description: "Plan an animated product video end-to-end: pick the video type, define the animation style and pacing, write a beat-by-beat shot list, and produce ready-to-run keyframe prompts. Use whenever the user wants a product video, product animation, launch video, promo or ad video, animated product reveal, 360 spin, feature showcase, or 'a short video for my product' — even if they only say 'I need a video for the launch' or 'make my product look good in motion'. Also use to storyboard a video another tool will render. Produces a Product Video Production Spec: concept, beat sheet with timings and transitions, keyframe prompt list for fal-ai/nano-banana-pro, and audio/CTA direction."

# Product Video

Turn a product and a goal into a complete **Product Video Production Spec** — one chosen video concept, a beat-by-beat shot list with timings, an animation and pacing plan, and generation-ready keyframe prompts. The governing principle: **one video communicates one thing.** Every beat either builds toward the single message (the reveal, the benefit, the transformation) or it gets cut. You produce the plan and the keyframes; rendering the motion happens downstream.

## When to use / when not to

- Use for product-centric motion content: reveals, feature showcases, product-in-action, transformations, 360 spins.
- If the video is fronted by a person (presenter, testimonial, UGC) → use `skills/creative/talking-head`.
- If the video will be rendered programmatically in Remotion (UI demos, code tutorials, data viz) → use `skills/creative/remotion-script-writer`; you can still run this skill first to define concept and beats, then hand the beat sheet over.
- If the user needs static assets (posts, banners) → `skills/creative/social-graphics`.
- If there is no brand style guide yet and the user cares about brand consistency → run `skills/creative/creative-strategist` first; its style guide feeds this skill.

## Intake

Ask in one tight batch, only what's missing:

1. **Product** — what is it and what's the one thing the video must communicate (new launch? a feature? a benefit? a before/after)?
2. **Where it runs** — TikTok/Reels/Shorts, product page, YouTube pre-roll, trade show loop? (This decides aspect ratio, duration, pacing.)
3. **What the viewer should do after** — the CTA.
4. **Brand style** — is there a `skills/creative/creative-strategist` style guide or existing brand assets to match?

Infer from context instead of asking: aspect ratio from platform, mood from product category, style from any existing brand materials in the project. **Don't stall:** if the product and goal are clear, state your assumptions for the rest ("Assuming Reels, 12s, vertical, energetic — say otherwise") and proceed.

## Workflow

### 1. Choose the video type (decision rule, not a menu)

| If the message is… | Type | Duration | Beat structure |
|---|---|---|---|
| "This exists / it's new" | **Reveal** | 5–15s | hidden/obscured → reveal animation (fade, slide, rotate) → hero shot |
| "It does these 2–4 things" | **Feature Showcase** | 15–30s | feature 1 highlight → feature 2 → feature 3 → full product |
| "Here's the benefit in use" | **In Action** | 10–20s | product in environment → product being used → outcome shown |
| "Look at the change" | **Transformation** | 10–15s | before state → morph → after state |
| "Just show the object" (e-commerce, listings) | **360 Spin** | 5–10s | continuous smooth rotation, clean background |

Commit to one type with a one-line reason. Offer a single backup only if two genuinely fit. Never showcase more than 4 features — cut to the strongest.

### 2. Set pacing from platform

- **Fast** (5–10s, quick snappy cuts): social feeds, ads, anything skippable. Hook in the first 2 seconds.
- **Medium** (10–20s, smooth transitions): product pages, marketing site, email embeds.
- **Slow** (20–30s, deliberate luxurious moves): premium/luxury products, storytelling. Only choose slow if the product's
