Here is it possible, to adjust the contrast and brightness using the corresponding sliders. A change of that values is instantaneous visible.
The third slider is for adjusting the animation speed. The values says how much frames per second are visible. Changes of this sliders will also be saved instantaneous, but will not be used until you restart the animation. Which simply means stop the current animation (if there is one) and start a new one.
Be aware! The speed of the animation depends on your hardware. It is possible that rendering a frame takes more time than you want.
