Video noise and harsh shadows on green screen caused by feet We have a recurring shoot where we continue to run into the same two issues. Our set consists of a medical exam table sitting on top of a green screen. The talent sits on the exam table and we record 'Doctor/Patient interviews'. 

ISSUE 1: When the talent is on the taller side, their feet hang down past the bottom of the exam table and create really harsh shadows on the green screen, making the footage very difficult to key.

ISSUE 2: The dark area on the front of the exam table, behind the talent's legs, is very noisy. 

I believe these two issues are linked and both have to do with lighting. However, I have yet to find a permanent solution to either one of them. I am currently setting a small LED light in front of the camera that helps with the shadows, but it still isn't solving the problem. 

Our camera is a Panasonic HMC150 and I use the 'Keylight' effect in After Effects to key the footage. Keying is very difficult around the feet shadows and some of the green reflection shows on the exam table, which in turn, ends up being keyed slightly creating a lot of noise. I use the 'Remove Grain' effect to help remove the noise.  

Any advice on a different lighting setup, keying solution, or anything else that could help this situation is greatly appreciated. I've attached images demonstrating the issues.
To reduce or eliminate the greenish reflection on the front of the table, you can buy some dark gray or black construction paper, or something equally non-reflective, cut it to size, and tape it over the 2 dark rectangles on the front of the table.

I have 3 different solutions for the foot-shadows on the floor.


You could point a semi-dim spotlight directly on that section of the green screen. Make sure to mask it so it doesn't hit the dark rectangles on the front of the table too much.
If the camera is always stationary, you could lower the camera slightly so the talent's feet never extend past the dark rectangle on the front of the table and into the green (as the tip of her left shoe does in the pictures you included). Then you can mask out that part of the shot instead of relying on the Keylight effect.
You could just move the camera about a foot closer to the talent so you crop out the bottom of the table (and the green in front of it). You can also do this by cropping the shot during post production.


(Or, obviously, just get shorter talent.)
