Capture Card Debugging

A useful troubleshooting tool to investigate video/audio capture problems is to access the card directly from the card’s application suite. This enables you to access the capture card without using MIP.

BlackMagic

To verify proper operation connect the video source to the capture card. Launch BlackMagic Media Express and click on the <Log and Capture> tab. Assuming everything is working correctly, the source will appear in the Media Express preview pane.
