I couldn’t help myself. And in the process I found out I was wrong. The SE end credit music does repeat itself, but it has needs two other edits to make it match the original. I unfortunately don’t think any of the 97 SE can be upgraded to full 1080p so I did it at 720p. I had to add a bit of grain to both the 97 SE and the BR to make it match the 4K83 that I was using, but it looks to be a fairly good match.
So where I cut from 4K83 was when Luke has lit Vader’s pyre and it switches from Luke’s face to the distance shot of him standing in front of the pyre that then pans up. From there it is the 97 SE until it pans back down to Endor again. Then I put in the BR until Luke sees the Force Ghosts appear. Then back to 4K83, but I cut it to match the 97 SE and BR. What they did was split the one shot of the ghosts and insert the first part of Leia coming to get Luke. So I matched it and then goes into the end Credits.
For the audio, I only was working in stereo. I changed the audio earlier than the video. I did it earlier in the funeral pyre sequence, toward the beginning before the music starts. And then it is the AC3 sourced audio from the 97 SE LD. There are three edits to make it match the sequence and running time of the GOUT audio for the end credits. I’m rendering the end sequence (from where Luke flies out of the Death Star) to upload to see what you think.
And I should point out that the 97 SE version I am using is my own. It is upscaled and I think it matches pretty well. The BR shot of Tatooine has more color to it, but the original 97 SE shot of Coruscant has more color (that sequence was also edited to show the PT version of the Jedi Temple and Senate for the BR). There is some missing to be able to cut the BR to match.
