# explainer-video

Walks the agent through the full pipeline: script, storyboard, scene build, narration and caption sync. Useful when one idea has to become a 30–90s video.

## What it does

The skill sets the order of work on an explainer: script first, then storyboard, scene build, narration and caption sync, edit, polish. Voiceover is treated as the spine — visuals illustrate the line being spoken, never lead it. So the words get written and timed before anything is animated. Cutting a sentence is cheaper than cutting a built scene.

Inside you get a script formula with runtime shares (problem, solution, how, payoff), a pacing rule of about 2.3 words per second, and ready scene techniques: diagram nodes revealed with `gsap`, kinetic keywords in CSS, a count-up stat in JavaScript. For the assembled piece it points to Remotion or After Effects. Captions are mandatory — up to two lines, no more than 42 characters each, on screen at least 1.0s, because plenty of plays are muted.

Lock the style system before scene two: one type scale, one color grammar, one easing curve. If an analogy needs its own explanation, it is the wrong one. The skill does not draw or render for you; it keeps the agent on the steps and holds one style across scenes.

## When to use it
- turn a single idea into a 30–90s explainer
- write a script and storyboard for a product video
- sync narration to scene cuts
- add captions for muted playback
- keep one visual style across every scene

## Example prompts
- Make an explainer video about our delivery service, 60 seconds
- Write the script and storyboard for an onboarding video
- Sync the narration with captions and build the scenes

# Explainer Video

Turn one message into a paced, narrated 30–90s short. Run the full pipeline: script → storyboard → scene build → narration/caption sync → edit → polish, with a consistent style system throughout.

## When to use

- Produce a 30–90s product, how-it-works, onboarding, or concept video.
- Go from a raw idea or feature to a script, storyboard, and assembled piece.
- Sync narration to visuals and add captions for muted playback.

## Story structure (decide this first)

An explainer is an argument, not a feature tour. Before any pipeline step, lock the narrative so every later choice serves it.

- **One core idea.** A single sentence the viewer should be able to repeat afterward. If you can't state it in one line, the video has no spine — cut scope until you can. Everything that doesn't serve that idea gets dropped, not shrunk.
- **Script-first.** The VO is the spine; visuals illustrate the line being spoken, never lead it. Write and time the words before you storyboard or animate — it is far cheaper to cut a sentence than a built scene.
- **Earn the "how" with stakes.** Don't jump from problem to mechanism. Make the viewer *feel* the cost of the problem first; that tension is what makes them watch the solution.

The explainer story arc — a beat per stage, in order:

| Stage | Narrative job | What the viewer should think |
|---|---|---|
| Problem | Name the pain in their words | "That's me." |
| Stakes | Show what the pain costs (time, money, risk) | "I need this fixed." |
| Solution | Introduce the product/idea as the fix, in one line | "Oh — that solves it." |
| How it works | The mechanism in 1–3 concrete steps | "I get how it does that." |
| Payoff / CTA | The after-state + one next action | "I want that. I'll do X." |

(The `Script formula` table below maps these stages to runtime shares and word budgets — this section is the *why* and order; that one is the *how long*.)

### Pick one analogy and ride it

Abstract mechanisms land when mapped to something the viewer already knows. Choose a single metaphor and keep it consistent across scenes — switching analogies mid-video resets comprehension.
