Something about be a rate higher than 24 f.p.s

Is that one reason a higher resolution image or

a high quality slow motion or,

something that I listen and never find - the image could be manipulated to be 3 dimension, with a computer to redefine it

And say why can't we make two cameras film the same scene in the same point with the computer understanding being the same image and have a rate of 48 f.p.s? Rute Bezerra de Menezes Gondim
