Tech Papers 2023: This paper details a subjective study that found current film grain synthesis methods in video codecs, such as AV1, are suboptimal and fail to consistently preserve the filmmaker's creative intent, highlighting the need for a better objective quality metric.
Abstract
Despite the advancements in digital cinematography, numerous artists and filmmakers still adore the look and feel of the content that is shot on film rolls. Specifically, they believe in true film grain as a signature of motion pictures and thus they treat grain as a key part of their artistic intent. The natural randomness of the true film grain comes from the crystallisation of silver halide when exposed to the light, and this natural randomness of true film grain is what fascinates content creators. However, content distributors like OTT providers and streamers always have trouble ...
