Purpose

Produce a 20–35s narrated product demo — a use-flow walkthrough (unbox → load → use → enjoy) where every spoken claim is immediately matched by a proof visual, the pacing follows VO phrase boundaries, and the hero moment is given a deliberate payoff hold. The format maps to the vo-product-demo archetype: vo+music, karaoke-pop captions, VO-paced (not beat-synced) cuts.

Structural spine:

1. Hook (0–15%): One sharp claim-caption or visual pattern-interrupt that answers "who is this for and why."
2. Use-flow body (15–70%): Ordered steps through the product experience — unbox → load → use → enjoy. Every spoken claim has a proof visual within 1.5s of the word.
3. Payoff hold (60–85%): The single longest shot (2–4× the mean shot length) — the product working, the result, the hero moment.
4. Tail (last 15%): Decelerate. A held final frame or a light end card. No burned-in CTA.

Use for: DTC product launches, app or SaaS feature demos, unboxing-style shortform, tutorial/how-to VO ads.

Do not use for: silent feature-flash demos without VO (use create-silent-product-demo); lyrical lifestyle brand essays (use create-broll-narrative-essay); before/after formats (use before-after-video/).
