The human eye can perceive anywhere from 480 fps to 4000 fps , and see it as looking completely realistic or immersive naturally. While 120 fps looks 'realistic', the stroboscopic look can still be seen, which also happens on 60 Hz monitors playing 60 fps video and sometimes excessive motion blur, depending on the camera and shutter speed that was used when the video was recorded. Otherwise, videos over 200 fps are more preferred, since they look more fluid and realistic naturally or by simply changing the shutter speed with an ND filter at frame rates between 50 fps and 120 fps..
