Bit Rate
Definition
Bit Rate (or "bitrate") is the amount of data used to represent a second of digital video or audio, measured in bits per second (bps) or megabits per second (Mbps). Higher bit rates generally result in higher image quality but larger file sizes, while lower bit rates result in smaller files but potentially lower quality (more compression artifacts). The appropriate bit rate for a given application depends on the intended use: streaming video typically uses lower bit rates (2–8 Mbps for HD) to reduce bandwidth requirements, while professional production and archiving uses much higher bit rates (50–800 Mbps or more).
Contextual Usage
The post-production supervisor specifies the delivery requirements: "The broadcast master needs to be delivered at a minimum bit rate of 50 Mbps in the XDCAM format. The streaming version should be delivered at 8 Mbps for the 1080p version and 4 Mbps for the 720p version. Please make sure the encoder settings are correct before you start the final export."
