What is a lower third?

A lower third is a graphic overlay that appears in the lower part of a video screen or frame. It typically includes text information such as the name of a person being interviewed, their title or role, and sometimes additional contextual information like a location or date. Lower thirds are often used in news broadcasts, interviews, documentaries, and other types of video production to help identify who is on screen or provide context for the viewer. Lower thirds can also be customized with different colors, fonts, animations, and other design elements to match the overall style of a video or brand.
