It seems someone decided to remove the banner from the video frame. Have a look at the left guys hat, there is a little "v" from where the banner was (in the top red oval).
The image cannot be the result of seam-carving because SC does not result in duplicated patches of the region. Moreover, the patching up (as others mentioned, to remove the scores) results in both non-zero offset both horizontally and vertically, which will not happen if you run SC (you'd expect either horizontal or vertical movements).
This was either a quick hack job by a person, or the work of an extremely sophisticated machine vision program.
