Is Blu-ray future proof?

[saljr]

At this moment 1080p now but what happen when it goes to 1440p or 2000p.What I'm trying to say is If I buy a BD-DVD player for home use or a BD pc player. Will I still be able to use it in the future.

[HDTV1080P]

The experts are saying BLU-RAY will be around for 10 years. For example DVD has been around for 10 years 1997-2007. 480P has been the standard for 10 years for prerecorded optical movies. In theory BLU-RAY 1080P most likely will be the new standard for prerecorded movies for the next 10 years.
Possible in about 10 years holographic terabyte disc might start to replace BLU-RAY that offers 4K projection quality images.
To keep things simple and short 1080P is the highest standard in HDTV display technology. In about 5 years $100,000 2K consumer projectors should start hitting the market and then in about 10 years 4K consumer projectors should start hitting the market.
If you go 1080P you will not need to upgrade for about 10 years.

[theknub]

well, yes... you would be able to in a way...

however, when/if those standards are adopted, you will have something like upscaling dvd players but for BR. BR's can hold the data, but player standards would not exist that support that.

actually, 480i. 480p wasn't around for another little bit and even then it was like upconversion since the encode was 480i

Then BD 100 and BD 200 will come in charge...

Just a little note to mention that

1080p = 2k equivalent
2160p = 4k equivalent

So you don't think that there will be an inbetween solution? After all, 2k (2048x1556) has over 1 million pixel more to offer than current HD. And this would probably be possible on larger BD discs in the near future. For 4k movies we might need a new format (like the holo-discs).

Or is the difference despite the more pixels not relevant until we go really big with 4k?

I believe that nothing is future proof - entirely, although nothing stops anyone from using old technology.

Think of these, they all still work but are now obsolete:

Betamax (yes, I know studios still use them)
VHS
Cassette
Quadrophonic
8-Track
Wax Cylinder
Reel-to-reel
MiniDisc
etc etc

Now whilst these are generally commercially unavailable, they still all have their merits and are perfectly useable.

I guess that retailers will only sell software that the mass-consumer uses, why would they stock anything else?

Yes, because 1536 x 2048 is a 1.33 format, and movies are not done in 1.33 anymore.

A 2k scan of an anamorphic 1.20 shaped 35mm negative has more pixels than a letterboxed 2.40 shaped 800 x 1920 BD, and only in that case the whole 2k file would be advantageous, but as you can see, High Definition Consumer video has not gone into non-square pixels. (If it had, Scope shaped movies could have been encoded 21:9 1080 x 1920 on disc, but it didn't happen)

Also, true anamorphic shot movies are becoming less common, with producers usually opting for the Super-35 non anamorphic negative, specially for big blockbuster SFX movies.

So we are left with 1080 x 1920 frame

Four 35mm examples:

If you scan the T2 Super-35 negative at 2k (1536 x 2048), that means it's scanned at aproximately 2048 pixels across the full 35mm aperture width (the exact figure depends on the specific beam scanning micron pitch). That would make the intended projected image have a size of approx 820 x 1970 pixels.
So a BD 1080p 820 x 1920 crop of that = 2k scan

If you scan the Batman 1.85 35mm negative at 2k, that would make the intended projected image have a size of approx 930 x 1720 pixels.
So a BD 1080p 1040 x 1920 resize of that = 2k scan

If you scan the Casablanca 35mm Academy negative at 2k, that would make the intended image have a size of approx 1250 x 1720 pixels. In this case the Academy image would have to be resized down. The thing is Academy format movies are 50 years old or more, and film resolution gets halved every 60 years on average, and as the resize factor is quite small, you could argue the case that the modest 0.85x resize from 1250 x 1720 pixels to 1080 x 1485 pixels won't affect image quality too much.
So a BD 1080p 1080 x 1485 resize of that = 2k scan

If you scan the Pulp Fiction anamorphic 35mm negative at 2k, that would make the intended image have a size of approx 1440 x 1720. In this "worst" case, only the 1440 vertical pixels have to be resized down, as the horizontal 1720 pixels have to be upconverted to 1920 as was the case of the 1.85 negative.
So a BD 1080p 804 x 1920 resize of that = 56% of 2k scan

To get the 100% you'd have to have a new 2:1 anamorphic 2k Video format. Or jump directly into 2160p/4k

As always very informative. Thanks Dezi

I am so glad BLU-RAY came along. Before BLU-RAY most people were watching prerecorded 480I DVD movies. Some were watching 1080I D-VHS. I strongly believe that BLU-RAY will be around for a minimum of 10 years. BLU-RAY 1080P has over 2 million pixels which is ideal for current display technologies. If in 10 years a 4K movie delivery system is developed then I will be purchasing that format also. 10 years is a long time away and I plan on enjoying the current state of the art HDTV standard that is already in place. The first consumer 4K front projector when and if they arrive in about 10 years most likely will be between $100,000-$250,000. Then over time over several years prices will come down.

