Rate Control :
Defines the rate control method of this profile. There are four options: Constant Bit Rate
(CBR), Variable Bit Rate (VBR), Enhanced Constant Bit Rate (ECBR), and Enhanced
Variable Bit Rate (EVBR). For CBR, the video bit rate is between low to high bandwidth
based on different resolutions. User can set the desired bit rate to match the limitation of
bandwidth. For VBR, user should choose the quality level to set the video quality rather
than bit rate. The quality level is between 1 and 100. The higher value can reach the better
quality but of course will consume higher bandwidth.
„
Max Frame Rate
Defines the targeted frame rate of this profile. For example, set the frame rate to 15 fps,
then the image will be updated for 15 frames per second as possible. User need to set
reasonable max frame rate versus video quality under the limited bandwidth.
