The filesize of 40GB is very low for a DCP, your standard 90 minute film is typically over 100GB. I recall Hateful Eight being over 200GB. If they released the actual DCP .mxf files it would be proof that the DCP was truly cracked.

As far as I know, MXF basically contains JPEG pictures and because of that, it can't use motion prediction algorithms used in modern video codes, so the size of 40 GB for a 4K video in H.264 format is possible. But I agree that it's better to see the original decrypted container.

Not really related but I didn't know about the integral cut of Kill Bill (it's possible to find it online). Any other gems like this? Maybe there's websites about this.

Apparently there is ONE theater in the world (in California of course!) that shows it and it's REALLY GOOD. EDIT: The one floating around the internet seems to be a fan cut. I'm curious how it holds up to the actual thing. That's what I heard. Also the the Roadshow cut of Hateful Eight. That was shown in more places. I could have seen it, but they asked for an arm and a leg, and I need those!

I saw the Roadshow cut at our local art house. It was beautiful. IIRC it was definitely not even 2x the cost of a regular ticket and it came with a commemorative booklet.

Worth noting is that YouTube was (and is) piracy in many cases

yup, there are a lot of re-uploaded videos and also command-line tools for downloading youtube videos

The former _may_ classify as copyright infringement. The latter definitely does not.

The "economics" here are interesting. One of the sources attributes the piracy to a "market failure". This is not accurate. As price falls to zero and supply is infinite (piracy) there is nothing to restrain demand. Sure I want all those Tarantino special cuts if they don't cost me anything. Got Tarkovsky in 4K? I'll take that too. Pirates try to justify their thefts in economic terms but at the end of the day they a…

If it's not "market failure", what do you call it when you either can't buy it at all, or it's made extremely difficult to do so?

It is a market failure. There exists a product, which is easily reproduced and simple to transport. These exists people who wish to purchase the product, and pay a fair price to do so - but cannot.

It is the classic example of market failure.

It violates YouTube's terms of service and hurts the artists.

To clarify for all the other non HD-video nerds, this seems to be regarding DCP: https://en.wikipedia.org/wiki/Digital_Cinema_Package not HDCP: https://en.wikipedia.org/wiki/High-bandwidth_Digital_Content... (which is already broken, and was itself the industry response to the breaking of DVD CSS: https://en.wikipedia.org/wiki/Content_Scramble_System ).

I find it amusing that after all these decades people are still willing to claim some sort of moral high ground in defense of their desire for entertainment.

After all these centuries, people are still willing to claim some sort of moral high ground in killing other people for their beliefs. And downloading a file is amusing?

youtube-dl has actually been really useful for backing up my own channel. Simply passing it a channel url and it will download everything in the best quality available.

When you say "projector," do you mean a projector like in a movie theater (shooting rays of light out at a screen, etc.) or something else?

Yes, there is custom hw in /retrofitted to cinema projectors. Can double the cost of the projector.

Wow, didn't know that. That's some serious next-level stuff.

The use of DCP seems to be limited to very high resolution releases. The DCP is just a digital print (what movie theaters play for digital releases instead of the reels of film that go with analog releases). It's not really about resolution per se, it's just a term for the whole package that the theater gets.

To add to this - a typical cinema release is a pretty big file - frame-by-frame encoded as jpg2000 in 4k. Often shipped on hard drives, or downloaded via dedicated fiber lines. They key material is distributed separately, and allows for fine-grained control of play back (eg time of day - to the point that if a screening is sufficiently delayed, it may sometimes have to be cancelled if a new key can't be acquired in t…

This is not a show stopper. All you need is one unlocked copy to drop in the open, and then everyone can work on it, and get it packed up in a more reasonable format.

  This all works due to proprietary 
  hardware - the modifications to the 
  4k cinema projectors that enable 
  decryption almost at the lens/imaging 
  chip can cost as much as the projector 
  itself, doubling the price of the 
  projector (last I heard from around 
  15k to 30k USD).
So, yeah, that's great, but the only level of piracy that could deter is the pixel-perfect variety. A motivated individual with a comparable budget could probably optically extract a high quality duplicate with an expensive digital video camera (and perhaps even a beam splitter), and pull signal from the speaker transducers with professional audio recording equipment.

There'd be no real need to tamper with proprietary hardware or intrude on the chasis of the projector. With reasonable equipment, it's likely that a person could reproduce a re-recording of a movie that is very-nearly indistinguishable from the factory source, perhaps except for negligible artifacts that might irritate only the holiest of true believers.

> probably the more likely scenario is that some insider leak some of the distributors private keys which would allow certain releases to be cracked - but would likely also trigger key roll over.

It could also be the case that someone leaked the plaintext symmetric key(s) for this specific movie's DCP. If someone gained access to private/secret keys on a compromised DCP player somewhere, it'd be smarter to leak symmetric keys for individual movies to avoid detection.
