Pirates Plunder 4K Hateful Eight, but Did They Crack DCP?

> “I strongly condemn piracy and find it generally damaging, but it is a symptom, not the source, of market failure,” he told TF.
That's it right there. Music piracy took a long time to sort out because it was inaccessible. Now through Spotify/Apple Music/Youtube I struggle to find anyone who pirates music in my peers (it was prolific). It's not perfect yet and I think there's still some change to come but it's certainly ahead of the film industry.
1. Most people have no desire to go to a theater anymore, so making people wait months to see a new film means they're going to try to find a way to see it sooner. If they released streaming alongside movie theater releases I would imagine you'd knock out 90%+ of the piracy out there.
2. People like me who are on extremely limited bandwidth connections can't watch anything in high fidelity via something like Netflix. Need a way to buffer the whole movie locally ahead of time. Let me queue it up the night before so I can watch it when I get home from work and you'll have my dollars.
Aside: Saw Pets with my kids this week; Large Soda is now more than a Bud Light at a Football game ($8). Consider me among those who would gladly stop going to the theater.
People are made to throw food and beverages in the trash, if they haven't been purchased at the theater's concession stands.
When the ushers take your tickets, they make you throw away anything that's obviously not sold in the theater, thus monopolizing local refreshments.
Box office sales have generally increased over the past 20+ years. Possibly people in your peer group may not, but this does not seem correct. http://www.boxofficemojo.com/yearly/ http://www.the-numbers.com/market/
In 2016 slightly less than 0.13 tickets were sold per person.
This highlights 3 things.
- In the grand scheme of things most people in the world don't go to movie theaters and never have.
- Less do than ever before both in absolute terms and proportionally.
It seems unlikely that steadily raising the cost of tickets and food is going to be a sustainable way to avoid falling revenue in the future.
The smart money ought to be giving people the movie experience they want at home and giving people a higher quality experience out with a higher price tag.
The former will obliterate a lot of theaters and the latter is a smaller scale demand than the existing industry.
That's the problem that Sean Parker is hoping to address with his proposed streaming service[1]. At $50 a movie, that doesn't seem unreasonably priced. Until then, though, there's always the Prima Cinema option[2], but then you're looking at $500 a movie, plus $100k+ for the the initial setup, so it's not a great choice if you're impoverished.

The former _may_ classify as copyright infringement. The latter definitely does not.
Downloading that video (whether by watching it on Youtube or by using a tool to download the video to watch offline) is, if you don't have the permission of the rights holder another very clear copyright breach.
There's some narrow exceptions for free use, or public domain content.
I'm surprised you think it isn't. In what country would that be true?
Watching a video on Youtube is only lawful if the rights holder has given their permission. Here, the rights holder hasnt given their permission and isn't getting compensation, thus it's not lawful in Polish law.
It might be useful if you provided a cite the the Polish law that gives this exemption.
The person uploading the video is clearly breaching copyright, and if they monetise the video that becomes criminal in most of EU. But the person downloading the video is also breaching copyright, albeit not criminally.

Evidence required.
A Facebook group will find a popular video on Youtube, then either edit out all identifying information or just remake the video, then post it to their group to get the views and ad revenue.
EDIT: For fuck's sake, this is true, and follows from WIPO Copyright Treaty into the Copyright Directive for the EU and whatever the US equivalent is. Breaching copyright as part of trade turns it into a criminal offence, merely breaching copyright for personal use is a civil tort.
That's why in the various bit-torrent legal cases people who torrent are sued for loss by companies in courts, while people who run businesses running torrent sites are prosecuted by law enforcement.
If you're a content creator trying to build an audience, it definetly hurts when people already saw your content elsewhere.

So... why are we talking about re-uploading again as if downloading was the same thing?
If perfectly legal, permissible, expected and ethically justifiable behaviour hurts your bottom line, your business model is broken, not your customers.
, because?
