Chroma key question

Hi-

I'm shooting some green screen footage with my Canon XH-A1s, 1080i HD. The footage is going to live on the web in a Flash movie and on Youtube. I'm running After Effects CS4 on a MacPro with 16gb RAM.

I'm curious to know if anyone can suggest the best Render settings to use. I'm getting better at the deinterlacing and color correction but with all of the settings that AECS4 has I'd love to learn how others have succeeded with rendering the footage, especially with needing to put it up on Youtube and using Flash.

Any feedback will be greatly appreciated!

Thanks,

Rich

Do you need advice on keying out the green screen or on outputting a high resolution file? For chroma keying, I use QT Animation codec or BitJazz SheerVideo, because either supports an alpha channel. I usually crop my composition down to the "active" area of my green screen subject matter, using a frame size that's a 16x multiple.

Thanks Robert. I was actually just looking for file format details, but I'll look into that BitJazz codec as you're not the first to recommend it to me. Thanks for the tips!
