Frame Rate

The frame rate of any motion picture, whether film or video, defines how often pictures are taken per second. The higher the frame rate, the more accurately you capture moments in time and reduce flicker during playback. To achieve double the perceived frame rate (flicker), film projectors actually double or triple the shutter speed, even though the same frame is repeated two or three times, respectively. This is because a faster flicker creates more convincing motion. Video uses a similar, although more complicated, technique called interlacing. For more information about interlacing, see Scanning Method. For more details about frame rate, see Frame Rate and Timecode.
