Person appear in black and white

I wish to film a person either walking and standing still to camera with static and moving backgrounds.
How do I make that person appear in black and white and maintain a colour background, please?



Thank You

You can shoot the person against a green/blue screen, then key out his background. Otherwise you'll have to use a garbage matte to cut out the guy and turn him black and white, plus motion tracking. Not a Final Cut Pro specialty.

Derek -

I think FCP will do this, but Peter threw in an additional layer of complexity by asking to make the subject be B&W.

I have had excellent luck using FCP's built in Keyers (Chroma and Color under Video Filters>Key). if you change the image to B&W, then we no longer have a green or blue screen, we have a grey screen.

My approach might be to try using two or three copies of the clip... do the chroma key replacement on the one clip... make a mask of just the subject on another clip, then make the subject be B&W on the third clip...

And try to layer them together in the right order to work.

Is this (or not) related to the Pleasantville effect referred to here from time to time?

He can probably use an inverted Color Corrector - Limit Effect to target everything *but* the green for desaturation, then key out the green.

Re my subject question - thanks to all who repolied - I will try out the suggestions.
