In a virtual studio you can present a "green screen" presenter in a virtual 3D background.
Now you can setup the input sources.
- Click on setup
- Select a layer and assign an input.
- Go back to Camera
When you click on one of the tiny preview scenes the studio will zoom (in/out) to this scenario.
You can set the pan/tilt/zoom speed with the F(ast), M(edium), S(low) and C(ustom) icons.
