That's a fascinating video. Although two things really surprised me.

Firstly, I can't believe how bad the original negatives were, sure they've aged. But it seems like they're admitting they weren't that hot to begin with.

The second thing is that despite the wonderful new world of digital media, they're still printing back to 35mm stock. Digital obsolescence continues to astound me, in 30 years time there probably won't be single working HDCAM-SR deck to play the digital masters they've created, but they'll still be able to view the film stock. I would've said 40 years, since there are U-Matic machines from 30-odd years ago that are still working, but to be honest, they don't make 'em like that anymore. A lot of the new kit becomes junk as soon as the highly custom silicon in them fails.

I've got decks that are less than 10 years old that can't be fixed as Sony have stopped manufacturing some of the IC's in them, and it's not economically viable to buy a junker to strip for parts.
