As reported by Michael Cieply in The New York Times a while back, films that are “born digitally” — that are digitally produced, edited, distributed and projected — are never really fixed in any solid state medium. They’re just pixels and electrons that have to be moved from one platform to the next.
As Cieply wrote in 2007, “Time was, a movie studio could pack up a picture and all of its assorted bloopers, alternate takes and other odds and ends as soon as the production staff was done with them, and ship them off to the salt mine. Literally.
Having figured out that really big money comes from reselling old films — on broadcast television, then cable, videocassettes, DVDs, and so on — companies like Warner Brothers and Paramount Pictures for decades have been tucking their 35-millimeter film masters and associated source material into archives, some of which are housed in a Kansas salt mine, or in limestone mines in Kansas and Pennsylvania.
It was a file-and-forget system that didn’t cost much, and made up for the self-destructive sins of an industry that discarded its earliest works or allowed films on old flammable stock to degrade. (Indeed, only half of the feature films shot before 1950 survive.)
But then came digital. And suddenly the film industry is wrestling again with the possibility that its most precious assets, the pictures, aren’t as durable as they used to be.
The problem became public, but just barely, last month, when the science and technology council of the Academy of Motion Picture Arts and Sciences released the results of a yearlong study of digital archiving in the movie business. Titled The Digital Dilemma, the council’s report [offered this] startling bottom line: To store a digital master record of a movie costs about $12,514 a year, versus the $1,059 it costs to keep a conventional film master.
Much worse, to keep the enormous swarm of data produced when a picture is ‘born digital’ — that is, produced using all-electronic processes, rather than relying wholly or partially on film — pushes the cost of preservation to $208,569 a year, vastly higher than the $486 it costs to toss the equivalent camera negatives, audio recordings, on-set photographs and annotated scripts of an all-film production into the cold-storage vault.”
That was in 2007. Now, in 2012, just five years later, everything is digital. But the problem remains the same. There are more movies being made than ever, but they’re not being shot on film — they’re digital. How are you going to archive them? What do you do when a digital platform is phased out, as DVDs now seem to be heading for their final spin?
The most practical solution might well be to simply make a fine grain photographic negative of all the film’s original materials and bury in it in vaults — cheap, easy, and reliable. Some preservationists suggest that film buried deep in cold storage vaults can last for hundreds of years without a problem.
Can you say the same for a digital production?
