Features

Wan 3.0 Prime Text-to-Video generates coherent cinematic videos from natural-language prompts. It supports flexible duration, multiple aspect ratios, optional audio generation, and prompt expansion for more deliberate prompt interpretation.

Parameters

How to Use

1. Write your prompt — Describe the scene, subject, motion, camera movement, lighting, and visual style.
2. Choose resolution — Use 480p for lower-cost drafts, 720p for balanced output, or 1080p for higher quality.
3. Set aspect ratio — Select the format that matches your target platform or creative direction.
4. Set duration — Choose a duration from 2 to 30 seconds.
5. Configure audio optional — Keep enable_audio enabled when audio is needed.
6. Enable prompt expansion optional — Use enable_prompt_expansion when the prompt needs more deliberate interpretation.
7. Submit — Generate the final text-to-video output.

Pricing

Pricing is based on output resolution and billed duration.

Billed duration is rounded up to the next whole second and clamped to the 2–30s range.

Example Costs

Best Use Cases

• Cinematic storytelling — Generate short cinematic scenes from detailed text prompts.
• Concept visualization — Turn written ideas into motion previews for creative planning.

• Prompt iteration — Test different camera movements, lighting styles, and motion directions.

Pro Tips

• Include subject, action, environment, camera movement, lighting, mood, and visual style in the prompt.
• Use 480p for quick drafts and 1080p for higher-quality output.

• Enable enable_prompt_expansion for complex prompts with multiple visual or motion requirements.
• Set a fixed seed when you want more reproducible results.
