I attended a great talk last night hosted by the Asian Film Archive. They brought up Ray Edmondsun from Australia’s National Film and Sound Archive to give a Q&A session about archiving, preservation and ethical issues in film restoration.
Some of the more interesting topics discussed were of course the film vs. digital debate. Of course film is still by far the best archival medium we have. Properly stored, it can last over 100 years, and the technology to read it is easy to reconstruct all you have to do is simply shine a light through it.
So my question was, if film is the best archival method, what is the second best for digital assets? The answer was there wasn’t one. Things get trickier when you move into the digital format. Tape or Hard Disk? Will that tape or disk format even be readable in 30 years even if the media survives? What file format to store it on? Essentially while film is a long term archival solution, digital requires a constant migration from format to format throughout its life. The downside of this is that it’s very likely that somewhere along the way, someone won’t migrate it fast enough and the data will be lost. The upside is that digital distribution means that it’s easy to propagate many copies around the world rather than striking film prints. Archiving digitally is a moving target.
