Provided are a computer program product, system, and method for processing a source video stream of frames of images providing a first type of output format to generate a supplemental video stream used with the source video stream to produce an output video stream having a second type of output format. A modification is received to a luminance of a group of pixels that forms a distinct image that appears in at least one frame in the source video stream. The received modification to the luminance is applied to produce a first modified video stream. The color values for the pixels in the images in the frames in the first modified stream are transformed to different color values to produce a second modified video stream, which is merged with the corresponding frames in the second modified video stream to produce the supplemental video stream.
