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…

A small battery, dedicated to tamper-detection, should take care of that.

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…

And they still look bad. smh

Pretty much any digital cinema projection suite will be able to play your run of the mill quicktime/h264 file, so DCP is hardly a requirement to watch cat videos on a cinema screen.

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.

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.

I agree in principle, but I think the adage that "Every day that a new videogame stays off Piratebay is an extra day of full revenue" is a bit of a false equivalency.

There is almost a controlled experiment here (similar data to many economics papers).

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.

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

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.

Shouldn't you already have the source videos for you channel?

Backing it up from Youtube is likely a better solution since he doesn't have to upload everything twice on a (probably) slow uplink ADSL line.

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. 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 EN…

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.)

I would not say a brute force copy must be necessarily lossy by default.

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.

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.

Thing is, I'm poor, and it was roughly 3x the cost of the discounted ticket I usually use.

At minimum wage I would have paid about a day's salary, and thus I "boycotted" it.

> 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…

You miss a very key point. What percentage of sock sellers buy socks if they can't steal them? The number of people who pirate digital content that they would otherwise have bought is a lot lower than 100%. Another point. And some of the Pirates already own what they are pirating. I've pirated content that I own as I'm not allowed to stream from a DVD drive in a computer I own to a tv I own for some reason. Piracy is also quicker than ripping old DVDs to a format that is actually useful so I'm happy to acknowledge what I get up to. A better example would be someone copying the sock exactly and using this copied sock. Yes, this violates rights of the original sock designer and manufacturer, but it doesn't actually take their sock.

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

Yes