Please note that I don't mind DRM when used in streaming but I find it onerous when I "purchased" something.
eBooks are problematic because finding DRM-free stores for current titles is near impossible and I hate that my notes and the book are tied to a B&N/Google/Amazon account unless I use tools to extract them (books + notes). I'm essentially paying near the same price as a used copy of the physical book, but I'm renting the book. If Amazon of Google ever give up their books service in a prolific blaze of fire, customers lose all those purchases.
I highly doubt Amazon would delete all the books off my Kindle if they were shutting down. I wouldn't be able to re-download them if I lose my device, but then again Barnes and Noble doesn't ship you a new book if you leave it on the bus.
As it stands now, sellers can sunset a DRM system with no consideration of its users.
Sure, services who uphold basic principles such as listening to a market demand and adjusting prices to it exist nowadays; yet the root of the problems; it being impossible to define a marginal price; still exists. Some of the monopolistic effects are not felt by the masses, yet they surely do exist. Think about market entry for example, virtually impossible. We have to raise the level of the debate i'm afraid....
Music piracy is still huge. Any top 40 album is going to have THOUSANDS of seeders, who knows how many people have downloaded from them.
> who knows how many people have downloaded from them
BT trackers do. And with enough seeds / pretend-seeds you can get a fairly precise numbers of downloaders.
There's still a number of countries where Spotify is not exactly cheap. Or where you can't get easy access to a permanent connection for streaming. But those places aren't huge record label customers either.
The top movies are getting ten of thousands of seeders. They get thousands in each of their localized version (French, German, Spanish...).
Go to one of the "current-best-streaming-site-of-the-moment.inwhatevercoutry" [1]
Some of the streaming sites publish the "views per video" (or downloads per video for DDL site). The top 10 videos are all in the hundreds of thousand of views.
The English streaming sites are in the millions of views per top video. They get more audience because of the language.
In comparison, it seems to me that music is not very popular for streaming/DDL/torrenting. If anything, it should concentrate all the views in a few places only because songs exist in a single version in a single language.

The use of DCP seems to be limited to very high resolution releases. HDCP is still what current era consumer hardware uses, and it's totally wide open.
As always with DRM, it's defective by design. https://en.wikipedia.org/wiki/Defective_by_Design
If you can view it, you can copy it... it's just a matter of time, motivation, and desired quality.
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.
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).
With a more sane key distribution (no master keys in equipment, like with dvds) - I don't believe DCP is likely to be cracked in the same sense CSS was: 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.
Also worth nothing that the DCP format is pretty nice, has optional encryption - and you can make your own. With the right contacts you can view your own footage on on a cinema screen :-)
See eg:
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.
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.
In a way it's shocking that huge cinema screens ONLY project 4k. When we had film instead of digital projectors, we actually had a much higher resolution on screen. It's a shame we replaced it with an inferior technology.
Similarly, a highly priced vinyl player might have slightly better sound quality than a cheap CD player.
But for most people, digital Cinema and CDs represent a vastly superior experience.
It's not because a technology is newer that it is necessarily better. CRT still holds some advantages over LCDs, Paper still holds advantages over e-ink, and so on. Of course Digital photography wins by a large amount for cost and convenience, but that's not the whole picture.
Anyways, most of old stock (print, negative, ip) have grain such that over cca. 2.5k won't yield anything better. However, kodak and fuji stock from mid to late eighties definitwly is worth capturing at higher detail. Highest-detailed stock from nineties we've measured to have spatial rwsolution of around 8.5k and that's about as high as you will get (rare) out of 35mm.
tl;dr; depends on the stock
edit: Here's previous mini discussion regarding telecines, if anyone's interested https://news.ycombinator.com/item?id=11377678
There are enough good 4k releases of classic movies to see this is not the case. You can compare the 4k and HD release (which is just under the resolution you provided).
I regularly scan Vision 3 film (movie stock) and Velvia 50 and Velvia 100 (E6). I scan it professionally at 10 Mpix, but when I have a good picture, I pay big bucks to have it drum scanned at 100 Mpix. Yes, it's not 100 Mpix, there's about 15-25 Mpix worth of detail there, but it's much, much more detail than the 10 Mpix scan.
