I don’t have the DVD copy of the movie, and I assume that the one on the Star Wars official YouTube channel is the best quality version of it considering it was uploaded more than a decade after the DVDs came out and could take advantage of everything that goes with that. If anyone has a direct, lossless rip from the DVD itself it might help, but I just don’t think anything will help it exactly match the surrounding footage.
Youtube definitely compressed it, though. The DVD version might not actually look all that bad compared to the Youtube version. They’re both 480p, anyway.
Color correction could also help make it stand out less.
