Question: what is the difference between data rate and total bitrate?
Answer: The term data rate is synonymous with bit rate. ... DV clips, for example, have a data rate of 30 megabits per second (Mbps), whereas a broadband-quality Web video clip can have a data rate of 500 to 1000 Kbps. The total bit rate of a video clip is divided between the video track and the audio track.
