NAME

blind-set-saturation - Multiply the saturation of a video

SYNOPSIS

blind-set-saturation [-w] saturation-stream

DESCRIPTION

blind-set-saturation reads a video from stdin and a mask video from saturation-stream. The video is printed to stdout, with the saturation of each pixel multiplied by the product of the luminosity and the alpha value of the corresponding pixel and frame in the mask video.

If stdin is longer than saturation-stream, the remainder of stdin is printed without any changes. If stdin is shorter than saturation-stream, the remainder of saturation-stream is ignored but may be partially read.

OPTIONS

-w

Instead of using CIE Standard Illuminant D65 as the whitepoint, use the X and Z from each pixel in saturation-stream for the whitepoint.
