Though static titles, graphics, and logos suffice for some projects, many others require titles that move across the screen. Titles that move vertically over the footage are called rolls. Titles that move horizontally are called crawls.
The length of the title clip in a Timeline panel determines the speed of the roll or crawl. The more you increase the title clip length, the slower the movement.
Create the text and graphic objects for the rolling or crawling title. Use the Titler panel scroll bar to view offscreen areas of the title. When the title is added to the sequence, the offscreen areas roll or crawl into view.
For rolling credits, create a long text box using the Area Type tool, and use alignment, tabs, and leading to adjust the formatting.
You can specify a direction for crawling titles only.
