Quick definition
A lower third is a graphic overlay in the lower part of a video frame — typically a name, title, or caption — adding context without interrupting the footage.
A lower third is an on-screen graphic placed in the lower area of a video frame, named for the bottom third of the screen it traditionally occupies. Borrowed from broadcast television, it displays supporting information — a speaker’s name and title, a location, a topic label, or a caption — layered over the video without blocking the main subject. Lower thirds can be simple text or animated bars, banners, and boxes with logos and motion. Their job is to give viewers context at a glance while keeping the focus on the footage itself.
On social video, lower thirds do far more than name a speaker. Creators use them to reinforce hooks, label sections, add commentary, brand a clip with a handle or logo, and keep viewers oriented in fast-paced content. Because much social video is watched on mute, on-screen text placed low in the frame carries information that audio would otherwise deliver. Designers also account for platform interface elements — captions, like buttons, and progress bars often crowd the bottom of vertical video — so lower thirds are frequently nudged higher or kept clear of the edges to stay readable.
A clean, consistent lower-third style is a low-effort branding win: matching fonts, colours, and placement across videos makes clips instantly recognisable as yours. The practical caution for vertical formats is safe zones — platform UI overlays can cover the very bottom of the frame, so critical text belongs above that clutter. Used well, lower thirds add professionalism and clarity; used carelessly, they compete with captions and interface elements for the same crowded strip of screen.
