Way back in page 1, -1's initial GOUT vs. raw cropping overlays seemed to suggest that the GOUT framing zoomed in as Han was chasing the stormtroopers down the hall:

Later, I contested this, saying that I didn't detect any framing change during the scene when I compared the GOUT against the Blu-ray.

Now that I have the red reel tests to reference, I can come up with even better GOUT cropping estimates for those scenes. Here's what I came up with for those two shots, using my technique of eyeballing where the edges of the GOUT image are in the uncropped frames.

Here are my estimates, by just comparing one frame to its GOUT equivalent:

The positions of the left and right edges don't match, but that's mainly because the combination of the motion blur of the scene, the DVNR smearing of the GOUT, and the compression of the test clips made it hard to find the left and right edges of the GOUT vs. this clip. But in general, it matches my comparisons from the reel 3 LPP images - the GOUT is framed toward the bottom and to the right.

Then I decided, why not make a more definite comparison using a more static shot, with more clearly visible "landmarks" on all of the edges? So here's a shot from earlier in the scene:

Again, it basically matches the "down and to the right" cropping of all my other GOUT estimates. Next, I decided to map this box over the images of Han, and here's what I came up with:

They fall in basically the same area as my initial estimates, further evidence that this scene is not as cropped as -1 thought, and that the cropping stays in one place.

Next, here's that shot of Ben walking down the hallway that -1 thought was extremely cropped in the GOUT:

I thought this seemed fishy - the proportions don't match (the GOUT overlay here has aan aspect ratio of 2.76:1!), the two images don't line up well, and I could not believe that much would be cropped at the bottom.

-1 just put up a test clip with this shot, so I decided to do another estimate. This one was even harder, because all four edges are dark, and the test clip is so crushed and compressed. Without any "landmarks" on the edges of the frame, I really had to eyeball it. Here's what I came up with:

As you can see, my estimate shows that it's no more cropped than any of the other shots I've tested. -1's initial comparison was just very inaccurate - no offense to him, of course. Those comparisons are what got me thinking about the GOUT framing in the first place.

Now, here's the same shot with the cropping estimate from that stormtrooper image mapped over it:

Again, it is very close to my first estimate, and it basically matches all my other estimates of the GOUT cropping area, framed toward the lower-right of the raw image.

And here's a shot from the uncropped, uncorrected test clip, with the approximate GOUT framing as a blue box:

Yes, the GOUT is cropped from the raw film frame, just like any video transfer. However, from what I'm seeing, it's not as severe or as inconsistent as it seemed from -1's initial comparisons.
