2k/4k - Blu-ray Forum

I expect you all get tired of me talking about restorations; for that, I apologize. All I have to ask any of you is this: Who is good at telling the difference between a 2K and 4K restoration which can be the source of a 1080p standard Blu-ray?

If anyone is an expert at this sort of thing, please let me know. Thank you.

Why?

I just don't want to make a mistake of purchasing one that isn't a 2K or 4K restoration, and if I do own one of the films that is not a restoration, I'll wait till a new restoration is announced (for example, I steered clear of buying the MGM Blu-ray of PLATOON, which is one of the films, and now it was recently announced that a 4K remaster of the film is coming to Blu-ray).

I know it sounds crazy, but if you were a classic movie lover like me, you would probably want to know what kind of restoration was given to the film so that you know you have the best looking version of said film.

I don't any of you to think I'm crazy for asking for help. I just a classic movie lover trying to get the best versions of these films.

heading into a deep dark pit with this. there will be "better" versions coming out for any number of films over time. ok you get a 2K restoration now but uh ooh... a 4K one comes out down the road. 4K restoration but maybe the encode isn't quite right.... the list goes on. you will make yourself nuts with this. just find copies that look good to you and you'll be fine.

professorwho · 07-24-2018, 09:01 PM

If it's a good restoration, you shouldn't be able to tell the difference. Resolution doesn't really matter as long as it is a good source and well encoded Bu-ray.

Then I’d say stick to the versions you already have, Blu ray is about as good as you can get, that’s just my honest opinion.

Except for 4K which features HDR and WCG that spanks Blu-ray?

Dailyan · 07-24-2018, 10:18 PM

It could be scanned at 1K for all I care. As long as it looks good, that's all I care about. A 4K scan doesn't equal automatic quality; the WORK that's put into such as cleanup, color correction etc. There's plenty of great Blu Rays that only "scanned at high definition" that weren't scanned at 4K or even 2K; MGM's release of Blue Velvet is a great example.

Bueller · 07-24-2018, 10:33 PM

We won't think you're crazy, it's just a little peculiar to limit yourself to a certain type of transfer for films in a certain film organization's list of American films. The majority here wouldn't consider purchasing an existing Blu-ray with no new release announced a mistake, as you do. There is a difference between best version available, and best version possible. And those both depend on the individual.

For example, Bonnie and Clyde has a 4K restoration but it's from 10 years ago on a VC-1 disc. Still the best version to own. And what about a case like Amadeus? Besides being removed from the AFI 100, it's also a VC-1 disc, but its theatrical cut is not included. Then of course there's all the classic films not on the list.

Not to mention all the DNR and smearing. It appeared to have a good source, but the compressionist did a terrible job.

CinemaScope · 07-26-2018, 05:23 PM

Well there's some posters here that, if it isn't 4K they just won't buy it (they say). I buy the best looking versions of the films I love (some classics, some guilty pleasures), & if a better version comes along I might upgrade, after all, Blu-rays don't cost a fortune (I might wait 'till the price nudges down). I do think that * new 4K restoration * is a bit of a selling tool.

Dragun · 07-26-2018, 06:03 PM

Blu-Ray is lower quality than 2K, so a Blu-Ray from a 2K restoration won't look any worse than the same film with a 4K restoration, all other factors being equal.

While scanning/restoring at 2K and 4K and then downscaling to 1080 retains more detail than scanning straight to 1080, I think a lot of the benefits of 2K and 4K masters come from the virtue of them being newer than the direct-to-1080 masters, with improved techniques and equipment being used to create them, and their resulting Blu-Rays.

oddbox83 · 07-27-2018, 11:42 AM

I find a 2K scan (as opposed to telecine) just as good as 4K one restoration being equal otherwise when the end result is a 1080p BD.

As 4K becomes the norm though, 4K scanning does future proof the restorations. I just hope they are archived as P3 colourspace masters as well for HDR extractions in future.
