I've had good luck using my Epson V600 picture scanner, which scans slides / negatives / photos and documents. I pretty much use it to cover all my scanning needs. I also have some Super 8mm video (with sound), but didn't find a digitizer that handled sound with the video(non commercial). I did purchase one of those 'step' frame-by-frame' 8mm/super8mm machines (expensive, but worked ok). I still have my super8 mm projector (with sound) but it's on it's last leg. Tried digitizing video directly from that (little box with mirror in it) and a camera, but the video was terrible with flashes of light from the projector frames. So the frame-by-frame step machine, I was able to get decent video, and used the projector to grab/record the sound - then used (free version) Davinci Resolve to put the two back together (join sound/video)... only problem was the different speeds, I got 'some' sound drift (sync to video).. but got it close enough through adjustments where you probably wouldn't know it unless you knew it was off. That was the best I came up with for my 'do-it-yourself'
