Editing & Post-Production
Lower third
Also called: name strap, chyron, name tag
A lower third does the introducing so the presenter does not have to. Name, job title, sometimes a handle, sitting in the bottom area of the picture where it will not cover a face. The name comes from where it sits.
Keep it inside the title-safe area so no player crops it, and lift it clear of the bottom edge, where the progress bar and the Shorts interface both live. On vertical video the usable strip is much narrower than it looks on a desktop monitor.
