But there is more to this than just colors. Take a close look at the
"Opening the West" banner. In the original, the banner is slightly
sagging in the middle, but in the processed frame, the middle is
slightly elevated. So there is some kind of optical distortion in
addition to the color correction and dirt cleanup.
For some reason, they've elected to do the comparison with frames that
are close to each other, but not the same. Check the positions of the
people at the right and left edges. It's not just different cropping
as their legs are in obviously different positions. Presumably the
banner just got Bob Dylaned over the course of however many frames
there were between the two.
