Hello,
I am having problems getting more than the first input on my Decklink Duo 2 to show in vmix.

The Decklink Duo 2 is installed in a PC running Windows 10 / vmix 18 / drivers are version "Desktop Video 10.8.4".

I have set up all the Decklink BNCs to be inputs using the BMD set-up utility, which results in the input connectors being in the order 1-3-2-4, which I believe is for historical reasons.

When I connect a 720p50 SDI camera to each input in turn I can see the video using BMDs "Desktop Media Express" utility and the BMD set-up utility shows 720p50 against the input.

However when I set-up 4 inputs in vmix connected to:
Decklink SDI (1)1
Decklink SDI (2)2
Decklink SDI (3)3
Decklink SDI (4)4

Only the input 1 shows any video, inputs 2-4 remain blank.

Any suggestions?
Thanks, Mark Leman

Well I think I have solved this. As usual after several days of testing/research/googling/reading forums I eventually ask a question and then find the answer just after :-)

It came down to un-ticking the "Audio Enabled" setting.

My cameras are "Marshall CV150-CS" and don't have audio. For some reason I un-ticked the box when I created the first input which worked. But later, when I created inputs 2-4 I did not.

Hope this helps someone else in the future.

Regards, Mark Leman

We use Sony BRC700 camera's with vMix trough decklink duo 2 and quad 2 cards, and they work with the box ticked or not while they do not send audio.

It doesn't matter of course because you do not need audio from camera's that don't send it, but it is strange it is a problem in your setup and not with ours.
