Prompt Guide

How to write video generation prompts for Wan3.0

Modular Structure

1. Reference layer: correspondence between subjects and assets
2. Global setup: scene, style, lighting, materials, and color
3. Camera language: shot size, angle, movement, and cuts
4. Timeline: what happens in each segment and how long it lasts
5. Performance & sound: motion, dialogue, ambience, and music
6. Exclusions: errors and style drift you don't want to see

Write Motion, Not Just Adjectives

Don't just write "the character fights" or "the character flies" — describe how the motion starts, how it accelerates, how it stops, and how it affects clothing, hair, dust, water, and sound. "Hold in place — instant launch — hard stop — sharp-angle turn" is far more controllable than "flies quickly."

Maintain Shot Continuity

For long takes, orbits, pans, and tracking shots, always specify camera direction, subject orientation, and spatial anchor points. For complex action scenes, you can designate fixed anchors such as the edge of a reed bed, a rock formation, or a lakeshore.

Describe the Sound Layers Separately

  1. Dialogue and character voice timbre;
  2. Action sound effects such as footsteps, punches, metal impacts, and splashes;
  3. Ambient sound such as wind, rain, insects, and equipment hum;
  4. The timing of music entry, climax, and stop.

Any sound you don't want should be explicitly excluded — e.g., "no music," "no subtitles," or "no dialogue."

Common Exclusions

No subtitles, no extra characters, no subject drifting off-mark, no camera resets, no clipping, no broken limbs, no incorrect slow motion, no physics-defying floating, and don't let background music overpower dialogue or ambient sound.
