Reviewed the DIF of ROTJ 2004 vs 2019 and below are some for consideration.
- Reframing of the intro SW and Crawl higher in the picture frame. Lucasfilm compensates with a modified pan at the end of the shot when the Death Star rises from the bottom of the shot.
- The back of the Left Imperial Officers has his shirt painted black.
- Multiple shots in the Jabba sequence appear to be stretched or have a zoom which might affect the pixel aspect ratio.
- A shot of the Rebel Fleet has a missing ship added back in and an edge crop fixed to show the Mon Calamari cruiser all the way to the end of the frame.
