If the Max Bitrate is “Unlimited”, then the Bitrate selection box
will appear that defines the bit rate level.
When Max Bitrate is “Unlimited”, the user can define the
AVERAGE bit rate. For example, if the Bitrate is 2M, then
occasionally, the actual bit rate may go below or beyond 2M, but
in the long run, the average bit rate will be very close to 2M.
This mode allows the most accurate storage estimations,
however, while planning the bandwidth, please consider the
occasional peaks of bit rate.
The user can define the quality with the numeric scale from 1 to
100. The default MJPEG quality is 60. The higher is the quality
level, the more bit rate the camera will use to achieve the target
quality. However, note that local Live View cannot display
streams other than H.264.
