I am creating a video (with After Effects) using a green screen (to cut myself out of the scene) and want to put a business type window pane between myself and my background video. The idea is for it to seem like I'm in an office. What I need is a photograph that already has the background cut out of it with the window area being transparent. Anyone know of a website that sells such graphics?
think about what you are describing and you will realize any transparent window pane will have some kind of background. if you photograph a window so you have the same exposure on both sides so it looks completely transparent you will see what is on the other side.
What you want is a window pane with either a black or white background or as mentioned just a photograph of any suitable window with the right details.
then just mask as suggested .
