wan2.7-videoedit

Capabilities

• Prompt-guided editing with one source video and up to four reference images, source-length or truncated output, 720P/1080P, and original-audio preservation.
• 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_setting=auto or origin through the API. This preserves or regenerates audio, not a mute switch.

Use cases

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