Past 1080p: When?

[J_UNTITLED]

There is a nice little local theater near where I reside that is an all high definition theater, using Christie 2k Super High Definition Digital Projectors. The result is a pretty stunning 2048 lines of progressive scan resolution which is obviously much greater than what most (if any) home-based HD technology can provide. I was just wondering, how far into the future do you think it will take before we start seeing higher resolutions being available on a Blu-ray-type of disc or device?

When Bush drops oil prices the people will be able to afford such a device.

well, considering that anyone that has a 1080p tv right now is way ahead of the curve. just look at plasma and lcd prices over the last 2 years and how they drop significantly after 6-12 months. my 5687w samsung purchased the week of x-mas, last year for $1799 is now available online for around $1199, 7 months later.

i'd say we've got about 2-5 solid years of 1080p stuff. once cable and movie makers upgrade to the 1080p format and it becomes more mainstream, then we'll see the new technology come out. right now i feel that most of the country is grasping 720p or 1080i on cable. this is new to them and they love it. as more and more people enter the HD world, then you'll see the new technology being introduced.

ever seen minority report, i sure that that type of technology is being refined right now.

It definitely seems like a possible possibility.

Actually.....what you saw was nothing more then 1920x1080. I know because I work at a huge post-production facility in Hollywood. Any movie that is shown in theaters is no more then 1080p, which is usually a DCI release. We usually also give the studios HD-cam SR tape (which are 1080p, 4:4:4 color) or D5 (HD, but 4:2:2 color). Even when I work with the 2048x1556 frame from a 35mm film, the projectors can only display 1920 across, which is usually fine due the soundtrack being on the left side of the 35mm frame. We are starting to do movies at 4k (4096x3112), which looks amazing. Its just really expensive to do it right now. Eventually that will be the norm. I know that 4k projectors are just around the corner, cameras are already on the market. But first, we just have to work on getting all the theaters converted over to digital projectors first. Then we can worry about a higher resolution....

As MPoozy has correctly stated, the Christie 2k projector is actually 2k lines horizontal instead of 2k vertical resolution.

For example, the Christie CP2000 Digital Cinema Projector, which uses the 2K 3-chip DMD DLP Cinema chipset is 2048x1080.

They now have the next generation of projectors that are 4K, I saw my first one 2 years ago at NAB from Sony, it uses SXRD technology and has 4K resolution, that means 4096x2160.

If you want full 3-chip 2K performance in your home, you can get it now with something like SIM2's HT5000. Of course it won't be as bright as a Christie and the optics are short throw and you won't have a D-Cinema source file.

[Deciazulado]

Yeah I've been saying all year that 1080p = 2K but apparently people still get confused by the horizontal/vertical way of describing them.

If you use a 2K scanner with a 82p/mm scanning beam pitch you get:

1.37 Academy 1250 x 1720
2.39 Scope 1440 x 1720
1.85 USA Widescreen 930 x 1720
1.85 S-35 1060 x 1960 (or 1040 x 1928 from some alternate aperture dimensions)
2.39 S-35 820 x 1960 (or 806 x 1928 from some alternate aperture dimensions specifications)

from the intended to be Projected Aperture image (The 2K scanner scans more than that as it scans the whole Camera Aperture)

The Academy, and the Scope's height have to be resized down to fit within the 1080p height of the 2K projectors 1080 x 2048 imager, Scope's width and 1.85 USA Widescreen should have to be resized up to fill it.

Remember that theater's Projector Apertures/lens/screen matting combinations usually crop a little bit of the image (kind of like TV overscan) and their aim should be to show the Projected Aperture specification dimensions.

So well said, it had to be said twice

As soon as universal backs blu ray! lol

i wish I could remember where I saw it (wikipedia?) but there was a bit about some (taiwanese?) researchers that were running an Ultra-HD rig, some kinda sick res #'s, like 3840x2160 or better. I remember they mentioned they played some test footage of riding a roller coaster, and subjects actually felt motion sickness since their brains couldn't distinguish from reality. Imagine that s&*t in 3D!!!!

There is a thread for this. Remember, the search function is your friend.



As Deci pointed out, the 2K and 4K Digital Cinema standards are not what people usually think.

2K == 1080 (v) x 2048 (h) @ 24 or 48 frames per second
4K == 2160 (v) x 4096 (h) @ 24 frames per second

As far as I know, no one is currently shipping to cinemas at large the 4K systems. There are some prototypes and units under special test, but none in any theatres for the general public.

[haushausman]

After a certain resolution can't the naked eye not even tell the difference?

[WickyWoo]

The human eye, at the size of screen you're likely to ever find in the home, would not find an appriciable difference beyond 1080p.

The next revamp of the TV system is 50 years off.

Japanese forum members will kick the shniznit out of you. It's NHK and their Ultra-HD 7680 x 4320 spec. They are still working on it as evident in this year's NAB.

If they can make it work, it'll be another 20 years before it becomes a worldwide standard.

Well, actually it has started.

Muvico released a press release back on Mar 14, 2007 that they will build the world's first theater complex with Sony's 4K SXRD(tm) projectors in all its theaters.

The location will be in the Chicago suburb of Rosemont, IL and all the screens will be equipped with SXRD projectors, the SRX-R210 10,000-lumen model and the SRX-R220 18,000-lumen model.

The location is expected to open in August with three more locations by 2008.

Dcinematoday.com has the press release.

Interesting. What do people think would have the most impact in the home:

2K@48 or 4K@24?

LMAO you mean when its election time again past couple elections senate,white house..exc it drops drasticly so it looks like there doin a good job then crank it back up to reep record profits

... anyway I hope 1080p stays around for awhile It sucks to keep having to upgrade

Depends on the size of the TV and distance to viewer, for example, if you were viewing Samsung's 108 inch TV which has pixels more than 1mm accross, I bet you could tell from up close, if you put your face about 30cm away, then you'd notice if the resolution were increesed.

But yeh, I doubt the 108-inch TV will take off for home use so resolution increases are probably quite a way off.

I think it'll be like HDTV is today, sports and live entertainment would probably be prefered at 48 fps with its higher temporal res while most narrative movies and maybe those scenic documentaries and travelogues at 24 fps to have the higher spatial res. Maybe some heavily SFX action movies would be prefered in 48 fps too..

Babylon5 and Star Trek had SFX at 30fps

Live TV of course is 60 (i or p dependig on res)

If you have a PS3 you can watch your movie BDs at 36fps if you chose the 1.5x speed. Do people like the increased temporal resolution look there?

Well a few members have screens that size or bigger already and they seem to love their movies there (I think the one that has a 140" has a 720 projector even!)

To me the 103" Panny Plasma is a fine enough size for 1.37 and 1.85 movies but It needs to be wider for Scope ones



Anyway the sooner we get 1080 as the standard of home theater the sooner well get 1440 x 2560 and 2160 x 3940 displays.
