Yes, the biggest downside is losing the multi cam preview. However my livestreams are often funerals or weddings, and I have control of the cameras, so I don’t need the preview so much. I just need my audio to work, lol.
I bet there is a third option, which is bringing the audio in separately from the ATEM. It just depends on how you’re managing your audio. I have my audio coming in via a mixer before it hits the ATEM, so I can send my audio to both my ATEM, my cameras and into my computer all separately. So this may be an option. I just haven’t explored it.
Okay, so the video capture cards I’ve used are the two following (these are Canadian so you’ll have to find your own equivalent):
Cheap amazon $25 card (I have three and they have never failed me, however they are cheap so anythings possible) https://www.amazon.ca/gp/product/B087C3NG9W/
And a more decent card that I use most often:
And my never fail most expensive card:
Using the cheap $25 card might be a decent way to test this.
But the free next test might be to pull audio into the computer via a second method. This might bring up audio sync challenges, I’m not entirely sure. I have something like this:
Let us know if you have any success?
