Develop a creative blueprint for [ProductLine] by [CompanyName] aimed at [Region]. Define message map (problem, proof, product, promo), 3 hook variants, 2 CTA variants, and platform-specific specs for Shorts vs. In-Stream. Propose a test design (MVT): hooks × CTAs × length (6s/15s/30s), with minimum impression volumes. Provide creative QA checklist (captions, safe areas, brand cues in first 3 seconds, end cards).
Output:
A storyboard grid (Markdown) with frames, VO/text overlays, and CTA.
A test plan table: Variant, Hypothesis, Sample Size, Stop/Scale Criteria, KPI ([PrimaryMetric]), Secondary KPIs (VTR, CPV, CVR).
A naming convention schema for assets.
Placeholders: [CompanyName], [ProductLine], [Region], [PrimaryMetric], [CreativeCount], [Timeframe].
