I’m not sure what you mean saying that the light beams move at different speeds. They don’t seem to to me! The light beam that is in a different position in the gif you posted is NOT moving in either clip. Yet it moves more in your gif than the hair does. We should get to the bottom of this.

They are different thicknesses and transparencies… I wonder if differences in the fidelity of the films and scans, the cropping, or post-processing effects like sharpening/DNR might have something to do with it? Maybe that could also explain why the hair seems to move a little! After all, the specific way it moves really reminds me of comparing the same frame from, say, Harmy’s Despecialized and 4k83. Seems less fucking insane than Lucasfilm editing in a pubic hair for no reason.

Sweet baby Jesus of Nazareth…
