Frame Rate
Rate – The video frame
rate is adjustable based on network
conditions. Increasing the frame rate will
increase the amount of data significantly
therefore consuming more bandwidth . . . . Video
will be impaired due to packet loss when
there is insufficient bandwidth.

Control – Variable Bit rate (VBR)
and Constant Bit Rate (CBR).
Variable Bit Rate - If VBR is selected, the codec varies the amount of output data per time
segment. VBR produces a better quality-to-space ratio. The bits available are used to enable
more flexibly and encode sound or video data more accurately,with fewer bits used in less
demanding passages and more bits used in difficult-to-encode passages.
Constant Bit Rate - If CBR is selected, the codec's output data is constant regardless of the
input data. The output bit rate is defined in "Bit rate". CBR is useful for streaming multimedia
content on limited capacity channels. It is easier to calculate required bandwidth as well as
the required storage space using CBR.
