Old films were called flicks because they were below 24 FPS and flickered as a result . This won ' t happen on your computer monitor unless your monitor itself is below 24 Hz . Persistence of vision is why waving your hand in front of your face may show a trail or moving your cursor around on your monitor will show multiple cursors even though it ' s only ever in one spottake a screenshot or record a video and watch framebyframe . It ' s also why work .
