Bit rate refers to the number of bits that are conveyed or processed per unit of time, usually expressed in bits per second (bps) . Bit rate is used in telecommunications and computing to measure the amount of data being transferred or processed within a certain amount of time. Bit rate is often measured in conjunction with an SI prefix such as kilo, mega, giga, or tera. Bit rate is a fundamental measurement of video and audio quality, and it affects the size and quality of the video or audio file. Bit rate is distinct from other measurements of video quality such as frame rate, resolution, or video format. Bit rate is usually measured in bits per second (bps), while audio files are typically measured in kilobits per second (kbps) . Bit rate encoding can vary depending on the type of footage, and finding the optimal bit rate is a balancing act between file size and quality. A higher bit rate results in better quality but also larger file sizes, which can cause buffering issues.
