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.
