Audio and video knowledge: the surprising world of frame rate
Frame rate, also often described as frames per second (fps), is a term used to describe how many still frames we see in one second. As a filmmaker, this will be one of the first settings you choose - 24, 25, 30. 24fps is generally considered the standard for "cinematic" frame rates. North America accepts 30fps broadcasts, and the European broadcast standard is 25fps.