I've seen both, digital is better.
Film has grain, which is a type of non-chroma signal-dependent noise that is not unpleasant like chromatic signal-independent sensor noise or shot noise you get digitally in photography (not in movies, they have good lighting there).
In fact, grain is actually useful, as it's aesthetically pleasing in small amounts, can increase apparent sharpness. In fact it's so useful digital creations fake back in post-production a small amount of grain.
> The resolution is not as high as you are imagining.
The resolution of 4k projection is not as high as you are imagining either. It's just 4096x2160 lines (often less, depending on aspect ratio) or 8.8 megapixels.
In the best circumstances you can get 25Mpix of useful data from a 35mm frame shot on low grain stocks like 5203. In the worst circumstances you get 10Mpix. This is 35mm, The Hateful Eight was shot on 65mm stock, which has a camera frame surface are of 3.44 times the camera surface of 35mm film.
Either way, the resolution of 4k digital cinema is fine, I miss more the old contrast and gamut.
And no, it's not aesthetically pleasing in any amount. Directors that add it back artificially should be criticized. It looks like there is a swarm of gnats flying across the screen, and unless there are a ton of bugs in the scene it doesn't belong.
> This is 35mm, The Hateful Eight was shot on 65mm stock, which has a camera frame surface are of 3.44 times the camera surface of 35mm film.
It won't stay that way by the time you watch it, it will have been copied multiple times, and it's on 35mm again. The effective resolution as seen in the actual theater does not beat 4k, and you have additional noise which lowers the resolution even more.
The main thing though is that noise is worse than lack of resolution. Depending on how far you are from the screen more resolution is meaningless - but noise (like film grain) is always a problem.
> I miss more the old contrast and gamut.
I suspect you are missing what never was. Digital is better on both.
No, it's not on 35mm again. I've watched the 70mm projection of The Hateful Eight. At no intermediary point the film was on 35mm.
The intermediate film stocks and the print stock are very special low-sensitivity stocks (Kodak 2383 has ISO 1.6, Kodak 5302 has ISO 6) that have no discernible grain whatsoever. You can't see the Kodak 2383 grain with a grain focuser. All the grain comes from the original negative. You do lose some spatial resolution with multiple copies, but you don't add grain. I'll note that modern print film like Kodak 2383 can resolve 550 lines per mm, and contact printing has a minimal loss of quality due to imperfect optics. Granted, a showprint will always be better than a release print, but the copying process is much better than you give it credit for.
> noise (like film grain) is always a problem
Not really, dithering is essential for all video processing. Your very clean image is actually full of noise. Without dithering, videos (and movies) would look bad.
> I suspect you are missing what never was. Digital is better on both.
Absolutely nonsense. Kodak 2383 has a D-Max or 4, giving a contrast of 10000:1. Kodak Vision Premier Color has a D-Max of 5.5 giving a contrast of about 310000:1. Yes, not a typo, one-third of a million to one. There is no other technology that can achieve these deep blacks. Digital projection doesn't come any close, the best projectors today, (the ones that you won't find in any run-of-the-mill theatre) can barely do 2000:1.
DCI-P3, the color space used in digital cinema was modeled after print stock gamut, but because of technological limitations, it's not identical. Cyans and yellow has a higher chroma on film. Green on film has a higher chroma at the expense of luminosity. Other colors are pretty much the same.
The only way for digital projection to have a higher gamut is to switch to laser projection AND to retire DCI-P3. You need a green laser to produce more saturated greens.
Digital cameras are capable of recording a larger gamut than film, but unfortunately there is no technology to display these colors outside laser projection, and you need to switch the whole movie industry to a new color space.
If you go down to the microscopic level film goes way beyond the resolution you can ever hope to achieve with the best digital cameras out there. It's just not something that is expressed in pixels.
> If you go down to the microscopic level film goes way beyond the resolution you can ever hope to achieve with the best digital cameras out there.
