I've read the rest of the posts above. It's only an 8x9 area. Anyone know what a quart of BM Neon Green will cost me? Helm paint carries it in my area and they are closed today. Course I could call em tomorrow, but I'm curious. The Aura gallon size is 64 bucks. I could not afford that unless I robbed a bank

Primer. Would I have to re-primer this wall? I hope not, now that I have primer and a coat of paint on it - If I have to buy more paint to fix this, I'm hoping a quart will cover well enough to give me two coats and cover well while not letting the old color bleed through.

I'm a little puzzled...you're using this for video production and testing it with a sophisticated software, yet you can't afford a gallon of decent paint? Get quart of decent paint and be done with it.

And as far as green screen effects go, so long at the color field is consistent you should be fine. That means flat and even. You should be able to key in to the specific color you want to drop out from your video frame by simply sampling the color in software. The reason electric green is used is the simple fact that it is a color you rarely see in the real world...you can drop it all out from a video frame and not drop out part of your foreground subject matter. At least that's how it works in software that I have used.
