everything in B&W except for what's moving

Hi,

I'm trying to create a jitter effect in which whatever is in motion in the shot remains in color while the background / motionless stuff appears in black and white (or vice versa). Can anyone give me a hint or two to point me in the right direction?

Cheers,
Jay

search for "background subtraction" or something similar on the forum.
that would be a good place to start.

And then look into jit.rgb2hsl/jit.hsl2rgb.
