Here is how it's done in photoshop:

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).

There's an even better version that works with video: http://www.faculty.idc.ac.il/arik/site/seam-video.asp

Hmm I remember seeing that video before. Extremely clever technology.
