> 字节跳动 Seedance 1.0 Pro 图生视频模型，使用参考图片作为首帧（和尾帧）生成视频。

Seedance 1.0 Pro 图生视频 是字节跳动 Seedance 系列的图生视频模型，通过 Starrise AI API 提供服务。使用参考图片作为首帧（和尾帧）生成视频。

## 核心能力

* **图生视频** — 使用参考图片作为首帧
* **首尾帧控制** — 同时指定起始帧和结束帧图片
* **灵活时长** — 2–12 秒
* **多种比例** — 16:9、4:3、1:1、3:4、9:16、21:9、adaptive
* **多种分辨率** — 480p、720p、1080p

      {"type": "image_url", "image_url": {"url": "https://example.com/photo.jpg"}, "role": "first_frame"}
    ],
    "ratio": "adaptive",
    "duration": 5,
    "resolution": "720p"
  }'
```

```python Python theme={null}
