Grain is not noise. Digital is cleaner because your pictures and movies go through tons of filters before you actually get them on screen. 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.

Grain is in fact noise. Noise: Things that are not in the actual signal. > 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 - yo…

> At the microscopic level film pixels look like "clouds" of colored ink.

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.

Why does HN find it so difficult to understand such a simple concept? Obviously people will download it for free that otherwise would have paid for it.

To me, the only enticement of torrenting a movie is that it will be DRM-free. Please note that I don't mind DRM when used in streaming but I find it onerous when I "purchased" something.

I go out of my way to buy DRM-free. I buy on Humble/GOG over Steam (and often filter games my DRM-free), I prefer bandcamp and buying real physical CDs at bars. 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…

I am also a big fan of digital comics. I have an account of Comixology but I limit myself to the DRM-free books. Luckily, most of the comics I buy are from Image Comics and Fantagraphics; and they offer their books DRM-free.

> 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.

This is why there needs to be a law requiring sellers to support their DRM systems for a required number of years (after last using it making a sale). Either that, or require them to unlock the DRM for affected customer.

As it stands now, sellers can sunset a DRM system with no consideration of its users.

Ex VFX-er here. 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 ca…

DCP developer here. DCP track files are MXF. SMPTE ST 377:2004 (MXF) predates SMPTE ST 429-3:2007 (DCP Sound and Picture.) ST 377 is a normative reference of ST 429-3. There is no zip file. There is no central registration for encryption. Each Media Block has a 2k RSA key (usually generated inside the FIPS 140 boundary), and each content distributor has a collection of the respective X.509 certificates.

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.

Some first and second generation DCinema projectors are even 2K, these can still be found in operation. No, you probably won't notice... ;)

It always amazes me how people talk about theater snacks like they're mandatory or something. How about just......don't buy them?

How about just......make that policy about not permitting outside snacks go take a hike? 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.

Just find a theater staffed exclusively by bored teenagers who don't enforce the policy :)

> 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. 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 wo…

I actually carry a big purse when I go to the movies to keep everyone's snacks and drinks from the dollar store down the street, just for this reason. If the movie theater's snacks/drinks were reasonably priced, I would consider forgoing the dollar store and just buy it there to save time.

Keep in mind some theatres threaten an up to $1,000,000 fine for bringing outside food into the theatre. Silly, but I guess they feel it undermines their services?

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…

So DCP players in cinemas have to have access to a network? (or someone has to get the key and move it over via USB stick or something like that?)
