So as you can see here, the black collar of his jacket makes a very strikingly bad cut in the key. Is there any way to fix this problem without resorting to a frame-by-frame mask? I'm on AE CS5 and using Primatte Keyer4.1. I'm pretty familiar with Keyer's tools, but I'm at a loss as to how to fix this problem since it even looks weird in the source footage so I can't think of any way to get the keying tools to think about this area of the footage differently than the rest of the key and, of course, I'm on deadline and don't have NEAR enough time to frame-by-frame this issue. Any thoughts would be extremely appreciated!
.....From yor photos is not clear to me what you will like to achieve if the source allready looks weird in the source footage. Although is the green screen reflection that causes the problem you can try to have a clean matte through Mocha...etc.
