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.
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?
Are they in different systems or in the same?
