I read about how to replace a greenscreen with another full screen background but how can i do that in my situation? I have a greenscreen on a tv and im trying to put another video in place of the greenscreen, but the camera is also moving. I was able to make the green transparent so the layer that the movie i want to put into the tv is visible, but when the camera moves, that back layer is also moving off the edge of the tv. Is there some kind of tracking option to make it follow the greenscreen i have on the tv so i dont have to do it manually?

The feature you're after is called motion tracking or match movement.

Chromanator does not support motion tracking, though, so you'd have to do it manually with keyframes.

There are some free 3D motion tracking tools around (google for 'Icarus Motion Tracker' and 'Voodoo Camera Tracker') but you'd then need to import the motion tracking data into a 3D animation program (Blender is free/open source).

Unless you've used a 3D animation program before, it may be easier for you to manually track it in Chromanator.
