To follow up on the status of this project a bit:

At the moment, I am re-timing the alien subtitles to match theatrical timing. For Star Wars, this isn’t a very big deal, and Empire has no alien subs, but for Jedi, the difference is actually pretty big. In Jedi, the timing of the subtitles varies quite a lot between theatrical prints and various home video releases. At least as far as I’m aware, until recently, we’ve never had a complete, authoritative reference for exactly when these subtitles appeared onscreen–we were able to get a few from the Empire of Dreams documentary, but the rest involved either some guesswork or just using Laserdisc/GOUT timing. Now that we have a good reference, it’s easy.

The problem is that if I release the re-timed project before any preservations actually use theatrical timing for the alien subtitles, then Project Threepio’s timing will just seem off, sometimes badly so. So while you may hear a bit about various updates being in the pipeline (improved Finnish subtitles, for example), I’m not likely to make any of these updates available until closer to the release of a major new preservation of Jedi, whenever that will be. I imagine all future preservations will use theatrical timing for the alien subtitles, because now there’s not much reason not to.
