Back of the envelope estimate:
4096 x 2160 x 24 x 60 is your theoretical max in bits/second, 127 billion.
Assume that to counter YouTube's compression we need 16x16 blocks of no more than 256 colors and 15 keyframes/second; that reduces it to
256 * 135 * 8 * 15 = 4.1 million bits/sec.
That's not too awful. Ten minutes of this would get you about 300MB of data, which itself might be compressed.
- pstrateman 4y ago4k video is almost always 3840x2160
- kuschku 4y ago4K consumer video is 3840x2160, 4K Cinema video is 4096x2160. Just like 2K consumer video is 1920x1080 and 2K Cinema video is 2048x1080
- pstrateman 4y agosure, youtube videos are consumer though
- kuschku 4y agoNot necessarily — YouTube supports DCI 4K as well and videographers sometimes upload in DCI 4K.
