No idea but if it helps, here's that first shot from the raw GOUT, with only the black bars on top and bottom cropped:

You'll also see that there's a little more on the left than in our final version but that's because a few pixels on the left side have strange stuff going on during the film like there's sometimes a blue line there or no colors and so on. It looked better when just cropping that little area away.

EDIT:

Found some raw PAL GOUT SW screenshots and from what I can see when layering them on the same NTSC shots in photoshop, they're cropped more on all 4 sides!

EDIT 2:

Here's a comparison. I cropped the black borders on the sides of NTSC GOUT for this one. I resized the PAL frame to match the NTSC one, and left black bars around it. You can clearly see it's missing some pixels:
