Track Camera to a fixed object after tracking video

Hi,

Is there a way to track a video and mark an object (rectangle) in it such that if you place another camera in the scene pointing towards this object, the object will appear stationary to the new camera. My purpose of achieving this is to capture the screen of digital devices like Smartphone, Camera view finders, monitor, etc in a video and use them in tutorials. The new video should only have the screen of the digital device.

You can use a movie as a Material Texture for an object, like a plane - then the movie will play on that surface as you run the automation.

Cheers, Clock.
