Multi Masking and Keying
I have a guy wearing a blue dress shirt under his dark dress coat in front of a blue screen. The blue shirt doesn’t ever touch the blue screen as it’s surrounded by the dark dress coat, but when keying out the bluescreen with color range I lose the natural color of the shirt and part of it on the edges. Is there a way I can use the pen tool to specify an area I want to keep like “everything inside this mask do not key out” and then still be able to use a mask around the outside of him to get rid of everything else outside of that mask (boom mic)?
I hope I’m explaining myself clear enough.
By the way I’m never able to get very good keys. I always have to use a lot of matte choker and really soft edges. When I have hard edges they are squiggly. I assume it’s my studio setup with my talent being only about 3 feet from my bluescreen, but I have no other room to move them forward anymore. Any suggestions on that?

you can just duplicate your footage (unkeyed) and make a mask around the shirt.
the wiggly lines could be due to interlaced footage… in the interpret footage window make sure you are separating fields (select you footage in the project window and choose file>interpret footage>main, then choose the correct dominace, usually lower).
also it sounds like you are not using keylight… it is an effect on the ae install disk, in the third party folder. it would be worth taking a look at. barend did a tutorial on it. andrew kramer has another tutorial here.
aharon robinowitz has a good tutorial on creating supertight junk mattes, which is helpful too.

Thanks for the info. I have keylight installed but I’ve never really used it successfully as I don’t know how. I’ll check out those tutorials. But keylight was giving me really bad blocky edges and discolored skin tones. Like I said I’ll check out those tutorials?
As for the masking, thanks for the tip, do I have to keyframe the mask as the guy moves or is there a faster/better way?
Thanks

if you separate your matte, and use it as a track matte. then you may be able to use the paint bucket effect to ‘fill in’ the shirt area with white. you will still need to key frame the fill point to track the shirt… i’d probably try it manually, but you could try to track a point on the shirt and apply the tracker data to the fill point.
