Claim 5:
6. A method, comprising:
performing, by a film grain description estimator implemented by one or more computing devices:
receiving an input video comprising film grain; and
analyzing the input video to generate a film grain description for the input video; and

performing, by a video encoder implemented by one or more computing devices:
receiving the input video;
configuring, responsive to a determination the input video comprises film grain, one or more encoder settings to de-grain the input video as part of encoding to achieve a compression target;
encoding, according to the configured encoder settings, the input video comprising film grain to de-grain the input video to produce encoded video achieving the compression target; and
sending the encoded video and the film grain description to a video destination.
