combined with the “Video quality” to optimize bandwidth utilization and video quality.
Choose “Constant bit rate” If the user wants to fix the bandwidth utilization
regardless of the video quality, choose “Fixed quality” and select the desired
bandwidth. The video quality may be poor due to the sending of maximal frame rate
within the limited bandwidth when images are moving rapidly. Consequently, to ensure
detailed video quality (quantization rate) regardless of the network, it will utilize more
bandwidth to send the maximal frames when images change drastically.
In JPEG mode, user can set “Maximum frame rate” and “Video quality” to adjust
the video performance.
