Wan 3.0 Video Duration Guide

Longer clips are not automatically better. For production work, duration should be chosen around one clear action per shot, continuity risk and the cost of failed generations.

How GenVideoKit structures Wan 3.0 prompts

Describe composition, subject motion, environment motion, camera behavior and temporal continuity explicitly. Keep cause-and-effect clear, maintain stable identity/geometry, and specify reference relationships when used. Audio direction may be included for current multimodal Wan workflows.

Production shortcut

Use one main action per clip. If the idea needs several distinct beats, split it in Scene Builder instead of forcing everything into one long generation.

How to choose clip length

  1. Use a short validation render for a risky motion or identity-heavy shot.
  2. Give the action enough time to complete naturally; avoid cramming several story beats into one generation.
  3. Split long ideas into connected scenes and use the previous last frame as the next visual anchor.
  4. Price retries, not only the final accepted duration.
