Bitrate or Bit Rate is the average number of bits that one second of video or audio data will consume. Higher bitrate means bigger file size and generally better video or audio quality while lower bitrate means lower file size but worse video or audio quality.

The bit rate is quantified using the bits per second (bps) unit, often in conjunction with an SI prefix such as kilo- (kbps) or mega- (mbps).
