By my reckoning, 4k would work out at about 15 times the pixels of 1080p, so that won't be enough.
Anyone seen a 4k projector in action?

Then more layers? Pioneer showed off a 16 layer disc (around 400Gb) a few years ago.
If it works, sure.

Is this a method used to stop piracy as well?
It's 4 times the amount pixels compared to 1080p, which would still make it too big for a 4 layer Bluray, unless it was compressed with x264 which would make it around 45GB.
4 times in each direction, or nearly, so that's somewhere between 15 and 16 times as many pixels.
HiDef 1080P = 2,073,600
QFHD (3840x2160) = 8,294,400
Digital cinema 4K 4096 × 1714 (2.39:1) = 7,020,544
Digital cinema 4K 3996 × 2160 (1.85:1) = 8,631,360
Academy 4K 3656 × 2664 (1.37:1) = 9,739,584
Full Aperture 4K 4096 × 3112 (1.32:1) = 12,746,752
VonhelmetHD = 31,104,000 pixels
WTF so 1080p refers to vertical and then 4k refers to horizontal?
What utter marketing tosspottery.
Point rescinded and altogether conceded.
Indeed.
QuadHD is a good name for its resolution (double the horizontal and vertical pixels of "FullHD"). But with 4K you sort of think 4K vertical because everything has been marketed by vertical pixels (720i/p or 1080i/p).
Annoying huh?

Obviously the caddy is sealed, and designed to be tamper proof.
The caddy itself is propriety and won't fit in anybody else's caddy.
Plus the files themselves will be encrypted I suspect
Yeah I was pretty sure that's where you had made the mistake. However it is better this way due to the different ratios used, 1080p doesn't always mean 1080 vertical lines, but 4K will always have the same amount of horizontal pixels.
1920x1080 = 1080p
1920x848 = 1080p
3840x2160 = 4K
3840x1696 = 4K
It's also worth noting (from my experience of compressing blu rays to fit on BD25 sized discs) that current commercial blu ray movies are no where 50GB in size (even though they use a BD50 disc). The largest movie i've seen size wise was about 30GB, and then with lots of extras/hd audio tracks in different languages it pushes it to just over 40GB, and even then they aren't filling up the disc.
yeah , majority are now around 25 - 30Gb, I have seen a few approach 40Gb (I have about 700 BR's lol, with about 1/4 ripped to a server)
I havent heard /read any figures but it would be interesting to know what the LOTR EE's file size is for each movie (albeit across two discs)
Genuinely interested , but did you mean "wont fit into anybody else's pj" (rather than caddy fitting into another caddy)?
Obviously hopefully) there has to be a common link somewhere in the chain when 4k eventually comes down to home equipment, I just cant see where it wll be (anti- copy encryption on the drive itself so the caddy can be common between all makes?)

I actually have the 3 extended editions on my hard drive at the moment in my to do list. The sizes are as follows (based on just the film track a single HD audio track being selected):
The Fellowship Of The Ring
Disc 1 27GB
Disc 2 29GB
The Two Towers
Disc 1 27GB
Disc 2 33GB
Return of the King
Disc 1 33GB
Disc 2 35GB
Not bad!

No reason to change physical formats yet since it is possible for hundreds of Gb on Bluray anyway, just need the production cost to lower. The worse case scenario for the end user is buying a new bluray player or upgrading the optics on their current one apparently.
Switching to a different format just wouldn't happen, Bluray hasn't been fully established yet/replaced DVD, introducing a 3rd format wouldn't work. HVD wouldn't kill of Bluray as there is no reason for someone to change to it, it wouldn't sell.

Thanks for that - thought sizes would be pretty horrendous lol
"upgrading the optics" is essentially a new player anyway - if these super discs were ever going to actually appear I think they would have done by now (given that they have been working in labs for several years)
Even if they were able to get BR to store 200Gb /disc (which is the largest Ive ever heard of in experimental conditions) its still a factor of 10 out for a 4k film (which would require Tb of storage rather than Gb)
If BR struggled to start with (and in some respects still is), the very limited numbers of those interested in 4k wont make any format economical for years to come, even with 4k projectors and tv's already on sale now the best we can hope for is massively upscaled software to watch on them (and while I believe Japan has 4k tv services, I cant see UK getting even full HD service for donkeys years yet lol)

400Gb a few years ago and around 600 now. Like i said, just a matter of making it cheap to do and we have the time, 4k isn't exactly round the corner.
How is a 4k Film going to be larger than that? Considering the sound will probably be the same and the resolution is 4-6x the size.
