Abstract
An encoder may signal a plurality of sets of film grain parameters for each frame of the video content, with each set of film grain parameters corresponding to one of the film grain resolutions. The encoder may also encode the video content into a coded bitstream with the plurality of sets of film grain parameters for each frame. The decoder may receive a coded bitstream comprising a frame of video content, and a set of film grain parameters for the frame. The decoder may decode the coded bitstream to generate a decoded frame at a decoder resolution. The post-processor may apply the set of film grain parameters to the decoded frame to generate an output frame containing film grains.
