It's 1080 but with ridiculous bitrate 150Mbit/s
Usually movies encoded at 15Mbit/s
Especialy with all this DOF it's pure overkill nonsense ,you lose all high frequency that 150Mbit/s make no sense even for PBR/PBS CGI
Non DOF Versions would be nice
VP9 Versions would be interesting as well
I mean 150Mbit/s would only make sense if your Encoder isn't capable compressing it better which would only count for Streaming Solutions like Nvidias NVENC that wouldn't be capable of keeping the quality high enough most probably with this content, though the heavy use of DOF should help a lot even with such bad Encoders.
