The distinction between super slow motion and slow motion lies in the frame rates. Super slow motion involves shooting above 500fps.
The human can only see a diﬀerence in frame rates when its doubled. Thus consider doubling your frame rates, such as from 50 to 1 00fps, 1 00fps to 200fps, 200fps to 400fps, 400 to 800fps and so forth. In-between frame rates have little eﬀect on visual impression.
