HarryCaul writes: Movies are moving to digital, but what about long-term archiving of the master source materials? Turns out it's harder for digital media than for contemporary analog. Data is being lost, and studios have to learn to cope. Phil Feiner of the AMPAS sci-tech division says "when he worked on studio feature films he found missing frames or corrupted data on 40% of the data tapes that came in from digital intermediate houses" How to deal with it? Regular migration from old media to new media. Grover Crisp, says Sony has put in a program of migrating every two to three years. Other studios are following suit, but wht about indie features? Will we lose films like we lost the orignals of the 20s?
