There was speculation on these boards as to whether or not the ‘97 cg shots were transferred directly from the digital filmout tapes for the 2019 4k version à la the 2011 rebuild of TPM or if they were simply scanned back in from the negative just like any other shot in the movie.

There was also speculation somewhere (maybe it wasn’t here) that the ‘97 re-comps were re-done from scratch yet again to take advantage of the higher resolution.

Has any evidence emerged to support either of these theories?
