This cleanup and restoration is a separate project. Mostly, it arose due to convenience, and as a test of the cleanup to show the results to people. This was on the side, so as not to be a distraction away from the restoration of Star Wars.
The best preservation will be the one using the FUJI print which is slightly faded and has the least noise and artifacts.
That will be done on it's own timeline, and by different members.
Ultimately the source will be in 4k, and downscaled, due to practical reasons. The same will be done with Return of the Jedi. We will not be releasing Raw scans for any of the films, because it's too unwieldy to distribute.
These will be the highest quality restorations of the movies to date. Since there is only one other project that will be working on them at a later point.
