The video bitrate or data rate is the number of 'bits' conveyed or processed in each frame of your video over time. Here, 'bits' refers to the compressed data in your video frame, and the rate is usually time in seconds. So video bitrate is measured in kilobits or megabits per second (Kbps or Mbps). Higher bitrates often signal higher video quality. But they'll also require more storage and greater bandwidth for playback. Lower bitrates are just the opposite.
