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…

The price isn't "zero" - it's a low-likelihood/high-impact risk of being sued for copyright infringement/having your internet shut off for "strikes"/moral guilt/etc.

This. Also inconvenience, time spent, process complexity etc.

In fact piracy can cost so much, people pay actual money to avoid it. I think that is why Spotify et al. are so popular among prior pirates.

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.

I'm assuming they reencoded it to something more efficient than mjpeg2000 (no idea what the "standard" pirate codec for 4k is).

EDIT: According to another comment it's H264.

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...

I don't know DCP, but from reading wikipedia it's something different than HDCP:

HDCP is encryption during transmission (like SSL), e.g. encryption while transferring the movie data through the HDMI cable. It is not used for encrypting data on a storage medium (like CSS, and apparently also DCP are).

Okay, just think about this for a minute.

Who would EVER care about a cipher key, when YOU STILL NEED TO EXPOSE THE RAW PIXEL RASTER, AND AUDIO CHANNELS TO THE END USER, IN ORDER FOR ANYTHING TO BE VALUABLE AT ALL?

Users will always eventually get the whole thing in the clear, in straight-up plain text somehow, eventually anyway. And all anyone needs is a buffer big enough to capture it, and it's trivial to assemble one.

You need to be able to watch a movie with the naked eye, and hear the sound with your ears. That's how movies work.

It's trivial to capture the raw data, and people have been living with NTSC quality picture and sound for decades.

This is not about perfectly matching the SHA256 hashes of the original MPEG artifacts. People just want a copy, and it's easy to skim one, somehow, one way (cracking) or another (brute force direct copies of the image frames and pulse code samples, at the signal source).

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!

Earlier quoted context omitted.

They wouldn't send a DCP stream for transcoding. DCP stream can only be decoded by the media block inside the projector and the output physically goes to the projector chip. The system has safe guards against physical intrusion. If you open the projector, it wipes all the keys. The level of paranoia in that thing is insane. They keys only get programmed by the studios at manufacture time, and there is no servicing of…

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.

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.

Some people believe that copyright infringement is a morally acceptable response to copyright terms changing from limited to effectively infinite duration.

Yes, of course, but it's a lossy copy since you're de-compressing and then re-compressing the content. (At 4k is that as important? I dunno, I'm not a movie fanatic.)
