For the five Scroll effects, there are also Start and End controls. These determine precisely when the motion effect will begin and when it will end.
For each state, there are two sets of three choices. Which part of the column to target, and where in the viewport it should be applied to.
So, for ‘Start’ options you will find a Top of Element, Middle of Element and Bottom of Element, and for the ‘Hits The’ options, you will find Top of Viewport, Middle of Viewport, and Bottom of Viewport.
The same options are found for the ‘End’ options. In this way, you can control precisely when the effect will being and end.
