The movies we usually watch are only 24 frames per second? Why can some mobile phones shoot more than 60 frames?

In fact, the human eye can recognize 72 frames per second at most. The reason why 24 frames of movies are smooth is that the exposure time of each frame in the movie camera is a quarter of a second, and there is motion blur. However, cell phone shooting is not. In this way, when outdoors during the day, the exposure time is one thousandth of a second, and there is no motion blur. If you still shoot at 24 frames per second, you will feel unsmooth. The only way is to increase the frame rate.
