Changing the Bitrate Dynamically

The SBE264-DVR-13 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.

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