Building a greenscreen

I've done green screen projects before using giftwrap. Instead of spending 50 bucks on that we spent 30 on some hardboard and paint. Gotta make the floor out of some paper and paint it for a scene tomorrow, should be pretty seamless.

I picked the paint by sight and I think it'll work out pretty well. It's a behr standard color, I'll get the name tomorrow.

The old trick is to go to a linoleum store and ask for a deal on a flooring that they can't sell 'cause it's too ugly. Tack it to the wall and floor, with the ugly ass surface down and nice smooth bottom surface up. Tack it with the proper curve, paint it, and shoot!

Whatever.
 
Ended up nailing it to my wall today. We're filming for an episode of our school's news network so we didn't have time to really fine tune it 100%, but it works great.

One board overlapped so we just put some masking tape seams and painted over them.

Can anyone recommend a program to key out colors? Right now I use premiere pro's chroma key but I've heard there are better choices.

Couple pictures & the paint label:

isn't the subject too close to the green screen? The light might bounce and "paint" the subject from behind, and it's a nightmare to deal with in post-prod.

Just my two cents

In this picture, the subject is too close to the background. You can see green spill all over his shoulder & sleeve on his left/our right. As previously mentioned, even with the best keying tools, that will be an issue unless you create a mask around him or something (more of a PITA than it's worth). Ideally, you need 5+ feet between backdrop & subject in confined spaces like this.

Like tcindie said....Keylight rocks. I've had nothing but good results with it.

EDIT: Sheeep - the color you came up with in the Behr paint looks great. I'd love to see it in pics that were properly white balanced, but it looks like it does the trick w/out having to buy $80/gallon paint.

I understand what you're saying about the light shed being green. My lights are spread between school and another friends house so I was just using 2 worklights. We tested it prior to shooting and it worked well enough.

I'll pull out some screen grabs for ya. Theres 2-4 coats on each board, unprimed, so it went on really well too.
 
Heres a video clip from the project:

You can definitely see the choppiness and green highlights, but in the back of my head I knew the schools TV's are of low enough quality to make something like that unnoticeable. I finally found the rest of my lights so I'll be able to go at it with more than the two work lights we used.

Heres some grabs to show the color:

On my LCD they look a bit light but on my CRT and CRT tv the green looks just like what I've seen on any "behind the scenes" DVD extra.
