Wan 2.2 Animate Move (Image-to-Motion)

Validation

mkdir -p output/aliyun-wan-animate-move
python -m py_compile skills/ai/video/aliyun-wan-animate-move/scripts/generate_animate_move.py && echo "py_compile_ok" > output/aliyun-wan-animate-move/validate.txt

Pass criteria: command exits 0 and output/aliyun-wan-animate-move/validate.txt is generated.

Output And Evidence

• Save task IDs, polling responses, and final video URLs to output/aliyun-wan-animate-move/.
• Keep at least one end-to-end run log for troubleshooting.

Prerequisites

• Install SDK (recommended in a venv):

python3 -m venv .venv
. .venv/bin/activate
python -m pip install requests

• Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.

Critical model names

• wan2.2-animate-move -- supports motion transfer from reference video to character image

Capabilities

Capability	Description	Required inputs
Motion transfer	Transfer actions/expressions from reference video to character image	image_url + video_url

Service modes

Mode	Description
wan-std	Standard mode, faster generation, cost-effective, suitable for preview and basic animation

Quick start (Python + HTTP)

import os
import json
import time
import requests

API_KEY = os.getenv("DASHSCOPE_API_KEY")
BASE_URL = "https://dashscope.aliyuncs.com/api/v1"

def create_animate_move_task(image_url: str, video_url: str, mode: str = "wan-std") -> str:
    """Create an animate-move task and return task_id."""
    payload = {
        "model": "wan2.2-animate-move",
        "input": {
            "image_url": image_url,
            "video_url": video_url,
            "watermark": False,
        },
        "parameters": {
            "mode": mode,
        },
    }
    resp = requests.post(
        f"{BASE_URL}/services/aigc/image2video/video-synthesis",
        headers={
            "Authorization": f"Bearer {API_KEY}",
            "Content-Type": "application/json",
            "X-DashScope-Async": "enable",
        },
        json=payload,
    )
    resp.raise_for_status()
    data = resp.json()
    return data["output"]["task_id"]


def poll_task(task_id: str, interval: int = 15) -> dict:
    """Poll until task completes. Returns final response."""
    while True:
        resp = requests.get(
            f"{BASE_URL}/tasks/{task_id}",
            headers={"Authorization": f"Bearer {API_KEY}"},
        )
        resp.raise_for_status()
        data = resp.json()
        status = data["output"]["task_status"]
        if status in ("SUCCEEDED", "FAILED", "CANCELED"):
            return data
        time.sleep(interval)

Error handling

Error	Likely cause	Action
401/403	Missing or invalid DASHSCOPE_API_KEY	Check env var or credentials file
400 InvalidParameter	Unsupported image/video format, bad dimensions, missing fields	Validate parameters
"does not support synchronous calls"	Missing X-DashScope-Async: enable header	Add required header
429	Rate limit or quota	Retry with backoff

Output location

• Default output: output/aliyun-wan-animate-move/videos/
• Override base dir with OUTPUT_DIR.

Anti-patterns

• Do not use model names other than wan2.2-animate-move.
• Do not call this API synchronously -- async header is required.
• Do not use multiple people in image or video -- single person only.
• Video URLs expire after 24 hours; download and persist immediately.
• Do not use images with occluded faces or extreme proportions.

Workflow

1. Confirm user intent: transfer motion from reference video to character image.
2. Select service mode: wan-std (fast/cheap) or wan-pro (high quality).
3. Prepare image URL and video URL with valid formats and dimensions.
4. Create async task and poll for results.
5. Download and save generated video before URL expiration.
