Netflix: 30% bitrate saving using Film Grain Synthesis
That's a gigantic savings, but not surprising since film grain (or noise generally) is the worst thing to compress. It's hard to think of any other single "feature" improvement that could result in such massive gains.I've always found it funny that the "HBO" branded intro to all their shows is produced of pure visual static. ([1] for anyone unfamiliar.) They literally couldn't have picked something worse to encode for streaming.https://www.youtube.com/watch?v=O08PQRA6MLo