That simply isn't true. At the microscopic level film pixels look like "clouds" of colored ink. The pixels are not square, but they are there, and they are not the size of atoms, but much larger - you can see them in a typical microscope (I know, because I tried it).
Digital is cleaner not because of filters, but because the actual capturing technology produces a cleaner signal.
A couple of years ago there was still an argument, but these days the argument is over. Digital clearly won.
No, only color reversal film (slides) looks like clouds. Negative film, the one used in movies, looks like crystals (because they are crystals).
> actual capturing technology produces a cleaner signal
This is true, albeit for a film like Kodak 5203 or Kodak 5213, you'd have a hard time proving that this is true. These stocks are so smooth with good exposure and proper development (as it done when making movies) that you need a grain focuser to see the grain. Many blockbusters and big productions that you probably saw in a digital cinema were shot on this film, and you never knew.
> Digital clearly won
Digital is much cheaper, it's very good, and allows much easier intermediate processing (editing, vfx, color timing, etc). Of clourse it "won", although film is still widely used, and although archival copies are still done on film.
The fact that digital won doesn't mean that projection has better resolution (it's roughly the same for 35mm, but worse for larger formats) or better contrast (it's far, far worse for digital) or better colors (film has more saturated cyan and yellow, although this doesn't matter much). It sure has less flicker though.
There are still plenty of reasons why people shoot film, use a digital intermediate workflow, and print film today.
You are using survivor bias to prove your point. My point is that Digital is inferior in SOME aspects to Film - and it still stands. The fact that Digital won has nothing to do with the facts to be considered when doing a comparison.
DCP can be a pain in the ass for indie filmmakers, though. These days it's easy to generate a DCP from footage, but basically impossible to test it without actually putting it through a DCP projector in a cinema. This is crazy.
But it takes a lot of experience to imagine what a frame that looks great on a ~24 inch monitor will look like when projected in a theater.
I would strongly recommend that anyone dreaming to screen something in cinemas make a deal with their local cinema in order to do test screenings - to check picture and sound. Just like with anything else, there's no substitute for testing under "real" conditions.
Note that most(?) cinema setups will happily take some form of digital audio/video signal and run it through dolby surround and project it - so you don't have to start testing with a DCP file. But you certainly should test that in a cinema before distribution.
Also note that the "player" part of a fixed installation might have quirks/bugs that software that's more easily updated might work around (think mplayer vs a cheap old DVD player).
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.
What does that workflow look like?
Where can I buy one?
Last I heard, smallest 4k projectors start at $400k.
If you have the right friends, and hang out with the right group of people, you can get sometimes unencrypted material, just like in the old days you could get film reels. But a 35mm film projector was relatively affordable, this new digital stuff is still crazy expensive.
I'm curious what I should be keeping an eye out for, what sorts of people would be the most interesting to chase, etc, to maximize my chances of causing this opportunity to present itself at some point in the future. (I'm not particularly social right now.)
I'm not defending DRM, but it's important to know one's enemy.
It's frustrating wanting to give money for something, and not being able to.
This way he made a legal purchase and exchanged money, but still gets a DRM-free high quality copy to move around to his various devices.
If the focus is on quantity and diversity, I can understand just getting a decent-bitrate MKV or MP4 of just the film, but it might be worth it to see if there are Blu-Ray rips of the media in question "around" before just grabbing what's out there; at the very least, complete (and perhaps even decrypted, since that's finicky) rips have reasonable value on private trackers.
I'm guessing this sort of thing has probably already been taken into account.
For each movie, copies are released over time and a correlation can be looked at between quality of rip, distribution by file sharing, and box office receipts.
The "problem" is that it would obviously show that the impact of torrenting is much less than one lost sale per download. And reflect that even the downloads that are lost sales are offset to some degree by the people who download to sample and then buy when they otherwise wouldn't have, and the free promotion from the people who downloaded it talking about it with other people etc.
The result is that the likely "negative impact" would be small or could even be positive, which isn't the narrative Hollywood wants to spin. Because they actually want DRM for entirely different reasons than that, specifically because it allows them to control content delivery and thus prevent independent content from being displayed on equal footing with big studio content.
Yes and now, You cannot say that people who pirate games are necessarily going to buy the game if it were not "free". That's the argument used by the industry to justify DRM and it makes no sense whatsoever since the market would be like 100 times bigger if you calculate things this way. It would not.
This can't be true as written, as long as people expect it to show up there eventually. Every day it stays off piratebay is an extra day of revenue intermediate between full and "already out on piratebay" levels.
The DRM works because the value of these things appears to be greatly time-sensitive -- most of the cost is already getting-it-right-away, which DRM can protect, rather than the fundamental timeless value of the product, which DRM can't protect.
It depends on what the desired outcome of the DRM is. A prime example of effective DRM is Denuvo [0]. Loosely speaking, there are two main groups of people who pirate games - those who would buy it otherwise, and those who wouldn't. There's not much you can do about the latter group, so they're not really worth considering. The former group however are the potential lost sales. The sales for a AAA video game usually peak on release or very shortly after, and fall off a cliff very quickly., If your DRM system manages to keep a crack for your game from being leaked for the first few weeks of its life, you will capture many of the people who fall into the "might buy your game" category.
Also, I would be surprised their isn't a watermark in there that will point to the cinema who leaked the version.
And exactly the time and motivation needed is why DRM can work in the end. Modern DRM schemes like AACS employ methods to change keys for new works. So when crackers find a key that allows them to circumvent the DRM scheme they can't publish it or it would soon get useless and they would have to do the work to extract a key again. This is probably what we're seeing here.
This means that for consumers the DRM stays effective. They can't do copies of things they legally bought.

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).
In theory, if the picture is revealed on a display, upon which the full pixel raster can be distinguished for every frame (in real time or slower), an optical capture may be performed, which preserves the original fidelity of the image, and one need not recompress as lossy for peers who have the capacity to receive the full duplicate.
All images are eventually revealed optically somehow. Such images may be captured directly, and corrected and restored according to original quality, if you have good video equipment.
Only one good copy needs to make it into the open, and then the cat's out of the bag.
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).
In the end, copyright is based on laws created by governements as trade agreements, rarely involving the voting public when it's not a dictator or monarch making the rules. In effect copyright is a matter of law, not moral, and sometimed the law is not moral. In this case, I stay my judgement as it can only cloud the real issues.
Personally I think everybody who is not an adult, without a job or a home should by default be allowed free access to anything we call culture. Being part of society is - which everyone should be - is down to having a shared context. The so called entertainment is a major part of this, and without access to it you become an 'other', the outsider.
Moral or not.
So many movies are only available commercially in their objectively worst version (pan and scan, poor subtitles, no subtitles just dubbing, missing scenes, censored scenes, poor audio or poor picture), people who actually care for the film more than the copyright holders go out of their way to combine several awful versions into a version better than commercially available because they actually care about what they're distributing because it's for passion not profit..
And this is the framework the US is pushing the rest of the world to adopt.

So if the DCP was indeed cracked, it was either because they gained access to the FIPS module in a DCP playback server, or they gained access to the plaintext content keys where the KDMs are generated. If they have the server's private key, they will be able to decrypt every other film that they have a KDM for and we should expect to see more DCP releases.
If you have individually encrypted copies, it would be stupid to not also individually watermark them on the content level. With a bit of targeted key invalidation, this could well be contained to a one time breach.
If they released the actual DCP .mxf files it would be proof that the DCP was truly cracked.
EDIT: According to another comment it's H264.
Firstly DCPs are not wrappers that contain MXFs. From what I remember DCP predates MXF.
From memory (its been 8 years since I've actually dealt with creating them) They are effectively zip files that contain JPEG2000, lots of metadata and some sound tracks.
Crucially, the authoring and encryption are controlled by a central authority. Each projector needs to be registered with a KDM to make sure it can receive decryption keys. http://www.artsalliancemedia.com/software/screenwriter#featu... is one system for managing projectors.
