Reading this thread has made me realise what a job I took on when I offered to digitise the family home movies!
So far all I've done is replace the halogen lamp with an LED lamp, (which fitted perfectly), and browsed through the reels I've got to see which are worth doing. But when I set up the camera, a Panasonic GH5, the very first obstacle I encountered was, of course, the flickering image caused by the disparity between the projector's fps speed and the camera's.
The projector is an Austrian-made Revue LUX 5055 Sound, which has fixed speeds and an induction motor. So, a voltage regulator is useless, so I'm told. I'm the farthest thing from an electronics expert, so replacing the motor with a variable-speed motor is also beyond my abilities.
BUT, I had a bright idea. At the back of the projector, there is a knurled knob that protrudes, and is used for advancing the film frame by frame. I was thinking that a motor, (say, a sewing machine motor) might be attached somehow to this knob. It would require a mount and shims and so on, but I think I could do it. Then, the foot control of that motor could set the correct speed of the projector to eliminate the flickering.
How does that sound? Feasible or impossible or somewhere in between? :unsure:
