Starting RotS, looks like some of the Wookiee homes have a darkened roof.

The intro shot of TPM is shorter, could be another German crawl variation. Since TPM has this 8% more frame (doesn't seem to be the case for all shots. Many look shifted right, others the scale is noticable, others like Jar-Jar leaving the swamp later in the movie look the same) using this as a quick test to see how many shots can be done quickly.

The yellow box is the 2004. Have a somewhat close match on the approach. Then the 2004 shot is extended. The problem is the next cockpit shot seems to be 1-1, there is no lost frame. So I jump back to the beginning of the cockpit scene, and attempt to establish the scaling of that shot.
Contemplating what to do next, just out a copy to look for scaled shots or progress slower with the idea of finding changes which wouldn't be apparent until after the scaling is done....
