I assume you’ve created the titles in a text layer already. You have to treat the titles as an object and manipulate the position with keyframes. For instance if you want to have a vertical scroll, at the starting point on the timeline, click on the name of the layer and press P to open the position attributes. Change the Y coordinate (the second one - X,Y,Z - it should be defaulted to 360, 270. 0)on the position attribute (depending on how big it is the number will change, but start at -270 and see how it looks) for the layer and enable a keyframe by pressing the clock icon. Go to the time you want the scroll to end on the timeline, and change the Y value to, say, 500 and see how it looks. The layer should move vertically from bottom to top over the course of the time between the two keyframes. Change the Y values to adjust the speed.
I don’t know what you mean by split.
