## 认证

<ParamField header="Authorization" type="string" required>
  所有接口均需要使用 Bearer Token 进行认证

  获取 API Key：

  访问 [API Key 管理页面](https://xcompute.us/keys) 获取您的 API Key

  使用时在请求头中添加：

  ```
  Authorization: Bearer YOUR_API_KEY
  ```
</ParamField>

## 请求参数

</ParamField>

<ParamField body="prompt" type="string" required>
  视频内容描述

  建议详细描述场景、动作、风格等，以获得更好的生成效果

  示例：`"海边日落，金色阳光洒在海面上，海浪轻轻拍打沙滩"`
</ParamField>

<ParamField body="seed" type="integer">
  种子整数，用于控制生成内容的随机性

  取值范围：`-1` \~ `2^32-1` 之间的整数

  <Note>
    * 相同的请求下，模型收到不同的 seed 值（如：不指定 seed 值或令 seed 取值为 -1，会使用随机数替代），将生成不同的结果
    * 相同的请求下，模型收到相同的 seed 值，会生成类似的结果，但不保证完全一致
  </Note>
</ParamField>

<ParamField body="audio" type="boolean" default="false">
  是否生成音频

  设置为 `true` 时，视频将包含 AI 生成的配套音频

  默认值：`false`

## 使用场景

### 场景 1：带音频的文生视频

```json theme={null} theme={null}
{
  "model": "doubao-seedance-1-5-pro",
  "prompt": "海边日落，金色阳光洒在海面上，海浪轻轻拍打沙滩",
  "audio": true
}
```

### 场景 2：高质量竖屏短视频

```json theme={null} theme={null}
{
  "model": "doubao-seedance-1-5-pro",
  "prompt": "一位女孩在樱花树下旋转，花瓣随风飘落",
  "duration": 5,
  "aspect_ratio": "9:16",
  "resolution": "720p",
  "audio": true
}
```

### 场景 3：基于首帧生成动态视频

```json theme={null} theme={null}
{
  "model": "doubao-seedance-1-5-pro",
  "prompt": "让画面动起来，添加自然的动态效果",
  "image_urls": ["https://example.com/first.png"],
  "duration": 5,
  "audio": true
}
```

### 场景 4：首尾帧控制的转场效果

```json theme={null} theme={null}
{
  "model": "doubao-seedance-1-5-pro",
  "prompt": "画面从白天逐渐过渡到夜晚，城市灯光逐渐亮起",
  "image_with_roles": [
    {"url": "https://example.com/day.png", "role": "first_frame"},
    {"url": "https://example.com/night.png", "role": "last_frame"}
  ],
  "duration": 5
}
```

<Note>
  **查询任务结果**

  视频生成为异步任务，提交后会返回 `task_id`。使用 [获取任务状态](/cn/api-reference/tasks/status) 接口查询生成进度和结果。
</Note>
