Keying in a PIP window

Studio Operators Content Creation Composer Node System 3D Scene Editing Video Playback Virtual Camera

 

Hi guys,


Can we key out the green background of a video (or a video input) played/streamed in a Virtual Screen.?

I've tried the different nodes Chroma/Luma, but no luck.

I would like to add a BG to a subject filmed onto a green screen which I am also using as a billboard.


Any advice ?

Thanks
