There are no 4k discs at the moment. When they come they will probably need new players.

Blu-ray is approximately 2k. The 'Mastered in 4k' discs are a bit of a gimmick, that means the transfer was created/mastered in 4k resolution but then downsampled to blu ray ~2k resolution. But what is on disc is not genuine 4k because there are no 4k discs at the moment.

Hope This helps:



To me, this is technically a new format as all the current hardware will not support 4K. You will need a (To be Fully 4K compatible):

- Ultra HD (4K) TV or Projector
- 4K Receiver
- 4K Player (still not available, as there are no 4K discs available as yet)

Normal blu ray discs are 1920 x 1080, or 1080p. Just like Blu Ray (1080p) is an enhancement to DVD (720p), so too will 4K be an enhancement to Blu ray. Hope that makes sense

Isnt DVD only 480p i.e. 480X720

Yes it's 720x480 ,it will be stretched horizontally to 853x480 during playback.

i mean just forget about 4k
the sequence of our upgrade format of watching movies is
VHS
VCD
DVD
HD DVD
Bluray
and now 4k
or their in between blyray and 4 k

^^ When a disc says mastered in 4K, it just means that the actual film was scanned in at '4K' i.e. the actual film being scanned in digitally.

When the blu ray is authored, that same 4K transfer is downscaled to 1080P.

I have watched three movies that have had this:
- Elysium
- The Innocents (1961)
- After Earth

While i can say that i haven't really seen a difference with Elysium and After Earth (As compared to other normally authored BD discs), The Innocents (1961) is considerably by far an excellent transfer (which i am sure benefited from the actual 4K scan).

Any current Blu-Ray movie you see with the 4K banner (especially the Sony ones) will be mastered in 4K, but since there are no 4K discs, they're going to output in 2K (1080p). It means that the original source material is actually bigger resolution than what the disc itself has. When you take a big ultra-high-def picture and shrink it down to 2K, it's going to naturally look sharper and cleaner than most other movies that aren't remastered. In our current cycle of movie releases and re-releases, it's like the equivalent to the Superbit DVDs, which looked a little better than others because of their mastering.

I'm not sure how the Spider-Man movies compare between the older Blu-Ray releases and the new 4K release, but I have upgraded my copies of RoboCop, TGTBATU, and Fargo to the 4K remasters. They all show improvement over older releases - the original releases may have been taken from outdated DVD masters anyway - but RoboCop is especially striking. I was also impressed by the 4K release of Rocky (never even saw the original Blu-Ray release). There are also numerous Criterion movies being released in 4K (such as Breaking the Waves), and some select movies (like Blade Runner, Alien, Baraka) have been mastered at 4K, and possibly 8K. Plenty of new movies, like Elysium, naturally come from 4K masters or higher. They all have perfect quality...on a 2K Blu-Ray.

4K Blu-Rays will come out next year, apparently. I have no idea if the difference between regular BDs and 4K BDs will be that significant, but from what I hear, it'll be super-sharp, super-clean, and extremely vivid in color. But as far as comparing 4K-mastered BDs to other normal BDs, it boils down to how better of a transfer you're getting (and it usually is an improvement).

Consumers who've bought copies of the same movie in VHS, DVD, and Blu-ray aren't necessarily going to buy another version in Blu-ray 4K, and movie studios aren't necessarily going to trouble of remastering existing movies to take full advantage of the new format. But for new movies, already often produced in 4K versions, the decision to support the format is a lot easier.

Spiderman 1 and 2 look noticeably better but not as much as Robocop, Fargo or Ghostbusters, but those last 3 had problematic older scans the first time around.

Format changes that offer better quality are often a pain for consumers especially those who pick the wrong one, as was the case when the Betamax videotape format famously lost out to VHS, or when HD DVD lost out to Blu-ray. Consumers don't have to worry so much about formats with streaming media like Netflix,Roku or You tube etc.

True. But there's no concept of ownership through streaming

Yeah i agree,But the ultimate beneficiaries of technology evolution are consumers..

Actually, that is NOT true. You can 'own' Digital copies that you can stream via services such as Vudu & Flixster. I personally own several hundred movie which I can stream on different devices anywhere in the world.

That is not correct specifically for India.
You cannot open netflix/flixter/Vudu account from India without using proxy.
And officially those services are not available for India. Same goes for codes bundled with blu-ray package imported from US/UK.

Yes, if you have valid US/UK netflix/flixster/vudu account, you can stream your content anywhere in the world.

[nrD]

The thing is: you own a copy of those movies as long as vudu has servers and remains in operation. Or really, what if they delete a film you own from their servers for some reason or another?

You still have to stream the film, so all you really own is an access code to the file on vudu's (or other streaming service's) servers. You can't play that film from your own hard drive or your phone/tablet/media-device's local storage. That means if I'm on the road or in the plane, I basically don't have access to things I own to which I would have access if I brought a blu-ray with me or had downloaded a digital copy.
