Green Screen issue - Advice needed - vid Death Stranding

[Slyelessar]

Hi guys, I have recently acquired a green screen for use with the channel. I have been getting some fuzzy areas that are very difficult to clear up in premiere. I thought I had the lighting down, but is this specifically because of it? The video below of an unwrapping and review of the art of Death Stranding has some scenes where the background is fuzzy. Any help appreciated.

this is an educated guess , but green screen requires a virtual shadow less background. so my guess is the lighting you are using

Do you think a third light shining from above and behind would be helpful?

I am also wondering if it is the way I am doing the Ultra Key in premiere Pro.

im just learning about green screen, but it cant be much different to using a backdrop for photography, were i dont want a shadow cast to spoil the shot.
if you have a trird light its worth a shot
