I have a client who has some footage of a guy in a blue shirt, in a background that's blue, and it's not even full blue, it's a Photographers muslin background, and she wants me to Key him. I showed her how he'd look, with his floating head and arms after all the blue was gone. She then asked if I could change his shirt color.......and I had to explain about the whole blue thing goin on. Then she asked if I could matte out the background.....and that I wasn't sure on. It's an interview, he's sitting there talking. Can I get an alpha background someway, somewhere with this footage? :-)
Wow, a client that thinks you can do this easily? Were they on the shoot? Did they change their mind after the shoot to key the background? I have some tough clients, but damm. I agree, not much to do outside of frame-by-frame rotoscopting and then it won't look perfect.
Thank you for the info. No, she wasn't on the shoot, but the ones who were, believe it's possible too....which I find a bit disturbing. I've shot and keyed for green screen, and I know the difficulties there, with even having il-lit spots and shadows.....nevermind same colors. ;-)
