That was using a 3" scope tube to
"write" to film, and then after
developing, to read it back again. I vaguely recall "flying spot
scanner" being somewhat related to this, I think there was some
equipment out there that'd actually take a 35mm slide. Though I'd
envisioned a roll of film, driven by a stepper motor.
It sounds like you were trying to reinvent the telecine machine.
Monochrome versions can indeed both read and write film using the
same mechanism and it tends to be claw drive rather than a stepper
motor.
