Kodak home movie film has always been safety film. AFAIK, film from the 50's and 60's would be cellulose triacetate base. If the film was stored cool and dry and in air-permeable containers (e.g., boxes), it should be in good shape, except for slight shrinkage. If stored improperly (hot, humid, sealed containers), there may be the onset of "vinegar syndrome" where hydrolysis causes the base to degrade and release acetic acid vapor:

The question on transfering to video is...what form for storage? I don't mind shelling out for a good telecine job to get it to a digital medium that exceeds the 8mm resolution, but I want the transfer to be something that will indeed freeze the quality. I don't think DVD will do it for me...I'm not "that" impressed by it.Steve ------------------

Oh yes I agree, which format indeed. Similar problem with audio on magnetic tapes. At the moment there aren't too many choices for video material, unless you want to spend a small fortune. I mainly want the DVDs so family and relatives can watch them without the danger of further damage to the films. Also you can skip through the really boring stuff which you cannot do when projecting film. So yes John, I do intend to keep the original films and store them as best I can. Thanks for the tips in that regard.So what is the best way to apply FilmGuard to 8mm stock? ------------------

Oh, I agree that DVD or even quick time is fine for distribution to family members. But what I want to find is a good medium to get them in the digital domain. Then as technology marches on, rather than go back to the telecine, convert from today's digital medium to tomorrow's. I would NEVER think of throwing out the films so long as they are runable. As to Kodachrome looking good after the many decades...you bet! That was an exceptionally designed film. Steve ------------------

Quick point: as far as I know, all camera films (with the exception of some high-speed and special military applications) are on acetate- or nitrate-base stock. This applies to all formats (8mm->65mm) through to the present day. ESTAR-base stock is only for intermediates, separations, and some (mostly recent) prints (and the aforementioned special-purpose stocks).As for video format, I'd be interested in this as well. Hopefully there is someone here who is familiar with the current state of 'rust' (as Josh would call it). I do know that compressed digital formats (DVD, DV tape, Digital Betacam, etc.) are generally frowned upon by archivists. I have had some of my attempts at 16mm filmmaking transferred to Beta SP and dubbed to 1" tape for duplication to VHS; it's a great format and is ubiquitous in the professional world, but has recently been end-of-lifed by Sony and thus may not be the best long-term choice for storage. Apparently 1" C-type is almost dead now in the television world and it was the major broadcast format through most of the 1980s (and it's a better master for dubs than Beta SP). Personally, I'm not too worried, since I know that 16mm original negative (and prints) will outlast any of today's video formats, but I agree that it's a good idea to get a high-quality video master as well.
