mattes ??

[wan2no]

there was a music video i saw where different parts of the video was filled in colour and the remaining parts were gray scaled. I know it has something to do with matte manipulation. I'm not too sure, but i think if i wanted to make 1 person in a video coloured and the others grayscaled i would shoot the video twice and then use a difference matte. So if that's the case how would i get certain things like someone's pants or shoes in colour and the others grayscaled

Difference mattes are good when you can do locked-down tripod shots or motion-controlled (and repeatable) shots. The former is probably within your range of expertise and economics, the latter not likely.

My guess is that, green screen use notwithstanding, you would have to manually select the regions to saturate(colorize)/desaturate and then hopefully have software that can do motion tracking for subsequent frames. I know in AVIDs you can do a rough version of this. There are probably some additional plugins that would assist with the knockout creation and tracking/tweening, but I don't know which ones.

Of course, you could always try a quick & dirty chromakey!

Have a look at this tutorial from the generous folks at Wrigley Video : http://www.wrigleyvideo.com/videotutorial/tutdes_colorpass.htm

In this instance they use Premiere, but the technique should work in other packages.

that seems really interesting but i'm wondering how would i do that in sony vegas. there is no color pass plugin and i don't know how to single out a person and apply effects to only that region. Unless i use mask but that's gonna be alot of tedious work

All effects like this are tedious, regardless of package
