I guess that means one movie a month for some people  |

Does anybody stream 1080p uncompressed ? |

kudos:1 | So instead of 1.5G containers, we are looking at 3G containers. If you even care for that level anyways. |

Oh, please! 100 GB? A properly encoded 1080p H.264 movie can be stored in a file between 5 and 10 GB in size. 4K is about 4 times 1080p. That means a MAXIMUM file size of between 20 and 40 GB for a 4K resolution movie.
And that without considering the compression abilities of the upcoming H.265 standard, and the fact you can get away with applying more compression on higher resolution material!

That is without compression. You can compress a blue-ray 25GB to 3GB with x 264 |
|
| very true, though to be honest if someone is so overkill that they want 4k right now or within the next 2 years they probably will want a bigger file since whats the point of spending like $20,000 on a tv soon and then compressing the video? |

You can compress a blu-ray to 50MB, but it'd look horrible. So would it too at 3GB, which is not even enough for decent quality 720p.
Decent looking 1080p would require somewhere between 7 and 15 gigabytes for offline fully VBR video, depending on the content.

I posted about this in another thread, but the guy is basically talking out of his ass. 100GB is incredible overkill for streaming 4K... that bitrate is excessive even for an optical format. I suspect that when we eventually see a 4K variant of BluRay, which current holds u to 128GB on currently shipping discs, it'll use a lower bitrate than what this guy is proposing. Not that much less, I'd expect 4K bluray to use about three quarters of the bitrate that this Sony guy is talking about, assuming his 100GB is for two hours of video. --

All this talk about 4K streaming and everyone is forgetting we live in Canada and will never be able to do this because our ISPs would bitch and complain |

4K streaming at reasonable (for streaming) quality should easily be possible with existing connections. I'd expect you could do decent 4K video with a 15 Mbps video, well within the capabilities of today's 25 meg DSL and 30 meg cable connections. For people on 10 meg internet, a service like Netflix could have a lower bitrate 4K or almost-4K option that would probably still look OK, and it would seamlessly scale back (much like how there are a whole bunch of "HD" bitates for Netflix other than just 3600 and 5800).

Yes we can do it, you can test by yourself with youtube.

My old Xeon processor is not fast enough and have an hard time to decode it, but the streaming itself is perfect.

4K video should be well within the capabilities of a good multithreaded decoder on a decent CPU made in the last few years; I doubt the Flash decoder is either (good or multithreaded). Some new videocards have 4K accelerated video decode onboard that Flash could leverage, but support seems scarce.

Next to no movies are shot at 4k, vast majority will be upscaled file size bloated bs. This all assumes one has went out and bought a 4k tv, which will be say 50" or so, still not large enough to take advantage of native shot 4k content. My advice for consumers and 4k media is not to fall into this pointless upgrade money trap. |

Almost all movies are shot at 4k or shot on 35mm and scanned in 4k. Only low-budget stuff or during the early phase of the digital transition (like star wars episode 1) would be shot at 2k (1080p).
My screen is 100 inches, and could definitely use some 4K lovin', but it will be a very long time before 4K projectors are even remotely affordable.

100GB is already considerably compressed:
3840 x 2160 x 24fps x 3bytes/pixel x 7200 seconds = 4TB
So 100GB is already 40:1 compression and that does not even include the soundtrack... so make it 45:1 to leave some room for that, menus, subtitles, etc. |

Acceptable compression ratios do not remain unchanged as resolution increases. The higher the resolution, the higher the acceptable compression ratio, for both perceptual and camera optics reasons.
BluRay allowed a minimum ratio of ~30:1 compression (although in practice it varies and is often closer to 60:1). So a 40:1 ratio for 4K is incredible overkill. The bitrate at 100GB is roughly double what it needs to be for a 4K bluray.

You're over accounting for the audio. Uncompressed 8 channel 32 bit @ 48KHz would take 10Gb for 2 Hours, that's 0.25% compared to the uncompressed video. Sure if you were to carry it uncompressed you'd get 10GB of the final 100GB so that's 10% of the file contents leaving 90GB video for a compression of 44.4:1, but I assume that sony would use at the very least loss less compression to such an exaggerated audio spec. |

Most movies come with multiple audio tracks, multiple subtitle tracks, animated menus, extras, commentary tracks, etc.
Also, you need to add the MPEG framing overhead. |
