The Official 4K Ultra H D - Blu Ray Thread

Recommended Posts

As discussed in other threads, UHD on a small screen that is typical of a TV is rather pointless, unless of course you use binoculars and move your head a lot.

HDR may be to some advantage but it almost seems, at least to me, that the gamma is being manipulated somewhat by manufacturers to enhance contrast. I just wonder how linear that HDR grey scale really is ?

Owen is into this stuff more than most, maybe he is clued up enough on HDR to give it a thumbs up.

Excellent... good film to start the new format with. :)

It's not made clear though if these new titles are being released with a HDR as well as being in UHD/4K...

JSmith :ninja:

It is my understanding that all disks released under the UHD banner must have a form of HDR embedded.

Currently HDR10 and Dolby Vision are the two options, with each being mutually exclusive. I don't know enough at this stage to say which is better, but it looks like most disks will be HDR10, some may have both, and a smaller percentage with Dolby Vision alone.

From the information coming out of Germany( Ekki at cine4home) with the testing of the new JVC X5000/7000/9000 projectors it looks like HDR and the new improved DCI-P3 colour gamut included in the UHD standard are "very worthwhile" improvements over Bluray. Certainly much more than the improvement provided by the increase in resolution to 4k.

Suppose for those with the UHD TV might as well see what it really can do with some proper material.

I reckon the clincher might just be what pricing is when they hit the streets.

$45-$50 ? maybe more

Here we go again, the bleeding edge of Sony technology strikes again. :D

It all seems rather fuzzy to me but haven't we been duped by them before into thinking ..... this is the promise of video heaven about to be fulfilled ? :unsure:

Enter the world of firmware updates and disc compatibility problems at your peril, it may be better this time round, one can only hope. :D

perhaps Toshiba might develop their own 4K format

is there anything stopping another high resolution format ?

i mean as i understand it, its a blu ray format with a higher resolution, there is nothing stopping another company offering the same resolution in their own format, SONY cant hold a copyright or a patent on resolutions

perhaps if they overpriced and gouged (depending on its take up and popularity) another company might see an opportunity to be competitive and we might be lucky and see another format war on these here hallowed halls once again LOL

I think Toshiba have lost face from the previous format wars when one considers they had a saleable product but had failed to market it properly.

Likewise, unless Sony markets 4K properly it too will fail.

A higher resolution than 1080p won't convince people to spend on a similar sized screen nor will a brighter screen or even HDR.

Consumers have already bought into home theatre with 1080p Blu-ray and they are not likely to throw all that gear out to replace it with expensive upgrades that gives them marginal improvements.

4K requires a very big screen to justify its implementation, that means in a practical sense the use of a suitable projector in a dedicated room. In a great many households that is not going to happen.

4K is really pushing it up hill even more so than Blu-ray did in getting itself accepted in the marketplace.

Yes Dave ;posted this awhile ago ;;HDR10 is the mandatory spec for uhd bd [and is handled by all the new jvc's - sweet ] Dolby vision seems to be the best of the non mandatory ones ;phillips one not as good ..samsungs tv only proprietary one not as good either :question:

be some benefit from 4k, but for most its going to be marginal as we dont have imax setups ! to appreciate the better than imax res the format delivers. recent reviews coming are showing good benefit with HDR and wider gamut which regardless of 4k hopefully there for all to enjoy :)

Shazam, out-scooped again. :D

It does seem that UHD has peaked a lot of interest. I know that with my recent obsession to learn about the new JVC's there has been a lot to bone up on.

I am also a little concerned that if I end up with an X7000, then jump on to an Oppo 4k player when it's released, that with my old AVR, I'm going to have to overhaul the entire chain and upgrade that too.

It's a lot of investment considering we'll probably not see a massive UHD catalogue for quite a while. Especially 4k DI UHD, not just upconverted 2k scans.

Ah the price of the bleeding edge. Just don't tell the wife. :zorro:
