Monochrome

Sapphire’s Monochrome filter¬†generates a monochrome version of the source clip using adjustable weights for the red, green, and blue channels. This can simulate the use of a color filter applied to the lens of a black and white camera. For example, use more red weight to darken blue sky areas of the input. The weights are scaled so they sum to 1 before being used to reduce overall brightness changes when they are adjusted.
