What is the role of text overlays in videos?

Text overlays in videos primarily serve the purpose of explaining or enhancing the video content. By adding text directly onto the video, creators can emphasize key points, provide context, or clarify information that might not be fully conveyed through visuals or audio alone. This helps the audience better understand the message being communicated, especially when complex topics or specific details are involved.

While text overlays can be an element of visual effects, this is not their primary function; instead, their main goal is to make the content more accessible and informative. The identification of file formats and the use of subtitles both serve different specific purposes that do not align with the overarching role of text overlays in facilitating comprehension of video material.
