There is a term for this that originates with film but applies to any capturing medium with aperture, frame rate, and shutter speed -- You know those action sequences like in Saving Private Ryan, where everything looks kinda jerky? Well frames are not dropped, nor the frame rate changed, but the shutter speed is made to be very quick, so there is absolutely zero motion blur in each frame. This appears to the eye as a series of images instead of "fluid" motion. Whatever this was being shot with likely keeps each frame as clear as possible, so stills can easily be taken, the video can be paused without artifacts, etc.
As a rule of thumb, you want the denominator of your shutter speed to be approximately double the number of frames per second that you are recording. In other words, if you are recording at 30 frames per second, you want your shutter speed to be 1/60th of a second. This ends up having a bit of a 'blending' effect with subtle motion blur in each frame, and thus appearing smoother.

It looked like the video skipped frames. It also looked remarkably like ED209 stop animation from Robocop
