600 PowerMacs Make One DVD 269

Great, so he's doing optical at 4000 lines per inch.
But what about the sound? Is he using non-compressed 24-bit samples at [at least] 96KSS [kilo samples per second]?
Your ear is a vastly more sophisticated sampling device than your eye; I don't know of a single sound compression technology on the market that can fool the human ear.
It would be a real tragedy to go to all that trouble to make good digital copies of the optical prints, only to try to cheat on storage space by downgrading the soundtracks to one of these abominable undersampled, compressed audio standards.

High res for detail, but not as crazy as dozens of pixel sized film grains

I would imagine that, as with anything else that has components that can be categorized as either "good" or "popular", sales of the "popular" stuff will subsidize the production of the "good" stuff.
Face it - they're going to sell more copies of "Dr. No" with Ursula Andress [imdb.com] wearing the New & Improved High Resolution Digital Bikini than they are of Singin' in the Rain, starring Gene Kelly [imdb.com] and the Incredibly Vivid High Resolution Raindrops.

Who's gonna bother to steal it (it being hundreds of gigabytes) and then downscale it to regular resoluiton for hours just to have something at the same quality that's available at blockbuster for $5?
Or are you implying that people would like to download the original and store it on a terabyte disk array?

Um, no it isn't. Your eye is vastly more sophisticated. Is it easier to recognize people by their faces or thier voice? Even musical instruments, is it easier to tell what kind of instrument is being played by looking at than listening to it.
And there isn't any technology that can "fool" the eye either. When you look at a picture, you don't think it's real, you know it's a picture. Just like a recording, except a recording can come a lot closer.
Super-hardcore audiophilia is a bit of a religion.

Some back-of-the-envelope calculations assuming a 4000x4000 image, 24 bit color (too low?), lossless (optimistic) 4:1 compression and 24fps show that a 2 hour movie takes up over 1.8TiB.
Is it just a box of 300GB tapes, or do they have something even cooler?
Can you imagine the restore times for a movie from tape...

Artists have known since at least the time of Rembrandt [i.e. almost 400 years] that the human eye can be fooled into seeing what it wants to see; in the case of Rembrandt and his pointilism, the eye [or the part of the brain responsible for processing data collected by the eye] merges small dots of color into a larger whole that it would prefer to see.
You've just described compression. A particularily artful, beautiful form of compression (especially Monet,) but it's compression nonetheless. You just proved point the previous poster made: nobody is going to be fooled into believeing that a pointilist painting is actually a scene taking place in front of them. You may admire it for its beauty, for the technical and artistic prowess required to render it to the canvas, for any number of reasons. But it's not a "perfect" rendition; if you 'believe' you're at the seashore any more or less than you would by staring at a photograph of the seashore it's an emotional decision, not a rational one. And you certainly wouldn't settle for seeing James Bond rendered in a pointillistic style for two hours, not when you know you can see it in all of its Technicolor glory in the next theatre over. It's different -- it's an art form.
Now, there's almost nothing artful about audio compression. (I say almost because there are artists applying all sorts of distortion to their sounds to create new ones, including overcompression.) For the most part, the distortion caused by compression is just a nasty side-effect. But the ear is indeed "fooled" by the compression. When you listen to a compressed audio stream, you hear music. It may be poorly reproduced, tinnily digitized, and companded down to the level of a phone line, but you still hear the music behind it. That's "fooling" the ear -- at least as much as pointilist art "fools" the eye (and without the art.)
Anyway, setting all "golden ear" arguments aside and getting back on topic, I very seriously doubt they'd use compression at all on the audio. The imaging they're doing on each frame is lossless (each frame is probably around 40MB RAW), and this guy didn't get funding for 800 Macs by being stupid and cheap.

Anyway we are talking of scanning camera negative and the sound had never been on the camera negative.
