[FFmpeg-user] Digitizing Normal8 or Super8 films

[Michael Koch]

Is it possible to use FFmpeg for digitizing a Normal8 or Super8 film?
The framerate is 16 for Normal8 or 18 for Super8, but the motor speed of 
the projector may have 10% tolerance.
I could project the film on a screen and make a FHD video at 180 fps 
(with Panasonic GH5S camera).
There would be a small distortion because the projector and the camera 
aren't exactly on the same axis, but that could be corrected with the 
remap filter.
I haven't yet tested it. What I expect to see in the video is 
approximately 5 bright frames followed by 5 dark frames.
Is it possible to automatically select one frame from the middle of each 
bright segment?
Or any other ideas?