Getting a distribution DCP is pretty hard, also Keys are short lived. But, someone people create non-encrypted DCPs for various purposes.
If its a MXF, then that suggests its either from a finishing house, or more likely a producer's laptop. (ie how wolverine got leaked, a pissed up producer leaving an unencrypted laptop on a plane. Even though their flight was pointless, as there are many remote viewing systems about. )
So my first guess is that they had the ability to snoop on multiple key exchange messages and some how used that knowledge to find a shortcut to solve AES based on the gleaned knowledge from all the gathered keys, or they broke into a projector and took its internal key.
And hence you have a safer product? The exact thing they are trying for?
The objective is to slow down pirate release. Seems to be working exactly as planned.
The movie files in this case are not meant for consumers. They're only decrypted on specialised equipment not accessible to the general public. If you manage to get your hands on a DCP file there's nothing you can do to decrypt it without access to the specific projector system it was intended for (unless someone screwed up somewhere of course)
Sure, they make it look all secure, pass it through all that crypto and stuff but ultimately it has to be passed to the projector chip in some form which is unencumbered to be turned into light. At which point it's fairly trivial to dump. Anti-tampers on the case are probably fairly limited.
If they have been any kind of smart when designing them, the decoded stream takes a limited, shielded, and highly tamper resistant path to the projector chip, and each and every critical component are paired with each other such that switching one of the out automatically destroy all keys.
What tech is used on UHD consumer Bluerays?
I bet there is not one legal service available online where you can view 4k media without streaming and without country specific restrictions.
DCP controls chip sales very tightly in the US, but I imagine it's a practical impossibility in Shenzhen.

You can buy these devices on eBay.
I'll admit that I sometimes watch a poor cam video before going to the cinema. It costs £10 a ticket plus food and fuel - about £15. Critiques often don't represent what I like in films, so I would just not go.
Pirated films probably encourages people to watch films. It can create a bigger hype around a film.
I think the war on piracy somewhat echoes the issues of the war on drugs.
Why might that be? Maybe the market is too small. But in that case, why would they care about piracy? Strange.
I went to it, and all the little touches (like the pamphlets) were really well done, and it was indeed a special, memorable experience.
It's like limited-edition figures or tins. Some people buy them because they're limited, and it's part of the selling point. The company can't later release it because it'd no longer fit the original sales spiel.
Studios rely on a lot of insecure distribution and storage mechanisms for the big DCP file and instead rely heavily on the secure key exchange.
If they have cracked DCP, somehow, then it is a major coup.
They keys only get programmed by the studios at manufacture time, and there is no servicing of the parts in the decode chain. The whole module has to be replaced.
I actually worked on a media block design about 10 years ago.
However I guess anyone who values something so much would also go to great lengths to protect it.
Still... wow. I mean, how much does it cost to design and implement that system alone? tens of millions of usd at least?
What if it has no power?
From what I recall, the security module has it's own battery backup, intrusion detection, etc. If the module detects tampering or it's battery goes flat, the keys are wiped.
There was some talk about that you can't keep "spare" security modules hanging around, they need to be installed in a projector periodically to recharge the onboard battery.
...due to its 40GB+ size.
and is visible in the screenshot: https://torrentfreak.com/images/hateful.pngStill, as other commenters note, these large disc sizes accommodate for high quality. If we have a 100GB disc format, and you want the 4K video to appear in the best possible quality, you will choose some encoding options that fill up most of that 100GB disc, minus whatever the special features and audio tracks cost. Most consumers won't care about the size: it's on a disc, they're not ripping it to a hard drive of their own.
A VCD release fits on a 700MB CD, why did we need a different disc format for DVD?
You can make video files come out any size you like - even 1 MB - if you're willing to make the tradeoffs (on both quality and time-to-encode dimensions). There's also a limited amount of hardware you can put into a set-top player while keeping a consumer-friendly price point.
Even just glancing around the more specific private piracy sites you can see far more love and care placed on releases than most commercial releases.
