As someone who teaches electronics and studied film (including the handling of the actual material) I am more confident that the roll of film I first shot will survive the next 200 years than I am in the survival of that prores mov I stored on two hard drives of my latest film. As far as I know film is what the National Archives have chosen for the archival of all relevant movies even if they have been shot digitally and I guess they know a thing or two about archiving. A computer that plays back a Prores file has so many more "moving" parts it is not even funny. You have the spinning rust that may or may not be faulty, then you have the read head that may or may not be faulty, then the spinning rust has a disk controller on it, that may or may not be faulty, then you have a connector on that drive that may or may not exist anymore, then you have a filesystem on that disk that may or may not be supported anymore, and then you get the container format, that may or may not be supported in that version anymore and you get the CODEC which may or may not be supported anymore. But from the outside it just looks like a hard drive. Unless someone really made good labels and they are readable, and you trust the label you won't even know what is on there and if it is worth all the hassle. Meanwhile with a roll of film or a photograph you just see the thing that is on there. It might have scratches, be half rotten, faded colors and all, but in many cases such things are still somewhat "readable" after a century of bad storage.
