I could not find anywhere a way to choose movie settings to shot at 60 fps or 90 fps instead of 30 fps to produce slow motion movies with the Nikon D800. Does that man that it is definitely impossible to do so with this camera ?
The answer is, 60FPS comes standard on say an A99 Sony at 1080P however on the D800 that frame rate is available at 720P, this, for some reason (likely) is because the vast majority of video shot is used for DVD, where 720 is the spec and where 30 (60) FPS is also the less blurry standard.
It is also where the footage shot at 1080i/p ends up being down scaled into 720. BluRay is a different matter.
Not sure about the newer Nikons however, as a stills and a video shooter, I'm not giving up this camera anytime soon.
In discussing the "why" with my associate a few days ago (a DP who has the A99 but has open envy for my D800 on stills) he said (paraphrased) why are you complaining, you have a full frame sensor and can shoot a film at 720? He is also addicted to 60FPS for slow motion uses.
Some people who have say, a D7000, will use the full frame D800 for wide, and long shots, then use that larger FOV in post to rack focus blending with the cropped footage of the D7000.
So go for it, no one is going to know because the 2MP files, will be pretty darn crisp from the D800. Mixing 720/1080 clips is done all the time.
That setting is in the last menu on the green camera icon: Movie Settings, under Frame Size/frame rate.

I believe the D7100 shoots at 60 FPS and at 1080P so one would surmise that if Nikon were Canon, a firmware would, might solve the problem, but Nikon seems less intent on existing technology and would rather drive new products.
The 36MP sensor resolving at 720, yes, usable but not optimal.