Just imaging having a 300 inch screen and being able to seat almost on top of the screen since the image is so clear that it looks almost like a window. 4K projection can offer over 8 millions pixels.

Academy 4K 3656 X 2664, ratio 1:37:1, 9,739,584 pixels
Digital Cinema 4K 4096 X 1714, ratio 2:39:1, pixels 7,020,544
3996 X 2160, ratio 1:85:1, pixels 8,631,360

Lower quality 2K projectors may show up in high end retail stores in 5 years. 2K can be made in either academy or cinema aspect ratios. Personal I am thinking about purchasing one of the new 30 inch LCD computer monitors for around $1500 that has over 4.1 Million pixels with a resolution of 2560 X 1600. Two years ago these 30 inch monitors use to cost $3,000. So $1500 is an excellent price. The monitors are known as WQXGA. There is a new technology that came out in 2005 called WHUXGA that has professional computer displays for military and medical use that has almost 37 million pixels with a resolution of 7680 X 4800. This type of resolution is awesome.

Almost:
HD = 1920 x 1080
2K = 2048 x 1107

Do you think 2k projectors are 1107p?

I have 4 more points like that too


Talking about Digital Cinema Projectors, they can have 1.26x anamorphic lenses for Scope ratio movies but see examples 1 and 4 of the minipost I made. Only in example 4, you would notice a slight improvement (14% increase in resolving power) if they "21:9" coded the anamorphic 2k scan for a Digital Cinema Projector with 1.26x lens



BD makes me happy feet

Personally i think Blu-Ray will be around for 10 years, but be improved on.

Like the 200GB disc will be standard in say 5 years, for 5 years.

Then i believe the new format (which i was hoping was gonna be the Flourescent Multilayer Disc but the production has been stopped) will be half the size of the then cinema-standard Ultra-HD which will equate to 3840 x 2160p x 30f w/11.1 audio.

That's my theory anyway, so 2017 i think Blu-Ray will be surpassed, but damn that's 10 years so go ahead and get yourself a BD player (7.1 audio enabled) & Full-HD TV (LCD, not Plasma) which will be in date til 2017.

From a simplisitic perspective, I think Blu-ray is quite future proof when you look at the fact that it has taken how long for the government, TV outlets, TV manufacturers, TV broadcasters, etc to go Hi-Def? And quite honestly, we're not even there yet. So, I would say we'll be in the High Definition era for a good 15-20 years and Blu-ray will be there in the forefront. So, in other words, I don't think you have anything to worry about as I don't see the government, TV outlets, TV manufacturers, TV broadcasters, etc making the jump to Ultra High definition or anything for quite some time. As one can recall, we've been in the Standard Definition era for a very, very long time--I'm of the opinion that you can expect more of the same with the High Defiinition era.

[Shadowself]

The current digital cinema standard encoporates two resolutions and two frame rates:

2K: 1080 x 2048; 24 & 48 fps
4K: 2160 x 4096; 24 fps


(((Personally, I would have preferred a slightly wider format to allow for digital cinemas to do the more panaramic imagery of the great epics, but I know I'm in the minority on this.)))

These are active pixels presented on screen. As most of you know, there are more pixels than this used for such things as dark current, Ne/deltaT and other considerations, but those don't show up on screen.

I can dig up the exact tables and references and dates of adoption if people really need them.

To the best of my knowledge there are no other resolution standards for digital cinema other than these.

Of course there are other projection systems that are non standard all the way up through E&S's Display Wall which is 4096 x 8192. And there are camera sensors which go all the way up through 9126 x 9126. But, as I said, they are NOT associated with any of the "standards".

[shock_terminal]

There are Manny different standards for Digital Projection at this time. My company produces content for Movie Theatres and we have differant sets for every theatre chain. This is part of the Problem, Most of them use JPEG2000 though.

Oh na, i meant cinemas only using Ultra-HD in abuot 10 years time.

I don't think the Ultra-HD will be the TV & broadcasting standard for about 25 years since HD isn't even standard yet as you say.

But i think the successor of 200GB Blu-Ray will be the halved Ultra-HD circa 2017.

As far as I know, there is only one "Digital Cinema" standard. There are not many "standards". There are many, many non standard systems out there as your experience only points out. Just because some chain of theatres wants something non standard does not make it a standard in and of itself.

Check out...

Digital Cinema System Specification
V1.0
July 20, 2005
Final Approval July 20, 2005
Digital Cinema Initiatives, LLC Member Representatives Committee

And the standard compression for it is JPEG2000. This allows them to do lossless compression for masters and lossy compression for various forms of distribution.

I dont care what experts have said, I am going to upgrade my dvd set into blue-ray set..remember that MD had been still around even CD rules the market..
