smooth camera movement


I’m really a newbe in Animate, so maybe I’m asking something stupid. I’m using the multiplane-mode to create a 3D feeling with 2D elements. It’s for the leader of a tv-series and I pan and travel through a series of layers (made in photoshop).
I have the feeling that the camera movement could be smoother. I’m not talking about the movement itself (that’s fluent enough) but it’s as if there is a slight stutter in the whole of the movement. As if the frames a doubled.

Please let me know if there is a solution,

Is the slight stutter when running it in Animate or when you export it to a movie file?
