There’s a tutorial for using fiducials for alignment: Passthrough Alignment Tutorial with Manual Indexing
@palmercr conjectures in that thread that you could do something similar with a sawtooth cut into the jig and then progressive sawtooths into the material to match up every 10". That is, you cut the next sawtooth into the left edge of the continuous material as you cut out that section of the material. Slide it forward 10" and place it on the jig sawtooth and cut the next frame along with the next sawtooth, etc.
