Where can I find documentation on the decklink configuration commands. I can set up my quad 2 to output key/fill pairs, but I am having trouble getting individual outputs or inputs working.

The Quad 2 and Duo 2 cards need to be configured in BMD‘s control panel applet to the amount and mode of the inputs and outputs. Then Caspar can detect and use the channels.

</div>

here an example of my caspar.config for DUO2 **(only channels section of the XML file)**  
for Quad2 to have 4 channels just double this and renumber the sections device 1 & 2 to 3 & 4  
i have added a connection drawing for the Quad4 card also. connectors for Duo2 are the same, lowest reference, then the 4 outs, instead of 8.  
you can configure the channels **in the Blackmagic Control** as **single** or **fill and key**  
you even can mix these to have 2 channels as fill and key and the rest as single channels.  
**but this is changed in the Blackmagic Control only**

i hope this helps

Thanks, the frontend settings make a lot more sense under that channel layout scheme also.

Hey guys.  
I’m having more or less the same problem with my second card, the first card works, however I can’t play anything off my second. Any suggestions?
