The parameter “Frame Rate Divider” can also be updated dynamically using the “update”
button. All other parameters require a stop and then start to change.

Adjusting the UDP TS Rate
The Z3-MVPR-02 includes a parameter to adjust the TS rate independent of the video bitrate. This can
be found just below “PMT PID” when “UDP” is selected as the output format.
Normally, this value is set to 25% to 33% above the sum of the video and audio bitrate. For example,
the default value out of the factory is a value of 10Mbps, corresponding to 8Mbps for the video.
There are times, however, when it is desirable to make this value higher. For example, if the encoder
bitrate is very low (below 1Mbps), it is advisable to allow more leeway in the event there are some
challenging scenes to encode. An example follows:

Return to the “CH1” tab. In this tab, click “stop”. Then change “Video Resolution” to
“720x480”, “Video Bitrate” to “512K”, and “Output Format” to “UDP” (steps 1-4 in the figure
below):
