Decklink Quad 2 configuration

#1

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.


Casparcg.config - Idiot-advice
#2

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.


#3

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?


#6

Are they in different systems or in the same?
