Did you enabled the plugin?
I know this is a rather old post but, it just deals with what Im struggling with.
Im using a Corvid 44 on Unreal 4.27.
Set to output fill on SDI 3 and key on 4. Both outputs work but the key is…a grayscaled version of the fill, and not a black and white key. My objects are solid, so Im not really sure what could be going wrong.
Im also getting this warning:
LogAjaMedia: Warning: PingPong: No frames are available for channel 3 on device Corvid44 - 0.
And cant find info on that.
And just found out with UE5 it just works. Great
