4K Movies Releases

Well, ‘stand out’ is a relative term based upon one’s priorities, etc. I think even 2K makes a significant difference over HD if you have a good enough source and you sit close enough to the monitor….no matter what its size.

It all depends on how important image quality is to the respective viewer. I think that if Apple enables Quicktime decoding of 2048 files on their iPad Retina, DPs and Directors will then be able to view dailies which are of higher quality (easily appreciable higher quality) than 2K DCPs…and actually be grateful of having the ability to do so.

Even if there's a stark PQ difference, it's a good opportunity for more features. Similar to have Blu-ray adds functionality and usability to discs (chapter select while playing feature, etc). Of course early adoption may or may not be desirable for those reasons, but once the format is established more than possible.

One thing immediately desirable would be to have dual full 1080p for 3D.

Agree with Penton here. Sap, frankly I thought your impressions were spot on with my expectations. Thanks for posting.

Thank you. It was fair. I don't understand STD's comment.

I'll add that i was standing a little to the side (and about 4' to 5' back) watching the TV. The couches they had were all used up by people. I didn't get to actually sit down and watch from a seating position with the TV directly in front of me. Don't know if that even matters. Either way, i saw the resolution increase. But i plan to go to another store to see if i can watch movies on it and be in a better position.

Also, the people that were in the room really liked what they saw. All eyes were agaze on the screen. Some pointing towards the TV noticing the extra detail. That surprised me.

So much for the average joe not caring about 4K.

saprano, thanks for posting your views on what you saw with Sony's 4K HDTV. But like you stated earlier and that was your Kuro was good enough for now and so is my HX750.....for now and for the foreseeable future.

Thanks. I'll look into it.

If the entire paper is too technical for you, then just skip down to the last page and read the paragraph entitled “Potential Applications” or maybe just read this more layman-friendly piece –

Penton, what are your thoughts on rec 2020? Will 4K use this for the new BD spec and broadcast?

As for compression. I know it's been said a 4K film can be compressed on a BD50, but i hope we use at least a 100 gigabyte disc.

I agree. If you're building a new player for 4k BD's, why not add the 100GB capability as well?

Also, thanks for your review of the 4k TV. I hope to see one soon. Maybe there will be a demo model at the Mall of America some day?

You reeeally want 10-bit with your 4K UHD, don’t you.

No kidding. I couldn’t agree more.

P.S.
b.t.w., you can thank the companies in the consortium 4EVER …http://broadcastengineering.com/news...ncoding-system
for championing the inclusion of 10-bit in the HEVC spec.

People sometimes take the easiest path…or that of least resistance. It seems fighting mediocrity is a constant theme in business.

Nice. Good news. I don't just want more pixels while everything else is the same.

That's true. I don't think that way at all but I forget that many do. That's why we have MP3 as the dominant format for music and the rise of streaming VOD over Blu-ray.

If they are going to use a 50gb disc, 4K bluray is pointless! You are going to have to buy a new player anyway and for 4x the resolution the standards need to be raised beyond those of bluray. Warner wanted a 9gb dvd using VC-1 for HD. Stupid idea just like using 50gb discs for 4K. Toshiba and HDDVD came up with the same argument before it even starts by using advanced codecs at low bitrates being VC-1 at 10 mbps. I don't care how efficient the new codecs are higher gb discs are needed end of story. This is a niche product in the first place. Call it the laserdisc of the 21st century.

Think one could get away with it using two discs and new compression...

[vargo]

For a given quality, the required bitrate does not scale linearly with increasing resolution. 4x the resolution does not require 4x the bitrate.

And that is within the same generation of codec. Obviously moving to a new codec we get even better efficiency.

So 4k on a disc does not require hundreds of gigabytes. I expect BDXL to be the format of choice given that it is already developed and there is only very minor technical differences. Laser wavelength, pit size etc are the same.

That gives you the option to use 100GB and 128GB discs but of course you also have the option to use regular BD50s if the studio want and I would expect plenty of 4k movies to continue to use BD50s, particularly short ones or ones without many extras on the disc.

but there are already some of the longer films like Cleopatra, the three extended LOTR films Ben Hur and 10 commandments that use two disks for 1080p. It is not a big issue when it is a 4h film to get up and change disk, but do you really want to have to do that every 3/4 of an hour or an hour?

lol , I love that kid in the YouTube video….”How much will it be on black Friday?”

You know that 17k price (since it includes a stand that the TV screws into) is really not bad for bleeding-edge consumer technology in view of the fact that for the historical retailing record, the Sony Qualia 006 (which was considered to be the primo LARGE (70”) HD tv for its time when it debuted in Dec. 04/Jan. 05 retailed (and sold in its SonyStyle stores) for $13,000, plus, you needed a solid stand for it because the behemoth (about 275lb.) had no legs.

The Sony stand sold for $1,500., ergo…. a grand total of $14,500 for 70" of electronics that made 1080i into 1080p (the full HD of today).
