## Current revision

Frame rate, or Frame frequency, is the measurement of the frequency (rate) at which an imaging device produces unique consecutive images called frames.

The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems. Frame rate is most often expressed in frames per second (FPS) and in progressive-scan monitors as hertz (Hz).

There have always been three main frame rates:

• 24 frames per second used for Cinema and projection
• 25 frames per second for European television
• 30 frames per second for US and Japanese television

Due to some technical problems when the American 525-line colour television system was developed, most 525-line television has a frame rate of 29.97 frames per second.
