Rate Control
Choose a bit rate control to manage your bandwidth usage.
Variable Bit Rate (VBR): VBR keeps the video stream quality as constant as possible by varying
bit rate. This mode ensures high quality image for motion scene and is often selected when image
quality demands priority. However, this mode requires more bandwidth in order to vary the bit
rate.
Constant Bit Rate (CBR): CBR maintains a specic and constant bit rate by varying the stream
quality. With CBR, streaming is smooth and network throughput is stable for any scene. This
mode is typically used with a limited bandwidth environment.
