We are testing vmix to generate characters on our church's live. However, we capture the fullscreen output and we remove the green screen by chroma key, remaining just the titles. But, this way, the chorma don't get that good.
Does someone know a way to use alpha channel by HDMI cable, for vmix just send iamgens and remove the "black" part. We use a capture board. Thanks

NDI supoorts alpha, HDMI or SDI don't. Unless you are doing iMag, why aren't you switching the whole show in VMix?
