Bitrate measures the number of bits that a codec can transmit over a certain period of time. This can be done over a transmission system, or between two digital systems. Bitrate can be measured in megabits per second (Mbps) or kilobits per second (Kbps).
The higher the number (regardless of the unit of measurement used) of bitrates in a production, the better the final quality obtained on it. If we talk about internet, a high bitrate would mean that the content comes very quickly from the network, improving the experience of the user.
In the audiovisual sector, bitrate is defined as the amount of data stored per every second of playback. If we work with high bitrates, the quality of the audiovisual fragment will also be high.
If the source of the content has a poor quality, the result will also be poor, regardless of how the encoding was performed. It is not convenient to execute a process to obtain decent quality with low bitrates, as it would apply a lot of load on the decoding systems.
