jumpinjan,
I often convert 8mm to video at work. There are two ways of doing it: scan each frame, or record the film playing. The first way makes a higher quality video, but can end up being expensive, although I think the price has been gradually going down. Do a google search for
film video conversion and you should come up with a
few sites. They will often charge you a minimum of 600 feet at about $.30 USD/foot, which probably doesn't include the cost of putting it on DVD or mini-dv. They will offer "restoration services" as well, but what they do actually decreases the amount of data in the video by compressing the exposure range and by using sharpening filters like in Photoshop. What I do is simply play it on the projector at a proper speed and record it with a mini-dv camera and convert it to any video format. It usually looks fine for standard definition video and is cheap, but sometimes it will flicker a bit more due to small differences in frame rates between the film and video. I'll be willing to do it at material cost if I can add the movies to the Internet Archives (if they're not there already), Google Video, and Creative Commons for others to look at.
