Right, but the subtitles in Star Wars are not burned in, they’re a composite. That’s why they have a shadow. Burned-in subtitles look like this. It’s where we get the “burned-in” phrase from - they’re literally burned into the image after the film has been developed.
The fades were done optically for the SE but all of the composite shots were done digitally.
I disagree, it was a photochemical restoration, while the optical wipes may have been digital, they re-comp’d other stuff optically.
