Project files have been updated to version 13.0 (codename: “Endurance”), and the first post has been updated. Please PM me for temporary download links until the files are available at some more permanent locations.

Project Threepio has now been providing subtitles for the Star Wars Original Unaltered Trilogy for more than ten years!

Rough summary of changes from 12.3 to 13.0:

Added new language: Afghan Persian (Dari)
Changed language code for Iranian Persian from fas to pes, to better distinguish between various forms of Persian
Added Canadian French subtitles for ROTJ (thanks to schorman13). Under normal circumstances, I don’t add subtitles that aren’t trilogy-complete to Project Threepio, but it appears at the moment that there are official Canadian French subtitles available only for ROTJ, and I prefer for there not to be any reason for anyone to feel obligated to ever watch a Special Edition, if I can help it.
Improved Dutch subtitles (thanks to frater)
Added Urdu and Polish titles-only subtitles to accompany dubs (the Urdu subtitles are to accompany the Hindi dubs)
Modified Indonesian titles-only subtitles to accompany complete dubs
PGS subtitles now have limited support for cropped video (i.e. video where the black bars have been removed). Some background: graphical subtitles are designed to work only with a 1.78:1 video frame, and their behavior with video cropped to a different aspect ratio is not defined. Playback software can deal with the aspect ratio mismatch in different ways, potentially resulting in a variety of non-optimal results. Project Threepio’s scripts now allow you to alter subtitles so that they look normal during playback with cropped video, but that process works only for specific playback software. The best solution for cropped video is still to re-encode the video with black bars, expanding the aspect ratio to the expected 1.78:1.
Hypothetical 24.000fps preservations are now fully supported in all included scripts and documentation, although all included subtitles are 23.976fps, as always
The render script can now use Python’s Pillow module for improved speed (but it is still extremely slow by any reasonable measure)
Improved cross-platform compatibility for all scripts (this was so badly broken before that it could be considered a new feature)
Fixed some bugs in the render script, and re-rendered all subtitles
Improved the algorithm that estimates the position of “unshifted” subtitles in various scripts
Reorganized some files (most noticeably, the sup folder has been renamed the pgs folder, and native subtitles have been renamed localized subtitles)
Pre-rendered PGS subtitles are now included for all pre-1997 film variations except the 70mm cut of Empire (if needed, 70mm subtitles can be created using the provided instructions). Be warned, this means the total size of Project Threepio is much larger than earlier versions.
Pre-rendered 720p subtitles are no longer included with the project files. 720p subtitles are still supported and can be created using the provided instructions.
