I don't understand 4K blu ray. It's 4x the resolution of HD but only has ~2x the storage capacity of blu ray. Isn't that limiting bitrate/quality?

- xeromal 5y agoUHD Blu-Rays can go up to 100GB in capacity and can be read at 144Mbits/second. I don't think it limits many movies, but my 4k Lord of the Rings copy has the movie split into multiple discs.
