Frage von mariechen004:
Hello s.alle,
I have a question regarding a "zoomfähigen" Green Screen.
And indeed if I myself produce a small clip with green screen, then zooms out so the background is not with. So when I ran for example, with the camera zoom in closer, then the green screen background remains steadfast. So he did not zoom with.
Now my question! Like for eg TV stations realize this, that the background mitzoomt? An example is like this virtual studio of news broadcasts, which are realized by means of green-screen (eg today). When the camera zooms out there, then zooms synonymous with the green screen background.
How do you implement such a thing? Is there maybe, not with the camera zoomed in, but only in the finished camera zoomed image produced?
I myself would like to realize this is not at the moment is synonymous determined more expensive. But the technique would be used to interest me very.
So I hope you can understand my question and look forward to your responses.
Regards
Marie

Keyframes is the keyword. How this works, you'll find everything on the net. Just looking:)

If you only want to zoom into the picture, the effort is not so great. Then you also synonymous zooms the background. Optical effects, such as the decreasing depth of need in the telephoto range you adjust.
Complicate matters on motion (s) of the camera (s) in space. So pans and rides. A great rental studio solution provides www.vr3 (dot) de. The effort is already quite large, but the result is entirely realistic.

Motion tracking is synonymous still such a concept!
Point is tracked and the background reference (to the tracked point is fixed, so to speak there!)
To realize with AE.
