link to image doesn't work

you can do this with two masks, input 1 & 2, and a virtual input, as in the example.
the mask is a simple png file with black as transparant and white as visible.

In your live input 1, in the example rasen.jpg, you go to settings, colour key and in the bottom you see Key/Fill Input, there you select the first mask, 1.jpg
In your live input 2, in the example bilder(3).jpg you do the same with the second mask, 2.jpg
create a virtual input from your live input 1
go to the virtual input 1, settings, multiview, on 1 select the live input 2, on 2 select your graphics

thats it.
