Newbie question: 1st movie - export playback not smooth

Hello all,
This is my first try at the free version of Davinci Resolve. I normally use iMovie. I absolutely love the controls and workflow of DR. But my first try turns out to be disappointing. It must be my bad, I don't have much experience in video editing, though I did a lot of home video editing in iMovie.
So the problem is that when I export the project (using "Quick Export"), shots with panning are not smooth.
I tried two Macs: a new M1 MacBook Air and an old 2013 MacBook Pro 15" retina. Both show the exact same behaviour.
Could this be a fps issue?
Thank you.
Peter
