Removing film grain makes compression far more efficient. This reduces costs of streaming.
- ethbr1 3y agoI find it hilarious that HBO's classic "snow" static dissolve is literally the worst clip for digital compression. https://m.youtube.com/watch?v=P_Oh7HizY5I https://m.youtube.com/watch?v=P_Oh7HizY5I Which I guess is why Max has a boring gradient.
- karmakaze 3y agoI could be worse if it had chroma information.
- ancientworldnow 3y agoIt barely makes a difference in reality. I've done final online conform tests for major distributors and the differences in savings vs perceptual cost (if delivering to a targeted bitrate) are negligible. It's also entirely moot for blu-ray delivery.
- masswerk 3y agoSo, here ist your comment with the grain removed (quote -> GTP summary -> GTP re-expanded to original length): > Removing film grain significantly improves compression efficiency, resulting in reduced streaming costs. Why didn't you word it like this in the first place? (Mind the compression efficiency: 18 bytes improvement over the original, 109 bytes versus 117 bytes gzipped.) ;-)
- SushiHippie 3y agoDo you mabye mean "GPT"?
- masswerk 3y agoYes. Anyway, what is more important to preserve: artistic choices made according to the medium (which importantly includes the kind of film stock for any movie) or bandwidth? And, if it's all about bandwidth, why do a high definition version, in the first place, and not stick to the low-bandwidth, but high fidelity 2K transfer?
