Trial and error pretty much on this one. I find you need to watch for reflections on the floor/hair, bounce/spill on your subject, avoid creases or folds. Then use a light meter to get your background as flat as possible. Do tests.

Definitely lots of tests. I dread any full-length GS shoot unless I know the client has the understanding, time, and money to allow me to do what's needed to make it look correct.

You will probably be battling green refection on the wood floor if it has any kind of finish on it. If you have a fabric GS, getting the edge to look good will be a concern. If your talent is in any type of dress shoes, beware of the reflections in the shiny black shoes. If you didn't notice it on the shoot, you WILL when you pull a key.

In a budget studio setting, full length GS can be a bear. If you have good studio resources and a good grip & lighting control package, it can be easier to green the floor and put a wood texture back in after the key is pulled. But you have to be able to dull shiny clothing surfaces and light with precise detail to avoid pulling your hair out - and also to sell it to the client.

The previous comments have said it: test/trail and error. To be honest, I think it would be easier to do a fully full-length green and then just composite the floor in. Without a camera that captures 4:2:2 or better colour space, full-length compositing can be nightmarish.

If you've got some good tools like Primatte or BCC Chroma Key (& BCC Key Choker / Matte Cleanup) it'll turn a Kodiak into just a simple black bear. :-P

I'd agree with Andreas

That's what I was thinking Andreas, but it is an exercise video and the talent is going to be moving. I have a cloth screen so even with it being taped down securely, I'm sure I'm going to get wrinkling. I'm going to try and convince the client to use some other type of background other than the green. Thanks for everyone's help.

Oh man. Well, here's my best-of-a-bad-situation recommendation: do the shoot twice if you have time. Do it with the wooden floor, and do it with a full green screen. Maybe run down to your local video/camera shop and see if they have some green paper for the ground.

It's not much of a solution, but having both types of footage will allow you to make the best of a bad situation if the in-situ floor doesn't work. Y'know?

And while this sounds like hyperbole: my heart goes out to you. Green is great if you can capture full colour space (which is what they do in film - which is why every guy and his dog think it's easy).

I won't have the opportunity to record it twice. I am going to tell him he can't have it the way he wants. If he wants green screen, he'll have to rent a studio that has a cyc wall. I will be shooting it with an EX1 which I believe is 4:2:0.
