To Configure the Hardware Channels
The number of hardware channels on your server depends on the configuration you purchased.
- 
            Launch the Tria Config application.
            
You may be prompted to allow the program to make changes on the computer, click Yes.
 - 
            Click the Channels tab.
            

 - Select the video processing mode and how you want the channels grouped.
 - 
            Select the default alpha (key) output that is used on a video plus key channel transport when no alpha channel is present in the clip or no clip is loaded.
            
- Output BLACK on key output — the key (alpha) channel outputs a full frame of internally generated black.
 - Output WHITE on key output — the key (alpha) channel outputs a full frame of internally generated white. Use this selection if the output is going to a switcher as an auto-select key. The full-frame white alpha will force the entire video image onscreen.
 
 - Click Apply.
