TESB blu-ray has 3 scenes that differ from the DVD. The red on the Wampa’s arm is removed. A reflection added to the exterior shot of Leia in the tower in Cloud City. And Some lighting changes when Chewy finds C-3PO. The first one is a nice fix and is well done. The second two are clumsy and I can see the tell tale signs of what they did so they go. Neither really take you out of the film. I might reconsider that shot of Leia in the tower, but that would involve editing to remove a section of reflection that is outside the window area.
I’m really only trying to fix the flaws in the SE the have crept in since it was released. Some of the DVD and blu-ray changes fix things and some outright change things. The fixes I like to keep, the changes not so much. The only thing I want to keep is the link to the soundtrack which means going with any changes that impact the soundtrack. In ANH that includes the edit to the Han/Greedo scene. They extended it 4 frames and cut 4 frames from the end of reel 1 so the movie runs the same time in DVD and Blu-ray, but from the start of reel 1 until Greedo is shot everything is 4 frames off. Easier to leave the better cut of the Han/Greedo scene alone. Like I said, this is a hybrid restoraton. Kind of a DVD/Blu-ray intermediate. I can also turn on all the changes to the DVD and change the soundtrack and make this a pure restored DVD edition if I wanted. I’d rather make the hybrid - the best of both. I have some rendering to do in the next week and hopefully after that I can make an OT demo video.
