John/Greg, if you were intent on ARCHIVING something in digital, I don't think you're gonna compress it into MPEG or DIVX. And surely when the file "migrates" it's not going to be recompressed. That would be stupid. The storage mediums aren't there yet, but they will be very, very soon. I submit to you that digital data can last LONGER than film with absolutely ZERO loss from the original source.... EVER!
I was speaking in terms of the technology that is practical today, where some degree of compression is still needed to economically store the huge data files needed for a feature film.
"Film is Future Proof" in the sense that it is certain that there will be a way to transfer it to any future display medium. When decades-old movies and filmed television shows (e.g., "I Love Lucy", "Hogan's Heroes") are being scanned at 4K today for use on HD television outlets (including future HD-DVD), it was a market that was never envisioned when those shows were made. But even fifty-year-old film has the image quality to meet the needs of the most sophisticated electronic display technologies today, and tomorrow.
At ShowEast, when Sony wanted to show the capabilities of their 4K SXRD Digital Cinema Projector, they used filmed scenes from "The Music Man" (8-perf 35mm film) and "The Sound of Music" (65mm film), which had much better sharpness than the clips from Star Wars Episode 3 in the same demo.
