That will NEVER happen. Not in my lifetime. 3.5 Terabytes and only 18 mins of footage? That's cool for engineers, but the only likely useful application will be cinemas. They would have to have huge server farms to do it though.
It's been several years since I last ran across a story about it, but Fluorescent Display technology was promising, around 2000 or 2001, to develop a 5" disc with a sufficient number of data layers to offer a terabyte of info on a single disc. At the time I think they had only successfully replicated a disc in the tens of gigabytes, a few times greater than a DVD-9. It uses fluorescent light to read the data.
If 18 minutes requires 3.5 terabytes, a feature film (say 90 minutes) would come in around 17.5 terabytes, give or take. That's 17 or 18 discs. Ack. But if larger 10" platters were developed, and that claim by fluorescent tech's developers could be met, you could get that down to 9 discs ... this still isn't feasible as a practical technology for the home, but if a successor to fluorescent (I believe the acronym for the technology is/was FHD?) could triple that capacity, you've got three discs. Six for a three hour film. A carousel changer (for 10" discs) could potentially hold that.
Decades away? You bet, unless an unexpected tech breakthrough is around the corner. But if UHDV could be successfully and transparently compressed, holding much higher resolutions in a much smaller space (as the Windows Media Player 9 codec used for the HD edition of Terminator 2 on the EE release compresses HD onto red laser 5") ... hmmm. Compress UHDV by a factor of 5, and you can get a 90 minute movie on three or four 5" terabyte FHDs. Compress it by a factor of 10, and it all fits on two discs .... Well, I see the potential here for advances in the next twenty years to make such a thing conceivable. Just ten years ago I was reading articles insisting that anything more than MPEG1 Video CD tech was a decade away. But DVD (with both greater and more reliable compression and greater on-disc capacity) has been here six years already, and HD-DVD is promising a still greater on-disc capacity and greater compression as well, perhaps by the end of 2005.
This has nothing to do with photochemical film, of course, but a native UHDV project compressed by some future codec and contained on terabyte discs ... well, that'll be the day. Home displays equal to the resolution will have to be commonplace as well, but I can see filmmakers embracing this sort of thing. Lucas first, others later. If he continues making films after Ep III, that is.
You're thinking of FMD (Fluorescent Multilayer Disc) from Constellation, a technology that was predicted to be able to reach the TeraByte range easily, with a possibility of getting up to 100 layers on a single clear (but thick) disc.
I'm not sure what the status of FMD is these days...the buzz about it has died off. This article from 2000 (the year FMD was shown at Comdex) has a pic of a disc and a link to Constellation's website...but the company site doesn't seem to be there anymore.
Hitachi was reported to be working on their own technology - planned to hit market in 2007 - that would surpass FMD in capability, by all reports. They are still being ultra-quiet about it, though.
Nevertheless, I think that A) memory storage for this project is high right now, but they will find ways to reduce the needed space for the same quality, and B) technology is coming that will allow the needed capacity to be stored.
As to the UHDV technology itself...what can I say but this:
This can only mean one thing:
In the future, George Lucas Jr. will have to re-shoot Star Wars AGAIN because the computer generated special effects will look really really bad on a UHDTV.
Seriously, movies are gonna look sweet when my children and grandchildren watch them.
I'm curious what projector they used for the tests.
Many thanks to Dave for those links -- FMD was, indeed, what I had in mind. I hadn't heard of the Hitachi project.
Keep in mind that all this footage is uncompressed -- I'd be surprised if NHK has even begun experimenting with compression yet. Given that 4,000 lines of resolution would have a lot of redundant information you could conceivably have 50:1 or even 100:1 compression with no visible loss in quality. Sure it'll still have huge storage requirements but it's not quite as daunting as it seems.
You must be old..
The thing is that, when we had little memory, we maximize its full potential, now that we have lots, we waste it.
This is just amazing. I wish I will see the day that this happens, and have the mental capacity to to enjoy it.
I won't be happy until the actors are in front of me, acting the movie live!
It would make horror movies very interesting. (not to mention porno :b )
LaMarcus - even better...combine the two! Moohahahaha!
