# UGC ads (CapCut-only)

> When you're testing whether ads work at all, the full pipeline is overkill. Claude writes 30 hooks; CapCut's AI voice library, stock footage, and auto-captions do everything else. Validate the angle, then graduate to ElevenLabs + Pika for the winners.

## Workflow

### 1. 30 hooks, 3 angles (Claude)

Same prompt as the recommended stack. The bottleneck is the hooks, not the tools.

**Prompt: 30 ad hooks across 3 angles**

```
Product brief:
"""
{{paste product brief: what it is, who it's for, what makes it different, 1 customer quote}}
"""

Generate 30 short-form ad hooks for vertical video ads, split evenly across 3 angles:

1. **Pain hook** — open with the audience's problem in their words.
2. **Solution hook** — open with the surprising mechanic or result.
3. **Social proof hook** — open with a specific outcome from a named (or anonymized) user.

For each hook:
- Format: "{HOOK LINE} (angle: pain/solution/proof)"
- 8 to 14 words, spoken-word friendly, hard consonants up front
- No "Are you tired of", no "Imagine if", no "Stop scrolling"
- One concrete noun or number per hook

Output as a numbered list 1 to 30.
```

### 2. Voice in CapCut (CapCut)

Open CapCut, paste the hook, pick a voice from the AI voice library. Render at default settings.

### 3. B-roll from CapCut stock (CapCut)

Search the built-in stock library by keyword from the hook. 4 to 6 clips per ad. Stock variety is shallow per niche; rotate aggressively.

### 4. Cut + caption + export (CapCut)

9:16, auto-captions, beat-align cuts, music duck. Export 1080p. Whole loop is 6 to 8 minutes per ad once you have the hooks.

## What it produced

**DTC founder, week 1 testing**

30 ads shipped at $0 spend on tooling. 3 angles tested across hooks. The 2 winners moved to the full pipeline (ElevenLabs + Pika) for production-quality scaling. The other 28 cost nothing to throw away.

## Pitfalls

- **CapCut voices have the AI tell** — Built-in voices are good enough for testing, not for production. Once an angle wins, re-render with ElevenLabs before scaling spend.
- **Stock library repetition** — After 10 to 15 ads in one niche, the same clips repeat. That's the signal to graduate to Pika or Runway for the winners.
- **Treating the test as the final cut** — Some founders ship the budget version to broad audiences and wonder why CTR is half what testing predicted. Test in cold audiences, scale only with the upgraded version.
