Same thing wih shutterspeed (but in "reverse"): The slower the shutterspeed, the stronger the jello-effect. So when shooting with high shutterspeeds you'll notice less rolling-shutter effects. The problem here is that with higher shutterspeeds you might get strobing motion because of the lack of motion-blur.
You shurely know the rule of thumb: Shutterspeed = 2 x fps
With that, you'll get the "normal" amount of motion-blur.
