Although it's set up differently than the D7000, the D5100 also has a great layout for the occasional video shooter. The switch on the side of the mode dial toggles between regular and Live View/Video mode, so you don't have to use an awkwardly placed mode on the dial. And the record button is in a great spot by the shutter; it's easily reachable with your forefinger, but not in a spot where you're likely to hit it by accident.
For the D5100, Nikon added Effects to the mode dial. Your choices are Night Vision, Color Sketch, Miniature, High or Low Key (which really belong in the exposure presets), Selective Color, and Silhouette. All operate in movie capture as well as still.
