Video Shoot Advice

I'm going to be shooting a music video this weekend. I will be shooting the band against a green screen.

They want to be silhouettes against the green screen. The green screen will be different images from their abbum art and other images added in post.

I plan to shoot them from about 12 to 15 feet away from the screen. The screen will lite evenly. Will I be able to get this effect without much tweeking in FCP 4.5 and/or After Effects 6.5??

Should I also consider positioning lights directly behind each member?

Any advice before this Saturday (Feb. 4th, 2006) would be great.

Thanks guys.

I'm thinking it will be rather easy to achieve in FCP but I'm away from my Mac now and can't remember the exact settings. I'm thinking that once the background has been keyed out, it should be easy to make them into silhouettes by simply darkening them a lot. I also believe there is a matte that will do that somewhere in FCP.
You could also under expose them in the actual shoot, but I wouldn't since it gives you more freedom in post.
If I understand correctly, you want them to look like the people in the iPod commercials, right?

Do they want to be dark silhouettes in front of the screen? If so, you could keep them unlit so there is greater contrast between the musicians and the greenscreen. You could also add negative fill in front of them to cut down reflected light from the greenscreen. If you go this way, you might be able to pull a key from the luminence channel instead of chroma where there is less data. I don't know if FCP or AE will work with both the luma and chroma channels for the key, but it could be even better than just chroma.

Thanks guys.

I just have this fear of not being able to properly key the background. We use ultimatte at work and it rocks. It's a pretty heavy render though.

I was hoping that FCP would be strong enough. It's only a 30 second clip, so I should be OK regardless. A.E. will be able if not.

It will sorta' be like the iPod commercials. They want it more moody...less cartoony.

Thanks again.

It sounds like you have access to After Effects 6.5. If you do, I'd recommend just doing the keying and compositing in After Effects, as that's exactly the kind of use it was designed for. You'll have to forgive me if I'm a little off, i'm just trying to think this through by memory, but I think to get the effect you're looking for it should be a matter of bringing the footage in, keying out the background, then to get the silhouettes you're looking for, apply the keyed footage as a matte to a black (or whatever color you want the silhouettes to be) solid layer.

Shouldn't be to hard and will be a good little learning excersise.
