  Changing the bit rate dynamically 

 

The Z3-DM8107-SDI2-RPS includes an “Update” button which allows you to change the bit rate 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 bit rate: 

 
 
 
 
 
 
 
 
 
 
 
 

 
 
 

(25)

 

In the CH1 screen, change the bit rate from “8000K” to “2000K” and click the “update” button: 

 
 
 
 
 
 
 
 
 
 
 
 
 

 

(1) Change bit rate to 2000K
