@Robert Withers, I found this old thread and I’m curious to hear what you ended up doing?
I would like to archive my 200h super8/mini-dv/vhs video in a format that’s also suitable for editing, as encoding to a new codec takes many hours for just one videotape on my rather outdated computer. And also just for simplicity. I don’t get the idea of archiving in both ProRes AND FFV1 – that brings up the total storage to a level where you could just as well save it all in an uncompressed format.
All together I’ve been surprised by the large file sizes even for compressed files with these lossless or near-lossless codecs. When starting digitizing I thought H.264 would be just fine, and that’s also what most home movie digitizers use. But it would be a pity to realize that in 5-10 years valuable info has been lost that could have been used for new technology that may appear, to utilize the old footage in new ways. I expect that AI-based tools that can bring old footage up to perfect quality will appear in few years.
