4K 3D Movies Not Included in Ultra HD Blu-ray Format ?

I literally don't understand your point so my question was a way of trying to summarize my (mis)understanding of what I thought you to be saying and ask a clarifying/summarizing question.

Perhaps I misunderstood you to be referring to the longer amount of time it will take to write a compression codec for this greater amount of data when--as radagast's post says--what you were perhaps instead referring to is just the greater amount of data (and the larger amount of space it would take to store a larger amount of data using the same codec?).

I didn't think 1080 3D required a different codec? My understanding is that frame packing, side-by-side and top/bottom--the way the data is presented/organized--is what enabled 1080 3D, not a new, more efficient codec. Why couldn't that be done here? Or are you saying it could be but it would just illicit complaints because it would require multiple BD for one 4k 3D movie?

I understand from Richard Paul that the issue is HEVC development. And I also now understand that HEVC developers can't write a codec for a format that doesn't yet have a spec (4k 3D). So I guess what I'm saying/bit*hing about is why can't/couldn't the BDA codify the 4k 3D spec contemporaneous with 4k BD such that the Whole Enchilada could launch at the same time. If the answer is "it's so much more data," then you see the circular issue/conundrum I'm trying to describe.

If the argument is that it would delay 2D 4k BD, I think the argument could also be made that it stymies 4k 3D BD adoption to roll it out some 12 to 18 months after 4k BD. I'm literally right now in the midst of speculating how long this is all gonna take . . . should I sell my 82" Mitsu DLP sooner rather than later especially since I'm moving again soon . . . but if I buy a 4k display now will it play HDMI-nice with 4k BD much less 4k 3D . . . if the format even gets codified are the studios going to even support 4k 3D BD . . . blah blah blah. I just wish this all were easier (I know, I know--'welcome to the hobby.').

No, you completely missed my point. To put it simply if 4K 3D is added or not to HEVC it would be meaningless for home distribution which is why I never discussed HVEC.

To put it simply if 200 GB+ disks were being introduced with 4K maybe it could be interesting with HVEC depending on how well HVEC does but with a 100GB being the max capacity that todays tech can master for disk capacity either it would need to be so overly compressed (to fit the film on the disk) that upscaled 2K 3D will be as good (if not better) and so it is worthless or more or less every film will need to be split on two+ disks which is something that consumers would not want (could you imagine the flak a studio would get from many people if 45 minutes into a 90 minute film someone needed to get up and change the disk?) and so studios would not use it.


Pie in the sky is all good on forums but people need to be realistic and things need to conform with what technology can offer.
