I am using a ClonerAlliance Flint D4P. I am trying to use 2 Sony A6000 DLSR cameras for multiple angles. The device connects just fine and is easily recognized in the list of video capture devices. The problem is that it only recognizes one camera. Whichever connects first, occupies both spots in the frame. I am a super novice at this. I could use the expertise of others. Thank you.
