Hi Philip,
If you’re getting sound but no video there could be a couple of problems. Either the capture format setting does not match the incoming signal. This is set in Media Express’ preferences in the Project Video Format dropdown box. Please also make sure that the input connection is set correctly in the Blackmagic Control Panel.
This could also be down to the preview in Media Express not rendering correctly. I would suggest making sure that you have the latest graphics card drivers installed from the manufacturer’s website.
If you do continue having problems however, please do contact your regional Blackmagic support team. You can send a support request from the support page for the UltraStudio:
