Lower-third solid bar possible for livestream?

Hello - I poked around and didn't see this in the posts - my apologies if I somehow missed it.

We just purchased an ATEM Mini Pro and I would like to send lyrics over in lower-thirds. We were already doing it with our Roland switcher but the Roland wasn't made for it and we have struggled FOR MONTHS getting it to work.'

We currently have a third screen we're sending to - it's set up to push the lyrics to the lower-third but it's on a solid black background and we're using luma keying to remove the background.

I would LOVE to go green on the slide and drop a black bar into the lower-third that would sit below the text.

When this works on our stream, we run into trouble when the lyrics get placed over anything light or white coming through the camera feed.

Is there a way to do what I'm asking for?

You can create a lower-third template with a "line background"

In the screen configuration settings, set your livestream screen to solid background color: green with a foreground template override to the lower third template you created

THANK YOU! This was very helpful!

We overlay the lyrics onto a video stream. We use a luma key, which works very well. To enhance the clarity of the words, I have adjusted the clip setting in the luma parameters to allow the black background to come through as a slightly dark, semi-transparent background.
