​
Generation Modes

Different modes are automatically selected based on the number of images in imageUrls:

​
1 Image — First Frame Mode

The image is used as the first frame of the video, and subsequent animation is generated based on the prompt. 
{
  "model": "seedance-2.0-pro",
  "input": {
    "prompt": "吹灭蜡烛",
    "imageUrls": ["https://assets.movart.ai/landingpage/dog.webp"]
  }
}

​
2 Images — First & Last Frame Mode

The first image serves as the video’s first frame, the second image as the last frame, and the AI automatically generates the transition animation in between. 
{
  "model": "seedance-2.0-pro",
  "input": {
    "prompt": "变身",
    "imageUrls": [
      "https://assets.movart.ai/3D-Cartoon.jpg",
      "https://assets.movart.ai/landingpage/dog.webp"
    ]
  }
}

​
3+ Images — Multi-Image Reference Mode

Use @1, @2, @3 in the prompt to reference the corresponding images by position. 
{
  "model": "seedance-2.0",
  "input": {
    "prompt": "@1 和 @2 在聊天，@3 在旁边看",
    "imageUrls": [
      "https://assets.movart.ai/3D-Cartoon.jpg",
      "https://assets.movart.ai/landingpage/dog.webp",
      "https://assets.movart.ai/landingpage/dog.webp"
    ]
  }
}
