Abstract: Film grain is spatially random in nature, while its physical size can also vary. In addition, film grain is independent in a temporal domain, thereby making it inherently difficult to compress. Therefore, to improve a video coding gain, the film grain is removed prior to encoding, and then added back after decoding at the post-processing stage, as is currently implemented in the Alliance for Open Media (AOM) AV1 coding scheme. In this work, the AV1-compatible film grain modeling for the High-Efficiency Video Coding (HEVC)-based video codecs has been carried out to utilize the existing AV1 film grain post-processing support efficiently. This is done by providing estimated film grain parameters within the International Telecommunication Union-Telecommunication (ITU-T) Recommendation T.35 (ITU-T T.35) Supplemental Enhancement Information (SEI) message. According to extensive experimental results conducted on popular cinematic content, significant bitrate savings are achieved.
