Key To A Good Green Screen Keying?
I have tried pulling many different keys from my green screen which is green paper non-reflective. I have changed lighting many times and i have stood from 2ft to 8 ft away from the screen and my keys are still rough and sloppy, does anyone have any advice. That would be great. Thanks

With what are you shooting? Sounds like your camera uses some pretty severe compression or has a lowlight setting enabled somewhere so it produces noise.

The green screen should be evenly lit across the whole thing, and as close to one single shade as possible.

… and that single shade, as recorded by the camera, should be as close to R0 G255 B0 as possible (or the blue equivalent if you’re lighting a bluescreen).
Once you start allowing less-saturated greens onto the wall, you open the door for grays and browns that match the grays and browns in your subject. If you also allow a bit of greenish spill from the wall to your subject, you’ve got trouble.
So it shouldn’t be sort of green or almost green, it has to be green. Nice, saturated, green. Not too light, not too dark, no olives, no browns, no grays. Green.
And move your subject away from the wall so no green reflects (spills) back to the subject.
