Project mention: AV1 @ Scale: Film Grain Synthesis, the Awakening | news.ycombinator.com | 2025-07-03
Ok, very cool. But I want Netflix to explain it related to Seinfeld, which at 10-12 feet looks fine, but up close looks insane. Blocky MJPEG + grain filter??
It's not like we're on Pentium II processors anymore -- I can filter just about anything with ShaderGlass [0] on a shitty computer (and some of the CRT shaders like crt-hyllian-curvature are brilliant, especially on old shows like NewsRadio that only exist on DVD) .. and I'm shocked that Netflix doesn't just have this built into their Apple TV app or whatever. I'm shocked PLEX doesn't have it! (that I know of)
I made a comment on a different post about imagining a world where local AI/LLM/whatever does some favorable processing for you, by you, on your device, of web content, to enhance your experience. I really believe media (streamers all the way down to open source devs) need to begin to incorporate whatever's out there that reduces friction and increases joy. It's all out there already! The heavy lifting has been done! Just make Family Matters look like how it looked when I was locking in on a Friday night for TGIF LOL
