The main point is motion blur, in motion pictures the normal exposure time is about 1/50 sec, so that moving objects blur, this gives the illusion of motion on the screen. The shots join up. Moving objects look like they are moving without flicker.
1/50 second will result in a lot of shots with too much blur for still use.
If you decrease the exposure time the pictures will be sharper less blur but the motion will stutter.
Photography is quite safe, it is about capturing the moment.
Cinematography is about change. That is why everything about cinematography is about moving the camera, moving the actor in and out of light, explosions, compression and expansion of time.
