What problem does it solve? Short vertical videos lose viewers in the first two seconds when scripts lack a structured hook, confirmation, and payoff. This Skill turns a raw idea or weak draft into a shootable, timestamped beat sheet built on the retention-gate model, so every second of the video has a defined line, on-screen text, and asset direction. ## Core Features & Use Cases - Retention-gate beat sheets: Produces timestamped rows across the 0-2s hook, 2-5s confirmation, 5-15s payoff, and loop-or-CTA beats, each with spoken lines, on-screen text for muted viewing, and asset keywords. - Multi-platform 9:16 params: Adapts one concept across TikTok, Instagram Reels, YouTube Shorts, 抖音, and 微信视频号 with per-platform format-param rows citing dated norm cards or labeled as Estimated. - Hook options and compliance: Generates 2-3 hook variants from named hook families and adds an AI-content disclosure line by default for realistic synthetic media, marking unverified product claims as [needs source]. - Use Case: A creator pastes a draft Shorts script where viewers drop off at 2 seconds; the Skill rewrites the hook and confirmation beats, supplies on-screen text, and outputs a ready-to-shoot package for TikTok and Reels. ## Quick Start Script a 30-second version of my product demo idea for TikTok and Reels with the goal of saves, including on-screen text and an AI-content disclosure line.
