Aja plugin-Corvid 44 issue


I’m having a few issues getting started with the Aja Video I/O plugin and was hoping someone could suggest what I might be doing wrong.
I’m feeding in a 1080i50 signal but am only seeing the default color bars when I drop the Aja video sources into the scene.
I’m using a corvid 44 video card and have set the source format in the project settings/Aja menu to match the 1080i50 signal I’m inputting to the card. In terms of troubleshooting I’ve tried using all the different BNC connectors on the card.

Is there a specific firmware version required? The Aja control centre software updated the card firmware and detects the signal there, so it appears to be working externally of unreal

Many thanks
