It was a couple hours of film, and it turned into something like 15TB. We did a job a few years ago for a client who didn't even want DPX, they wanted 16bit TIFF files, because TIFF is "more open". I feel like part of the reason we've been successful is that we've been able to give it to them straight, and counter the arguments they read on the internet that, while based on a nugget of reality, are often written from a non-real-world (theoretical) perspective, and are often outdated - and sometimes not even applicable to the situation at hand. I think the best approach to take is to go to a format that's not going to alter the original in any significant way (eg: don't backup to H264), and to expect to have to move those files every few years onto new storage media and potentially into new file formats.Ĭlick to expand.I spend a good part of my day doing this with clients and potential clients, actually. If someone thinks they're going to be able to easily open an image file 50 years from now, they're living in a fantasy world.Īs John pointed out, AMIA is a good resource, but you're not likely to find a single answer there, because there really isn't one. Migrate to new storage media every so often, migrate to new file formats that are compatible with current systems every so often. The only sane strategy at this time for digital preservation of media is to migrate, migrate, migrate. Case in point: 20-25 years ago I backed up a ton of personal stuff on ZIP drives. That ain't gonna happen with any digital format, for a host of reasons: Operating systems change, storage systems change, media formats change, file systems change. But the larger problem with the "proprietary" argument is that it's rooted in an old-school way of thinking about preservation: that you stick something on the shelf and in 100 years someone can view it. Something like ProRes is as close as you can get to uncompressed, without losing quality, and in a format that really isn't likely to go anywhere any time soon - even if Apple was to drop support for it today. Personally, I think the fear of proprietary formats is overblown. But after 3 years of doing their film scans, they have all the DPX files sitting on drives on the shelf, because they're too big and clunky to manage in a reasonable way. They upload the Quicktime files into their asset management system (this is a large university). One archive we do a fair bit of work for has us scan everything to DPX with quicktime access copies for viewing. We deal with a lot of archives and a lot of DPX files. There's no single way to do this because there is no good way to deal with this problem.
