Dear Christopher,
thank you for that hint. It will definitely make the video better! I'll try to run it later.
As a matter of fact, I first wanted to make a video in which the view point changes and not only rotates around the planet but also closes in and moves away again. It would be nice to approach the trajectories of the planes and "fly through beneath them". Some time ago I saw a video on this website (but not the Community) where they explained how to make the "camera" move exactly as one wants.
Cheers,
Marco
