Lower third
The name-and-title graphic that appears near the bottom of the frame to tell you who is talking.

What it is
Named for where it sits: the bottom third of the frame, clear of the speaker's face and clear of the very bottom edge. Broadcast calls it a chyron, after the company whose character generators put them on TV news. The standard build is two lines, name in a heavier weight and role or handle underneath, often anchored by a rule, bar, or brand shape.
Bring one in the first time a person appears on camera, and again after a long absence. Animate in, hold 4 to 6 seconds (long enough to read it twice), animate out. The exit deserves as much attention as the entrance: graphics that snap off feel cheap, and graphics that never leave clutter the frame.
Gotcha: safe areas and vertical crops. A lower third built for 16:9 gets sliced or buried when the same video is reframed to 9:16, where auto-captions, usernames, and platform buttons all fight for the same bottom third. Keep it inside the title-safe area, and rebuild it for vertical rather than scaling it down.
Ask AI for it
Design an animated lower third for a talking-head interview: two lines of text, name in semibold 32px and role in regular 20px at 60 percent opacity, left-aligned, sitting inside the title-safe area roughly 15 percent up from the bottom edge. Add a 3px accent bar that wipes in from the left over 400ms with an ease-out, with the text sliding up behind a mask and a 60ms stagger between the two lines. Hold 5 seconds, then reverse out. Keep the graphic clear of the subject's shoulders and no wider than half the frame.
