Animation too bumpy!

I am not very savy at animations. My last one is too bumpy and pauses too much between some scenes.
Is there a way to control this other than the frame rate option?

Window>Model Info>Animation will allow you to adjust the speed of the transition time and delay time. Frame rate will dictate the “choppyness” of playback.

Are you outputting the animation and watching the output video? Watching the animation by playing the scenes within SketchUp is often choppy as sketchup struggles to render fast enough. The output video will be smooth provided your GPU/CPU is up to the task of playing it.
