What is a Roll title in video editing?

A Roll title is defined as a title that moves vertically over the footage. This type of title is typically used to simulate the effect of scrolling text, commonly seen in credits at the end of films or in news programs, where text rolls from the bottom of the screen to the top.

This movement creates a dynamic visual effect that captures the viewer's attention. Roll titles contrast with static titles, which remain fixed in one position on the screen; static titles do not have any movement, thus not providing the same engagement. Moreover, Roll titles distinctly differ from horizontal movements, where text might slide in from the side. The specific vertical movement of a Roll title is what classifies it and sets it apart, emphasizing its use for displaying lengthy text like credits or announcements in a visually appealing way.
