I've got color video that I want to fade in to black and white but keep it running without any transitions or what not...just a fade away of the color...
Can it be done?
Well, well, well - here you got three very different methods, all valid, all easy to do. All perfectly meeting your requirements. That says a lot about Vegas, but also about this forum. They're both great.

I haven't tried this, but I believe I read somewhere that it's better to use the b/w filter than to screw with the color settings- I believe it effects the render time...
