It also makes a difference you want to sync to the US or UK version of the GOUT - they differ by 3 frames. The UK one has 2 extra frames at the beginning and 1 extra at the end of reel 5.

I beg to differ. The only additional frame that contains data shows the tech motioning with his hands to lower the green R2 unit into an X-wing and in the very last frame (missing in the US GOUT but not the Definitive Edition LD’s, the DVD or the BR) his hands curl fully. I’ve checked the Hyperspace and Rebellion sets as well as my own DVD’s It is only 1 frame. Now, the two frames at the beginning could be a ripping error, but I get it consistently so I’ve run with it.
