图片与多模态参考¶

首帧生成¶

首帧用于稳定人物、产品或场景外观。提示词仍应描述后续动作与镜头，而不是只重复图片内容。

{
  "model": "doubao-seedance-2-0-260128",
  "prompt": "保持人物外观一致，她向镜头微笑并轻轻挥手，镜头缓慢推进",
  "metadata": {
    "content": [
      {
        "type": "image_url",
        "image_url": {"url": "https://example.com/first.jpg"},
        "role": "first_frame"
      }
    ],
    "duration": 5,
    "ratio": "adaptive",
    "resolution": "720p",
    "watermark": false
  }
}

首尾帧¶

{
  "model": "doubao-seedance-2-0-260128",
  "prompt": "人物从画面左侧走到窗边，动作自然连贯，镜头平稳跟随",
  "metadata": {
    "content": [
      {
        "type": "image_url",
        "image_url": {"url": "https://example.com/first.jpg"},
        "role": "first_frame"
      },
      {
        "type": "image_url",
        "image_url": {"url": "https://example.com/last.jpg"},
        "role": "last_frame"
      }
    ],
    "duration": 5,
    "ratio": "adaptive",
    "resolution": "720p",
    "generate_audio": false,
    "watermark": false
  }
}

多张参考图¶

在提示词中用“图片 1、图片 2”明确每张图的作用，并保持 content 顺序一致。

{
  "model": "doubao-seedance-2-0-260128",
  "prompt": "人物参考图片1，手中的产品参考图片2；人物走入厨房并把产品递给家人",
  "metadata": {
    "content": [
      {
        "type": "image_url",
        "image_url": {"url": "https://example.com/person.jpg"},
        "role": "reference_image"
      },
      {
        "type": "image_url",
        "image_url": {"url": "https://example.com/product.jpg"},
        "role": "reference_image"
      }
    ],
    "duration": 8,
    "ratio": "9:16",
    "resolution": "720p",
    "generate_audio": true,
    "watermark": false
  }
}

多模态参考¶

可组合图片、参考视频与参考音频。素材越多并不一定越好：当角色、构图或节奏互相冲突时，模型更难遵循。

{
  "model": "doubao-seedance-2-0-260128",
  "prompt": "人物造型参考图片1，使用参考视频的平稳环绕运镜，背景采用参考音频",
  "metadata": {
    "content": [
      {
        "type": "image_url",
        "image_url": {"url": "https://example.com/character.jpg"},
        "role": "reference_image"
      },
      {
        "type": "video_url",
        "video_url": {"url": "https://example.com/camera.mp4"},
        "role": "reference_video"
      },
      {
        "type": "audio_url",
        "audio_url": {"url": "https://example.com/music.mp3"},
        "role": "reference_audio"
      }
    ],
    "duration": 10,
    "ratio": "16:9",
    "resolution": "720p",
    "generate_audio": true,
    "watermark": false
  }
}
