A reference campaign claimed jewelry is the hardest category for AI because the product drifts shot to shot. So we took the hardest brand and the same brief — and shipped the three ads that matter, with the product locked and evaluated, every brand word legible, and a price tag that holds: ~$24 per brand, repeatable for any SKU.
Studio → macro → 3D turn → on-model → boutique → the blue box. One locked key across all six. The wordmark, the material line, and the CTA are a deterministic graphics layer — pixel-perfect and correct, never AI-generated. That is exactly the thing raw AI-video tools admit they get wrong.
We start from the actual product photo as the locked reference, then place that exact key into each world with edit-not-regenerate — never re-rolled. Before a single frame of video, we render this grid and verify the key is identical to the real piece: the same openwork round bow, the same radiating diamond spokes around a central cushion-cut yellow diamond, the same fine pavé outer ring, and the same slender diamond-set shaft with its key teeth — at its true delicate 2″ scale when worn. It matches.

Every language is its own cut, sized so the voice and music fully resolve — no clip ends on an abrupt, raw cut.
| What matters | Raw AI-video tool (the reference) | Storyboard |
|---|---|---|
| Product consistency | best-effort via reference images; drifts | locked asset + a consistency GATE — 6/6 identical |
| Brand text · price · logo | AI-generated — their admitted weak spot | deterministic overlay — legible & correct |
| Global reach | one language | localized, voiced, per market |
| Endings | often a raw cut | voice + music resolve; brand-card close |
| Rights | varies | licensed score (Sonilo), no scraped assets |
| Cost | subscription seat | ~$24 per brand of compute |
| Repeatable at scale | a hand-made demo | a playbook + API — swap photo + brand kit |
This entire set is a parameterized pipeline. Point it at a new product photo and brand kit, and it runs the same loop — lock, place, evaluate consistency, animate, overlay legible text, score, resolve, deliver — with per-asset spend caps and a cost report.
