Changing the Bitrate Dynamically

The Z3-SBE264-25 includes an “update” button which allows you to change the bitrate without stopping
and restarting the encoder.

In VLC, click on “Tools” and select “Codec Information”. This brings up a window with four tabs.

(25)

Select the “Statistics” tab. In this tab, you can see the current video+audio bitrate:
