Sorry, no real progress. It's time consuming and I haven't spent much time on it lately. I will get it done one of these days. This weekend I tried a different approach out of curiosity. I tried taking a picture of the frame with my camera, but my lenses aren't macro and the resolution would be too low. It would be great if I could scan each frame quicker that way, but it won't happen.
This is where I am at (starting at the end and going backwards).
