5.9 Changing the Bitrate Dynamically
The Z3-DM8169-L1-RPS includes an “update” button which allows you to change the bitrate without
stopping and restarting the encoder. To use it, do the following steps:
(24) 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 (8Mbps shown in
this example):
(25) In the CH1 screen, change the bitrate (in this example, the bitrate is changed from “8000K” to
“2000K”) and click the “update” button.
(26) You should see the quality of the picture in VLC change. You should also observe the video bitrate
drop:
