Hi Everyone, first of all say hello to all in this very cooperative forum. Great one!

I've been trying for days to make my decklink duo 2 work full duplex and no luck yet. No problem on getting 2,3 or 4 inputs working but I can't get the card work as output. For what I do (Mostly corporate conferences) I need to configure the card as 2 in 2 out or 3 in 1 out. I have tried every single "Decklink video render" output but nothing. Instead I get the following message:

"The selected external renderer device is in use or does not support the selected format. Please check your external output settings and try again"

Of course I did try different resolutions with every single frame rate and still nothing.

If any of you can help me I will own you one

Thanks!

Cristian

You'll need to use the Blackmagic Video Utility app to change the port routing, then it should work in vMix. The app was installed when you installed the driver.

Second what Tom said. I use this card in a external AKiTiO Thunder2 PCIe Box and use in similar way with 4in or 3 in 1 out etc depending on the need. Needs to be configured in the Blackmagic
Desktop Video Setup application.

Thanks very much for your reply

I did not mention it but I have done all the configuration on the blackmagic desktop video setup. I can get 2,3 or 4 input but no output.
I set it up as following

decklink 1= 1
decklink 2= 3
decklink 3= 2
decklink 4= None

With this I get the error I typed before on vMix

I know this card works for everyone so I'm conscious that I'm doing something wrong but seriously I have tried so many times that I got lost.

If anyone can send me pics of their configuration on the blackmagic software and the external output window on vmix I would appreciate it.

Thanks in advance

Cristian
