.

Thank you, I'm trying that now!

Below I posted more photos of what the screen looks like too

They are way too close to the green screen.  They shouldn't be casting a shadow on it.  The shadow area isn't green any more.  It looks mostly black and in the same color range as the guy's shirt.  That close, you also risk picking up green reflections on the talent that will key out.  You may need to rotoscope to fix this.

In After Effects when I've used Keylight it takes about 12 hours to render the first half of this video (6mins approx.), with Rotoscoping will the rendering time be about the same time? I'm not as familiar with After Effects as Premiere

First, you need the screen stretched flat to get a smoother tighter hue/tonal range out of it.

Second if at all possible, more distance between subjects and screen.

Third, use a light meter to set and adjust light on screen for most corner to corner evenness.

We're hoping to use a painted wall soon so the consistency will be solid. Once we use a wall instead we can increase distance too. The light meter is a great idea too. For this, I'm unable to reshoot, but I am able to get their surroundings nice looking, but that middle area is really blotchy especially when his arm moves.
