Multiple Blackmagic Mini Recorder 4K in VirtualDub?

[optimus786]

I have two blackmagic mini recorder 4k's
both are showing up, and both will work in other software like blackmagic media express.
The issue I'm having is in virtualadub there is only one instance of decklink video capture and audio capture, there is 2 blackmagic wdm instances but the audio isn't usable that way.

Anyone know how to get it to acknowledge so it shows Decklink Video Capture and Decklink Video Capture #2 ?

Blackmagic devices don't allow audio to be monitored via the OS audio sound card, You would need an external audio monitor, headphones or powered speakers, It is never a good idea to monitor audio via the system anyway, it leads to a lot of problems.

I am running it with analog to sdi to the capture cards.
I can run 2 instances of media express or 1 virtual Dub 1 media express and it will capture the audio fine, although I have to normalize the audio levels later because it's low.

So I can make it work, just not both in virtualdub.

This is just not suggested in any way.

#1 - Trying to capture more than one video per system never works. The system cannot share resources like this.
#2 - Blackmagic cards have known limitations, issues, and errors.

I would never do that.
