Live Rendering: 360-video rotates the model far in the horizon

Hi, I've been doing 360-videos and some of them seem to generate just as wanted, but some tend to force the model too far away from the viewpoint. I seem to find no logic in this. I've tried zoom and dolly-zoom. I've tried to manipulate the origin. I've tried to alter the distance to target, but with no success. How do you get to generate a video that is exactly what you see in the thumbnail windows?
