Thanks, that was simple
I still wish it was more in the way of creating path in spline modeler and forcing camera to be consrained to it so you actually can create circle itself (and use PointAt modifier or others as well), but it will do, thanks again Danilo, now I can finally animate my watch I made recently
There is also no need to explain how it works, I understand it perfectly now, I typed the rotation values manualy for all 4 positions of the camera just before recording it...
