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.

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 th…
> 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.
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…
Also, I would be surprised their isn't a watermark in there that will point to the cinema who leaked the version.

They get reuploaded to Facebook, where they go viral without crediting the author. If you're a content creator trying to build an audience, it definetly hurts when people already saw your content elsewhere.
> reuploaded To quote your ggp: > [re-uploading videos] _may_ classify as copyright infringement. [downloading YouTube videos] definitely does not. And your gp: > [Downloading YouTube videos] violates YouTube's terms of service and hurts the artists. And your parent: > Evidence required. So... why are we talking about re-uploading again as if downloading was the same thing?
I had to look it up. I won't post a link here but the file appears to be 38.06 GiB!
Interestingly, that's less than a 50GB Blu-Ray, so tell me, why did we need a different disc format for UHD Blu-Ray?
Still, 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.

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.

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…

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.

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…
Wow. That's truly insane. 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?
