Step 1 — Script Generation

Use LLM (Gemini / GPT)

Structure:

• Hook
• Problem
• Solution
• CTA

Step 2 — Voice Layer

• TTS / cloned voice
• keep sentences short
• natural tone

Step 3 — Video Layer

• avatar or stock visuals
• sync with audio

Step 4 — Editing Layer

• captions
• transitions
• pacing

What breaks

1. Long scripts
   → poor pacing

2. Generic output
   → low engagement

3. No structure
   → unusable video

Key insight

This is not video generation.

It’s content pipeline engineering.
