keying out entire characters not in front of greenscreen
i’m trying to figure out the best way w/o rotoscoping to have characters in a shot become complete silouettes…the locked down and closer up stuff i’ll do in front of a greenscreen, but there will probably be shots that have too much movement or are too far away to do this way. would it be at all reasonable to dress the characters up in a completely orange (or whatever color i’m not going to find in the shots, mostly exterior and dimly lit) and then key them out? any better ideas on how to do this? thanks.

i hear you, but i’m going to have shots where i’m driving past the characters from a longer distance, them running across of a field, etc…stuff won’t look believable if i’m just placing the characters into the shots from a different comp…shooting the screened stuff won’t be a problem, but i’m wondering how/if i should try the shots that won’t be on a greenscreen. thanks.

yeah it will probably be a pain…i’ve been experimenting with some footage i found of a nascar pit team wearing all red, keyed that out and it works better than i’d thought b/c the shadows blend into the back abyss anyways…also, i want it to kind of have a weird look to it, not so much silouettes i guess, and adding a heavy dose of the screen pre-blur helps take out some of the problems. i’ll do some tests and see how it looks. thanks a bunch for the suggestions.

I agree, you’re going to need to do some rotoscoping. But, it can be reduced to a minimum by duplicating your footage and keying out different pieces of clothing/skin on each layer. Just keep adding them up until you’ve got your entire figure keyed, then make it a track matte, and select inverse alpha and you should be good to go. Clean stuff up with a little roto and garbage masks. There’s no reason to feel you have to dress your people in one solid color…just keep keying away until everything is gone. Not that you’re thinking this, but many people feel they should need to have the key based on one single color. That would be great, but in practice a good key is a sum of several.
I hope it all works out for you.
