There's a guy on twitter who has posted a few "remuxes" of films that appear to be ENORMOUS files (>1Terrabytes, etc.) in formats I'm not familiar with:
He's been asked about what exactly these formats are, his process, what the source material is, but none of his answers make sense. There's no way he can genuinely get files this large from even a UHD (<100 G) and I know he's not scanning film elements, so I wonder what the hell is going on. He does post scores of other legitimate rips and scans in formats and sizes that makes mathematical sense.
I feel like that checks out for ProRes encodes, based on my own projects I've exported in that format — especially in such a wide color space (4444). Nonetheless, seems excessive and frankly ridiculous, especially given the insane price of physical storage these days.
Yeah, those sizes aren't surprising for ProRes encodes of a three-hour movie. ProRes masters do leak, but based on the "4K DCP" labels, I can only guess that this person is somehow getting their hands on unencrypted DCPs, then doing ProRes encodes for obsessives who will happily take bloated file sizes (the 4444 encode is probably twice as big as the DCP itself) if it gets them closer to the holy grail of perceived losslessness. But since there's software out there that could directly play back the raw DCP on a regular home computer, I'm not sure why they don't leak that.
So semi-legit technology, then? Just seems like extravagant up-rezzing, which I thought was frowned upon as essentially "fake" resolution.
Also not sure I understand what "ProRes" is? I know DCP which does seem to be his source. If that's good enough to show in the cinema, why up-rez it for home viewing?
I've been seeing online that some people are getting 4K discs that aren't loading properly into their player.
I couldn't get 2001 to load on my Panasonic 820.
Nothing happens when I put the disc in.
I've come across a problem with the Barry Lyndon 4K UHD disc. At Chapter 16, the image freezes after Captain Potsdorff tells Barry that he'll have a signed certificate. It eventually jumps ahead to the shot of Barry entering the Chevalier's chambers.
I noticed it on my old Sony player, and just confirmed it on my Panasonic. It never happens in quite the same way twice, which makes me thing it might be some issue with the transition between layers, but that's just a guess.
I've had layer change freezing on Full Metal Jacket and Lolita. A Clockwork Orange doesn't even load on my Sony. I watched the blu ray instead, which still looks great, but I'm a little upset about the 4K disc. I'm asking for a replacement.

Why does criterion have so many disc problems?
I buy a LOT of movies, but Criterion is by far the worst for problems with their discs.
Fully agree, I've had zero problems with a single Arrow disc, even with my last funky player that had problems with every other 4K. My new player has only had problems with (brand-new) Criterion 4Ks. What makes the situation even more frustrating is that their customer service is still silent a week after sending emails asking for a corrected disc (Maybe they're overwhelmed because so many people are reporting problems with their discs!)
What's odd is I had no problems with any discs (though haven't watched Eyes Wide Shut yet), not even taking screen captures, and I was expecting at least one to give me difficulty (I had 2 give me issues in the Anderson set). So it just shows how random it is with them, too.
For what it's worth: As a Panasonic UB820 owner, I had so many issues with Criterion (and Arrow) 4ks when they first started releasing them. I got to my fifth replacement before I decided to take a look at my setup and, just by chance, chose to replace my HDMI cables. Suddenly, everything started working without issue. This is all to say, sometimes a bad cable can cause bottlenecks and it's a fairly inexpensive fix/troubleshoot.
I switched out HMDI cables too, which helped at times in the past but hasn't lately. I also have two players now, so I'm able to test discs on both and the same place will skip on a Criterion disc every time
Do you guys turn the player on by opening the tray and then closing it with the disc in? I've found the player is more likely to encounter problems this way. Now I always turn the player on with the power button and wait for it to settle on the main menu, and only then open the tray to load a disc. Might just be my player of course...

I had 2 discs that needed replacing from the Anderson set.
I paid $20 to get tennenbaums, and then had problems with Fox. Now I have to pay a seperate $20 to get a new Fox, so i am waiting until I watch everything in my Kubrick set before I send them that money, just in case.
Interesting on what is being said about powering the panasonic on by opening the player.
Yes, this is also how I generally power it on.
I'll try your method.
Request for the moderators: Could we move the discussions of the player issues to “Technical Issues and Questions”? Though at this point, it seems the Panasonic UB820 may even merit its own thread.
