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 specific 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.
