So I am trying to create a "Pleasantville/Sin City" look where there is a shot that is all black and white except for the red tip of a lit cigarette. I found a guide for how to do this in FCP, but I use Vegas, so it was not very helpful. It recommended that you selectively desaturate all but the color of the thing you want to keep (a balloon in the example, I would put a link to it here, but i can't find it and search is disabled while servers upgrade....) but I could not figure out how to do this in Vegas. Is there some way to do it that I don't know? Is there some better way to get the effect in Vegas? I assume it has something to do with masks and parent/child relationships and all that Jazz, but I am pretty new to the program and haven't figured much of that stuff out yet. Any help would be really appreciated. Thanks!
