Making your animation unfold slower is easy! Simply go to the frames per second slider (fps) under the image on the left side of your screen.

To make the frames go by slower, drag the slider to the left. This will give you fewer frames per second and thus make the frames last longer on the screen.

Remember that if your animation is going too slowly, you can do the opposite. Slide the fps slider to the right. This will give you more frames per second and thus faster motion.
