compositing in Express

Hi In Express I can now use my own backround jpgs from my computer which is great… But I can still see the backround through my foreground figures even in advanced setting Help !

Are you using a green screen / evenly lit colour? Key to chroma is constant colour background which the computer can recognise and isn’t close to anything on your figures (including reflections). Concentrate on getting the background right. Remember too that the camera position / zoom should remain fixed and characters should move through shot when using compositing - else you’ll get some very odd perspective shots.
