Data Rate

Data rate (or bitrate) is how much data a video consumes for each second of footage, usually expressed in megabits per second. It is the central lever in the quality-versus-size trade-off: a higher data rate preserves more detail and motion fidelity but produces bigger files and needs more bandwidth to stream, while a lower rate saves space at the risk of compression artifacts. Editors manage data rate at export, choosing constant or variable bitrate and target values to match the platform, whether a lightweight client proxy or a high-bitrate master. They also watch source data rates to gauge footage quality and to ensure storage and playback systems can keep up. Resolution, frame rate, codec efficiency, and scene complexity all interact with data rate to determine the final result.
