I wish to remove the background of these videos: https://skydrive.live.com/redir?resid=117AB4E465BB25B0!25610&authkey=!AFwzaPNg8TirZQ8

However, sometimes the camera moves up and other things can be seen. How can I remove that too?

You can use masks to isolate your objects from the background. These masks can be animated with keyframes or attached to a tracker to stay on the objects. But it is quite cumbersome.

    $\begingroup$ That depends. To be effective a green screen has to be lit evenly. And ideally have a distance to the foreground objects. Otherwise you have a lot of green reflections on the foreground. It is always work to isolate objects :) $\endgroup$
