So you want to change the skin tones in a shot by doing a secondary color correction. You're using the methods outlined in ASC #16 (and of course, they work incredibly well!), but there's that nasty balloon in the shot that has a skin-tone-like color but that you don't want to affect.What you need now, my friend, is a garbage matte. A garbage matte restricts the key to applying only to a specific section of the image. I hear you say: "But can it be done in Media Composer?" I say: "You bet your ass it can be done! And in real-time, too!"So in this show, we'll build a secondary color correction with a garbage matte using the Spectramatte, a Paint Effect and a Matte Key.If this isn't cool, then I don't know cool. Oh. Wait.SHOW NOTESThanks to Alexander Fell who gave me the tip on this one:http://www.xing.com/profile/Alexander_FellDo check out the older tutorial on Secondaries, it uses a Boris Continuum Complete Effect and is generally more friendly towards the not-die-hard-geek:ASC #16: Secondary Color Correction in Media Composerhttp://avidscreencast.com/asc16Check out the blog entry for this week's episode:http://avidscreencast.com/asc40Follow me on Twitter:http://twitter.com/avidscreencastBecome a fan on the Avid Screencast on Facebook:http://facebook.com/avidscreencast
