Unfortunately I do not have an example because I do not know the name of the technique.
I have seen in films at a local film festival an "effect" that makes the video black and white. I don't mean grayscale; anyone can make a black and white movie. What I mean is only black and white.
I know how to do this in programming with individual pictures. Get pixel color, and if its average RGB value is above 128, its white, and vice versa.
How would I do this in video? I personally have Sony Vegas Pro 13, and a friend has Adobe Premiere Pro CS6 that he can let me use.
I can add more info if needed, and I'll try to find an example.
