HEVC can compress it to about 4GB. At 10Mbps cable internet (typical in urban Comcast), it would take ~1hr to download 4K 2hr movie at this compression. This is what makes realtime 4K streaming possible.



HEVC isn't 4x better. 4-5Mbps 4k HEVC is going to look bad under a whole lot of conditions.

And 17Mbps 4k h.264 wasn't a great place to start in.


Doesn't Netflix already stream 4K content using HEVC?
