Place the media clip that want to be display as background on Track 1.
Place the media clip with the green screen background on Track 2.
Double click on the clip with the green screen background to open in the PiP Designer.
Select the Chroma Key tab and then Enable chroma key
Click on the eye dropper button on the Chroma Key tab and then select the (green) color in the image or video clip that you want to replace/make transparent.