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!
At minimum wage I would have paid about a day's salary, and thus I "boycotted" it.
"483 scan lines make up the visible raster"
The 525 includes a lot of other stuff. Easy mistake because PAL shows 576 lines (out of 625), but only at 25 full frames / 50 interlaced half-frames per second as opposed to 30p/60i for NTSC. (PAL DVDs are also 576.)
While they're all constrained by the scanline in the vertical direction, the analog standards are resolution-limited in the horizontal raster by the bandwidth / frequency response of your signal chain; I've seen beta-derived analog NTSC that's gorgeous, far better than DVD. Especially on a really well-corrected CRT monitor (really!).
The decision to go to an even 480p for DVD probably derives from the 8x8 pixel blocks of the MPEG-2 compression. Having raster dimensions that are evenly divisible by 8 is a good thing for a lot of these block-based codecs; I believe MPEG-2 couldn't go below 8x8 (h.264 can accommodate smaller and non-square macroblocks, though).
That said, there's a nugget of truth in your comment. When we go to digital, we often get better average fidelity, but worse maximum fidelity. A beautiful analog system can be really great. Maybe in twenty years we'll have a hipster revival of 70mm film prints? It's the new vinyl...
(I'm being a little tongue-in-cheek; reports from Ang Lee's latest movie are that the digitally-captured 4096p120 stereo 3D is better than the real thing. I saw 30-year film industry veterans were walking out of a test screening shaking their heads in disbelief -- I couldn't get in because the line was around the hall.)
Pirates try to justify their thefts in economic terms but at the end of the day they are no different than someone taking socks from Walmart. They want goods or services that others have worked to produce without compensating them for their work.
Seriously, just own it dude. I stole this movie because I wanted it and I could. The Hateful Eight 4K is tearing down the academic pay wall to bring knowledge to the masses. It's a free movie and Cheetos.
I agree that people just want free stuff, but stealing a physical object deprives someone of that object.
Copying media is strictly a violation of a business model. There is minimal (if any) marginal cost to the owner. Better analogies include sneaking into a (not full) movie, hopping a turnstile, or not putting money into the meter (again, when other spaces are available).
Your literal minded response suggests that, a product with a low incremental cost is a valid measure of of the total cost of production, which it is not. The cost is writers, actors, foley artists, costumers, grips etc. All of whom lose money when someone decides it's okay to steal a copy. That is a thief who will never pay a legitimate fee for what they have taken.
No. We could take a snapshot of some artist's bank account, ask her not to make or receive any payments for a short periods of while. During that while, I run a loop that downloads or makes a few million copies of some song or movie or whatever. Then we peek at her account again and look, the number is exactly as before. And again we have peace of mind in knowing that merely shuffling bits and bytes around a hard drive or even across a network link has no bearing on what happens in someone else's bank account.
That's the thing with physical goods. Once you receive money and give your customer the thing, if it gets stolen it's the customer's problem.
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.
I pay for Spotify for convenience and functionality (syncing between devices, perfect tagging/catalog/artwork), not because of any potential risks surrounding piracy.
It is the classic example of market failure.
There's zero competition in the distribution/publishing side of things for a movie - i.e a retailer can't choose to buy Star Wars from anyone other than Disney, or the Bourne films from anyone other than Universal.
They have no potential incentive to be more responsive to market demands. Market Segmentation is a great way to ensure the highest revenue per sale, so they sell it into each market for as much as the market will support.
Then there's exclusivity arrangements in the online side of things - so I can't get (say) Game of Thrones on Netflix.
In Australia I have to subscribe to Foxtel and pay a fortune for premium channels, and if I want to watch it online, well, I can get a pretty crummy quality stream in some other painful to use app. Or I can wait 12 months and buy it on DVD/Bluray, which are still only 1080p.
The distributors/publishers are free to fix that, today, if they wanted to - but they don't.
So griping about "regulations, laws and cronyism" doesn't ring true. (Well, maybe the last)
