Write a short-form video script for TikTok, Instagram Reels, or YouTube Shorts that is built on the hook to retention to payoff structure designed to drive watch-time. It produces a timed script containing a zero to three second hook, retention beats with on-screen text and B-roll cues, a payoff, and a call to action, along with a caption and an on-screen text list. Reach for this skill when you need to script a fifteen to sixty second vertical video rather than a long-form YouTube video. It includes guidance on working from a brief, quality checks, and anti-patterns to avoid slow intros or multiple competing calls to action.
