@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.

> 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).

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.

That was a long time ago. You can get consumer 4k projectors for under $10k. Here's one for example: https://amzn.com/B00SKK70VO

But this can't play DCP. Also the gamut is Rec. 709, instead of DCI-P3.

So... why are we talking about re-uploading again as if downloading was the same thing?

I never said all downloads are hurting content creators. I am saying if it was not possible to download them, the creators would be better off.

Sure, and if companies wouldn't have to pay taxes, they would make more money.

If perfectly legal, permissible, expected and ethically justifiable behaviour hurts your bottom line, your business model is broken, not your customers.

It's worth noting that the DCP format doesn't have a master key - each "reel" of an encrypted film has its own content key, which is decrypted by each DCP player's private FIPS protected key combined with a public Key Delivery Message from the distributor. 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 cont…

> 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.

Still, a 'low-end' Barco good enough for smaller cinemas is definitely less than $100k these days.

Times are changing. I am very happy for these new developments.

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.

The point of DRM is to make that time, motivation, and quality equation not make sense. Every day that a new videogame stays off Piratebay is an extra day of full revenue. I'm not defending DRM, but it's important to know one's enemy.

Is that true, though? I'd expect that the people who only download cracked games will wait for the game to be cracked and up for download, no matter how long that takes. The people who download games to trial them and then buy the ones they like will likewise wait until they can give it a shot before potentially wasting money. The last group, those who buy legit copies of games at or near release, are going to buy it…

There actually are people who would pirate a game but then buy it if it's not available for download. I suspect they're a fairly small group though. Too bad we don't know how large it is in comparison to the group of people who don't purchase before they get to try a (likely pirated) copy, or the people who don't buy games with DRM (I'm mostly in this group).

Tell that to the pirate encoders who had to deband movies because the official releases were so bad.

In the early/mid 2000s there was a whole scene around manually applying inverse telecine to badly produced commercial anime releases, with custom tools like YATTA.

Don't get me started about pre-widescreen episodes of Family Guy. I don't know how they ruined them, but they're all ruined with horrible, burned-in interlacing artefacts.

Apologies it does sound[1] like an absolutely perfectly shot 35mm frame can theoretically hold up to 20 million pixels-worth, but I've never seen this in practice in the vfx industry, it's almost always less than the ~3 million pixels that 2048x1556 provides.
