Important Notes#

• Task ID Validity: Task IDs are valid for 24 hours
• Video URL Validity: Generated video URLs are valid for 24 hours, download immediately
• Content Review: Both input and output are subject to content safety review
• Billing: Based on resolution (1080P > 720P) × duration (seconds)
• Multi-shot Narrative: Use natural language in prompt to describe shots (e.g., "第1个镜头[0-3秒]...")
• Migration from wan2.6: wan2.7 uses resolution + ratio instead of size, and shot_type parameter is deprecated (use prompt instead)
