Good morning and thank you very much in advance for the help they can dispense me:
I have a Blackmagic DeckLink Extreme card and am using VMix to generate graphics and characters and send the signal to a mobile television, the question is: how can I tell the blackmagic what is the key and fill that is generating the VMix to recognize the switchera video and chroma can be generated without having to do it in the video console, I'm sending the video via SDI using both outputs more reference, I understand that I should use the LiveKey but so far have failed to do so, grateful the help they can lend
