How to stretch the text filter background?

New user here. I’d think this would be implemented since it seems like a basic feature.

Text needs to obviously contrast well from its background in order to be legible. Shotcut does have a background feature for text, but it only stays behind the text and doesn’t fill the video vertically/horizontally like a banner.

Is there a way to just stretch the background color behind text?

I basically want to stretch that slightly transparent background all the way horizontally to fill the text on the left/right.

Have you tried using spaces before and after the text?

Hey Steve,

Yeah, I have tried adding spaces before and after. It works but it isn’t very practical. Was hoping for a real method that automatically takes care of it.

Is there not an option?
