There's a difference though. DRM music files are sold directly to consumers. These consumers have to be able to decrypt the files on their own computers / devices which makes DRM useless. 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 w…

Yeah, but let's be honest, if I had a job as a manager at a theater and a moderate amount of reverse engineering skill or a small team of friends with those, well, time, access and tools combine quite well... 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 i…

You'd be taking a big risk once a watermarked release gets you. Perhaps you could blame it on a rogue employee and get away with it. Still, big risk.

> 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.

Uploading a video to Youtube if you don't have permission of the rights holders is a very clear breach of copyright. 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 th…

E.g. in Poland. Don't be surprised, because it's not an absolute truth that you breach copyright watching something published.

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 ). The use of DCP seems to be limited to very high resolution relea…

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.

I find it amusing that after all these decades people are still willing to have cultural artefacts being distributed at the whim of corporations rather than passionate archivists who actually care for the work.

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..

Regarding HDCP, while 1.x is currently wide open, I'm not aware of any "crack" of HDCP 2.2, the currently required version for 4k content. There might have been keys leaked, but key extraction is only getting harder, with devices embedding keys deeper into the chipsets, with software/hardware video paths inaccessible from traditional OSes, etc. Also, I would be surprised their isn't a watermark in there that will poi…

People say that HDFury splitter can remove HDCP 2.2.

Interesting, but if they used extracted keys from other devices, it doesn't change what I said.

> 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. 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…

To the contrary the analogy is apt because when one takes the socks you are not harming the next consumer (sure the cost of shrinkage is passed on) and there are lots of places to get socks. But the party that is well and truly fucked the most is the producer of the socks who will derive no benefit from work spent, designing, promoting, producing or delivering the socks. Your literal minded response suggests that, a…

> All of whom lose money when someone decides it's okay to steal a copy.

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.

Interestingly, that's less than a 50GB Blu-Ray, so tell me, why did we need a different disc format for UHD Blu-Ray?

Because Hollywood has higher quality standards than pirates?

This is just false, passionate fans are absolutely going to have higher quality standards than some hollywood executives.

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.

> Fans would easily spend on the roadshow cut of Hateful Eight or the integral cut of Kill Bill. Both are not available to buy. Why might that be? Maybe the market is too small. But in that case, why would they care about piracy? Strange.

Because it was part of the marketing campaign to get people to see it in the theatres. It was an experience that you were unable to get in any other way, and so it was more special and (theoretically) should draw more people to it.

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.

@spiderfarmer, the author can credit himself, all he has to do is put a "follow me on twitter @author" or something like that.

Videos are edited to remove that information. "Freebooting" is the term that's used. 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.

What you describe here sounds like a real copyright piracy.

I will pay 200gbp per month to the service provider that can provide 4k offline viewing with the variety of content available through torrent sites.

I bet there is not one legal service available online where you can view 4k media without streaming and without country specific restrictions.

> a typical cinema release is a pretty big file - frame-by-frame encoded as jpg2000 in 4k 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.

I work in the film industry, a 35mm full-aperture negative scan holds only about 2048x1556 pixels-worth, and even at that resolution the film-grain blobs are several pixels across (especially in the blue channel).

True and not true. I own few telecine and film scanning machines. Most of older film material, esp. 16mm isn't worth scanning over full 2k. 1556 in y on 16mm esp. important because lots of people want to reframe into 16:9 and 1556 gives more than 1080.

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
