While waiting for the authentic German sound-mix of Special Edition 1997 to turn-up, here is an alternative you can use from the existing 2011 Blu Ray mix.
Both the 1997 and the 2011 Blu Ray cuts are of the same length for the first 2 hours, 5 minutes and 55 seconds. It is when you reach the Victory Celebration that the cuts go out-of-sync with each other as the 2011 cut adds 5.626 seconds during that sequence–it would be in the Naboo footage where a gungan says, “Me’s a free!”.
All you would have to do is trim-out those 5+ seconds, apend the two parts together, and boom!–instant 1997 length–provided that the G’ker version is frame-complete.
Thank you for the info, but i already done this, but with the 2004 Mix.
And also i slowed it down from 25 fps to 23,976fps, because i don’t like PAL-speed up.
