I have the same feeling too. The video does look choppy more or less 
after changing FPS, especially reducing FPS a little bit (e.g. 25fps to 
24fps).
I think this is somehow unavoidable without rendering all frames again 
which will bring much computation. As the interval of frames changes, 
the content of frames must be changed in order to look really smooth.
