AV1@Scale: Film Grain Synthesis, The Awakening

Everything is fake now. I want a technology which works with a raw film scans, not even compressing them to JPEG, which is a 1st step in loosing the details BTW. Motion detection, key frames, delta frames - fine. But with a lossless video. On a Blu Ray off course, i don't care much about streaming.

I wonder how much you'd get with such a technology... truly uncompressed 4K video you're talking about something on the order of a few terabytes for a 90-minute movie, so way way bigger than the biggest 4K Blu-ray discs. Lossless compression would get you under that number, but far enough to matter?

A 4K/24p film encoded with Apple ProRes 4444 XQ (not even ProRes RAW) is 716 GB per hour, so you would need to swap a total of 30 Blu-ray discs once every 4 minutes in order to watch a 2 hour movie.

UHD discs used for 4K movies today already store much more than 24 GB per disc.
