With terabyte hard drives now available for $100-200 (last time I considered this project, they were around $1,000!), I'm thinking again of a major VHS conversion project that would start with about 100 hours of tapes. I figure that once the files are edited down to about 45 mins. each, I can export uncompressed QuickTime from iMovie and it will all fit on a terabyte drive. Is uncompressed QT a format that should have a decent shelf-life? I realize that it's been around for a long time now, and AFAIK is not likely to disappear any time soon, but when I first thought of this project, DVDs seemed like a sure bet, too, and now those are starting to face extinction. (Although not right away.) However, I would think that any compression format would be in even greater danger of obsolescence than uncompressed QT, so that probably is still my best bet, yes? BTW, Jeanette, I also use a Canopus A/D converter between my VHS machine and my Mac. It does what it's supposed to with no muss, no fuss. Patty
