V. Advanced Tips for Hard-Hitting Trailer Narration
- Use short lines: 5–10 words per sentence for impact. Example: “Darkness is coming.”
- Think in three acts: setup → conflict → climax, and escalate vocal emotion accordingly.
- Stress keywords: naturally emphasize phrases like “legendary sword” and “fate in your hands”.
- Use silence intentionally: leave ~0.5–1s between key lines to let moments land.
- Sync with visuals: align key words with visual peaks and cuts.
