to key or to roto ??
is that a question?
I have a cartoon character to use in a promo, he swings across a blackish background. I would like to cut him out to use him over my background. Rather than spend the whole day rotoscoping i was wondering if there was any keying tricks i might employ…. I had a quick go using color key which shows there is some diference in color between the backgorund and the characters outline , but only a VERY little (black vs dark grey). Nothing like a sharp edge is produced and the characters eyes are black as is his mouth etc…… I have not much keying experience so any advice as to how or to how not bother with is approach would be most thankfully appreciated……..
Big up you all
Chris

You should give Chromakey a try first, since it’s way easier…and play around with the “Matte Choker” filter…if you get any dirt in your clips, you could always roto out those specks after you chromakey. I think this is way easier than roto, since your background is not that complex.
It’s always good to experiment first.

definately try any save timing technique over roto work. remember that you can use keying to keep parts of your image, not just delete them, which may work to your favour depending on the colours/vision your working with. remember you can use multiple keys on the same piece of vision. remember if everything keys except the eyes for example, it’s quicker to garbage mask roto an eye back in – than to abandon every everything and roto the whole thing… and testing with a quick colour key isn’t the best indication of whether it will key or not. spend some time (5 mins?!) with each keyer (all work differently) and make a decision. if you’ve spent 1 hour testing techniques, but it’ll take you four hours to roto the dude, then it’s time well spent, whether it works for you or not.
