very cool pictures and comparisons.

by the way, my aspect ratio is off on a lot of pictures,

but that doesn't change the overall percentages i posted,

which is just for comparison. when i do crop the sides, you

are seeing the entire picture unless i mention it.

I was talking about my percentages. They aren't based on the actual amount of exposed image per se, they're based on the .839 x .700 aperture that was the standard for Panavision at the time. I am not showing 0%-5%-10% cropping of the total used picture area, I'm showing 0%-5%-10% cropping based on a projector calibrated to the 1977 standard Panavision aperture.

As I just demonstrated, some shots actually use the maximum sound aperture, which falls outside of the SMPTE protected area. A comparison of the GOUT to the entire exposed image will always show a higher percentage of cropping for those shots; for example, even if the telecine operator kept the framing in exactly the same place for this whole sequence, the closeup of Ben and the Mos Eisley matte painting would have a higher percentage of cropping compared to the full exposed picture, because the amount of exposed frame increases.

Your images do basically contain the entire picture. However, for my 0%-5%-10% comparisons, I need to be able to see the black space around the exposed image on all four sides. Looking at many of these full frames with soundtrack, the camera exposure seems to "trail off" on the left - sometimes you crop this off. I also need to be able to see how close the right edge is to the sprocket holes, because of the scenes that use more of the frame; for those shots, even 0% cropping at Panavision aperture would take off some picture on the right side.

I'm trying to demonstrate the maximum and minimum amount of image that would have been seen in a theater in '77, to provide a guideline for how you should do your cropping. Thus, I need fixed points of reference - that's why I would prefer versions with the complete frame, including the top and bottom frame lines, the soundtrack and the sprocket holes.

I can wait for more images. I'll still try to do GOUT/JSC/Technidisc comparisons, but until I get more full frames, my 0%-5%-10% will either be guesses, or will be 0%-5%-10% of the entire exposed image, or I just won't include them.
