Moving the slider all the way to the left displays the beginning frame (Cut-in point), and dragging the slider all the way to the right displays the last frame of the animation (Cut-out point). The Current Time field updates to show your new position in the animation.
· The Time Interval display expands or compresses all of the timelines in the Project window, so you can view several seconds at a time, or only one or two seconds. Moving the arrow to the left compresses the timeline, and moving it to the right stretches the timeline out to show only one or two seconds.
· The Cut-in point marks the position on the timeline where you want the rendered animation to begin. There can be animation scripted before this point, but portions of the animation that occur before the Cut-in point do not render.
