You are right: the slide feeder works as you imagene, but if you have a
negative stripe, then you have to position on a variable offset from the
start of the stripe. The offset depends from how the camera moved it
when shooting, or based on the way you cutted the image.
This means that there is no fixed offset for frame, but there are
backend that coud accept an offset as parameter.

This offset require an interaction between user and backend.
