Smooth out an object/subject motion

I took a video at 60fps of a piece of art rotating on a lazy susan base. The lazy susan is not automated though so I was rotating it by hand. I tried hard to make the roatation consistent and smooth but unsurprsingly I was unable to make it super smooth. If there a way in Pereiemer or even After effects that can be used to clean up the roatation motion so that it is smooth for the whole 360 degress roation? All I seem to be able to find is warp stabilzer but that does not work as far as my tests show as its really meant for steading the video clip. My camera was on a tripod so the footage is still, its just the motion of the object as it rotates that is not consiostent and smooth. My final piece will be 30fps so I was hoping the fps difference would enable an "effect" to have enought to work with

Any advice welcomed.
