wan3.0-video

Capabilities

• Multimodal generation from text, first/last frames, references, or a public document or link; 2-30 seconds, 480P/720P/1080P and smart duration.
• Unified and native asynchronous API formats with the same API key.
• Locally measured output duration with failure refunds and request-time price freezing.

Limitations

• Completed media URLs expire after 24 hours; save the result promptly.
• Generation is probabilistic; a seed does not guarantee identical media.
• Use audio=true for sound or false for no audio track. Sound and silent prices are equal.

Use cases

• Cinematic advertising and branded storytelling.
• Visual storyboards and reference-directed creative production.
• Automated video creation with task polling and USD usage tracking.
