I saw your video previously and I understand how it works. Maybe I misunderstood your comment in your previous email: "> Hello. > It's written in video description." It sounds like you have a written description of video processing. By the way, another member did a similar setup but for film and he wrapped it around a drum like an ancient fax machine. There was also a member that converted an inkjet printer to a direct photo plotter. I really like your solution.
