What does a roll title do in video editing?

A roll title is a type of text effect used in video editing where the text moves vertically over the footage. This motion often occurs from the bottom of the screen to the top or vice versa, creating a smooth and engaging way to present credits or other information. This technique is commonly seen in films and television credits, where the text rolls up the screen, allowing viewers to read while continuing to see the content behind it. The vertical movement distinguishes roll titles from other forms of on-screen text, such as crawl titles, which typically move horizontally across the screen. Understanding this distinction is crucial for properly utilizing titling effects in Adobe Premiere Pro.
