Hi,
I make a lot of programs with opus using a second screen to put over video.
Now i do that by making the background Green or Chroma key blue. Most of the time it works fine.
Problem can be when the overlay graphic has very thin lines. Some keyers show a small bit of Green or Blue.

A transparant background (alpha channel) would be great.
I tried to turn off the background color from the second screen but then the graphics appear over the desktop.

Kind Regards,
Ad

Hi Ad,

I'm afraid I don't quite understand what you're trying to do.

Can you upload an example somewhere?
