[Strengths] Provided enhanced dynamic camera movements and rich lighting effects. Maintained for backward compatibility. [Best For] Existing legacy integrations and workflows that strictly depend on this specific model version's quirks. [Limitations] Do NOT use this for new creations. It is a legacy model maintained for backward compatibility. [Routing] Only use if explicitly requested; otherwise use Wan 2.7 Video Editing. ## OpenAPI ````yaml /model-api/alibaba/alibaba-v2v.json post /alibaba/wan2.2-animate-mix openapi: 3.1.0 info: description: The video-to-video models API from Alibaba. version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: Alibaba Video-to-Video Models API servers: - url: https://api.modellix.ai/api/v1 description: The video-to-video models API from Alibaba. security: - bearerAuth: [] paths: /alibaba/wan2.2-animate-mix: post: summary: Wan 2.2 Animate Mix - Character Replacement in Video description: >- [Core Function] Wan 2.2 Animate Mix - Character Replacement in Video is a legacy video editing and motion transfer model.

Format: JPG/JPEG/PNG/BMP/WEBP. Size: width and height both in [200, 4096] pixels, aspect ratio 1:3 to 3:1. File size: ≤ 5MB. Content requirement: ensure the character in image has similar aspect ratio to the character in reference video for best results example: https://example.com/new_character.jpg video_url: type: string format: uri description: >- Reference video URL with the original character to be replaced (HTTP/HTTPS, publicly accessible, no Chinese or non-ASCII characters). Format: MP4/AVI/MOV. Duration: 2-30 seconds. Size: width and height both in [200, 2048] pixels, aspect ratio 1:3 to 3:1. File size: ≤ 200MB. The model will replace the character in this video while preserving scene, lighting, and color tone. Tip: Higher resolution and frame rate improve output quality example: https://example.com/original_scene.mp4 mode: type: string description: >- Model service mode. Options: (1) 'wan-std': Standard mode - faster generation, cost-effective, suitable for quick preview and basic character replacement; (2) 'wan-pro': Professional mode - higher animation smoothness and better quality, suitable for film post-production and final output enum: - wan-std - wan-pro example: wan-std check_image: type: boolean description: >- Whether to perform image quality detection. When true (default), validates input image quality and content. When false, skips detection for faster processing. Recommended to keep true for production use to ensure best results default: true example: true AsyncTaskResponse: type: object required: - code - message - data properties: code: type: integer description: Response code, 0 indicates success example: 0 message: type: string description: Response message example: success data: type: object required: - status - task_id - model_id properties: status: type: string enum: - pending - processing description: Task status example: pending task_id: type: string description: Unique task identifier example: task-abc123 model_id: type: string description: Model ID example: model-123 get_result: type: object description: API information to query the task result properties: method: type: string description: HTTP method example: GET url: type: string description: Full URL to query the task result example: https://api.modellix.ai/api/v1/tasks/task-abc123 description: Detailed data about the submitted asynchronous task. securitySchemes: bearerAuth: type: http scheme: bearer description: 'API Key authentication.
