Brag Launch Video

## Tone system

Seven tone presets ship with `/brag`. Each changes scripting energy, pacing, typography personality, and transition style. Presets are defaults, not limits.

Full definitions: [references/tones.md](references/tones.md)

| Tone | Energy | One-liner |
|---|---|---|
| `default` | Playful, clean, postable | The good-vibes default |
| `polished` | Serious, elegant | For projects that are not jokes |
| `yc-parody` | Deadpan startup energy | Fake seriousness applied to absurd projects |
| `chaotic` | Fast, loud, aggressive | Over-the-top and unhinged |
| `deadpan` | Calm, dry, understated | The joke is that nothing is a joke |
| `cinematic` | Dramatic, trailer-scale | Big motion, bigger claims |
| `app-store` | Smooth, feature-card clean | Corporate but not boring |

Always allow a freeform creative direction to refine or override the preset.

## Creative laws

These apply to every brag video regardless of tone.

**Short.** 15–25 seconds. Not one second more without a reason. This holds whether or not narration is on; narration does not extend the window.

**Readable.** Keep the pace high through motion and cuts, never by flashing text. Every line a viewer must read holds long enough to read it (short label ~0.8s settled; a sentence ~0.3s per word). Fast-in, then hold — never fast-in, then gone.

**Specific.** The video must feel like it was made for this exact project, not any project.

**Show the thing.** At least one scene must display actual UI, copy, or a key visual from the product. No abstract filler.

**No generic SaaS language.** "Streamline your workflow" is banned. Use the project's actual copy and claims.

**The hook is everything.** The first 2 seconds determine whether someone keeps watching. Plan the hook before anything else.

**Funny earns its place.** Humor should come from the project's absurdity, not from trying to be funny.

**Pattern:**
```
Hook (2-3s) → Reveal (2-4s) → 2-3 sharp highlights (5-12s) → Punchline/outro (2-4s)
```

Adapt this. Not every project needs exactly 3 highlights. The pattern is a starting shape, not a template.
