As with the regular titles, click “Change the title animation” to change how your end credits are displayed. You will see the animations listed under “Credits” first, although you can apply the animations listed under “Title, One Line” and “Title, Two Lines” if you want. However, this only animates the headline and ignores all the other text.
The default animation for end credits is “Scroll Up, Stacked.” This is fairly traditional – most feature films have end credits like this. But you can get adventurous if you want with options like “Credits: Video Left” which make your credits look like end credits from a TV show.
