4K Blu-ray quality video requires a 144 Mbps bit rate. On a triple layer Blu-ray Disc (100GB in size) that nets you ~90 minutes of run time. That doesn't include audio, which can require extraordinary amounts of space as well.
For comparable quality 8K recordings you need 4 time as much space as needed for 4K.
8K won't be the stopping point either.
- kemotep 3y agoCodec plays a huge role here. By your calculations the 4k blu-ray box set for Lord of the Rings, Return of the King would take 5 triple layered disks (for both the extended and theatrical versions it comes with) for just the video and no audio or anything else like the behind the scenes content when the box set only comes with 9 disks for all 3 movies. Likely not using the full bitrate you provided but still. Hard to say they aren’t getting really high quality content on the screen.
