Black-White/Color Effect in Doomrider project

[Jord]

I've got a question about a effect in the Cell games part of the Doomrider project, but it's also in other bits of the video I think.
Anyway, the entire screen is displayed in black-and white except for a small part, in this case Gohan's head with Goku's hands upon his shoulders at the 5.43 mark. Later we see Gohan in color with a black and white background.

How did you do this? Did you simply cut the frames or is there a special way/effect/magic trick to realize this?

There's no magic to it. It's frame-by-frame masking. Our friend Jeff actually did all of the "special effects" in our Cell Game track, and I know he did it all in After Effects. Pen tool, masks, etc.

He very well could have used the "color key" effect. It's when you can change the color of certain user-defined colors. He may have used it multiple times to gray-out multiple colors. Masking's a definite possibility, too.
