The hair moves around relative to the lightbeam in 4K77. Maybe those are different frames?
That lightbeam, atleast the one that contains the hair, happens to be still. It doesn’t move at all.
I’m kind of confused on how else this would happen without digital manipulation… DNR and sharpening just don’t do that sort of thing. Everything else seems to match identically (besides the color, compositing, and transparency), except for the hair, which clearly shifts lone to the right…
