[Strengths] It supports up to 5 reference videos with optional reference images and audio for multimodal composition and prompt-referenced subjects. [Best For] Highly recommended for: video-to-video transformation, multi-subject scenes that cite video1/image1 in the prompt, and extending creative edits from existing clips. [Limitations] Do NOT use this model for text-only, file/link, or first-frame-only workflows. video_urls is required. [Routing] Prefer this model when the user supplies reference video. Use Wan 3.0 T2V for prompt/file/link and Wan 3.0 I2V for image-first generation.","operationId":"wan30V2vAsync","requestBody":{"content":{"application/json":{"examples":{"reference_video":{"summary":"Reference video with images","value":{"duration":5,"prompt":"Video 1 holds image 1 and plays a calm folk song on the chair from image 2","ratio":"1:1","reference_images":["https://example.com/object.png","https://example.com/chair.png"],"video_urls":["https://example.com/role.mp4"]}},"video_only":{"summary":"Reference video only","value":{"duration":6,"prompt":"Restyle the clip into a rainy night cinematic look","resolution":"720P","video_urls":["https://example.com/input.mp4"]}}},"schema":{"description":"video_urls is required.
