Okay, two things relating to the video below, since when do pilots dress casual?? Does anyone have any idea why this landing gets so rough AFTER touch down and reversers are on?

The approach seems smooth and coordinated with no apparent crosswind.

You can tell it is not just the camera shaking because you can see the people actually moving in their seats and you can hear the pilot groan...

Any one have suggestions?
