认证

Authorization string

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://openveer.com) 获取您的 API Key 使用时在请求头中添加： ``` Authorization: Bearer YOUR_API_KEY ```

请求参数

model string

视频生成模型名称支持的模型： * `veo3.1-fast-official` - Veo 3.1 官方快速版 * `veo3.1-quality-official` - Veo 3.1 官方高质量版

prompt string

正向文本提示词建议详细描述场景、动作、风格等，以获得更好的生成效果。建议使用英文提示词。示例：`"a golden retriever running on the beach, sunset, cinematic"`

negative_prompt string

负面提示词，用于排除不想要的内容示例：`"blurry, low quality, watermark, text"`

duration integer

视频时长（秒）建议使用：`4` / `6` / `8` 默认值：`8` **⚠️ 注意：** 必须输入纯数字（如 `8`），不要加引号，否则会报错

aspect_ratio string

视频宽高比可选值： * `16:9` - 横屏 * `9:16` - 竖屏默认值：`16:9`

resolution string

视频分辨率可选值： * `720p` - 标准分辨率 * `1080p` - 高清分辨率 * `4K` - 超高清分辨率默认值：`720p`

first_frame_image string

首帧图片 URL，用于图生视频

警告

* 图片 URL 必须公开可访问，不能有防盗链 * 建议使用对象存储 URL，而非临时下载地址

last_frame_image string

尾帧图片 URL，用于图生视频与 `first_frame_image` 配合使用，实现首尾帧控制

seed integer

随机种子，用于复现生成结果取值范围：`0` - `4294967295`

sample_count integer

生成样本数量 1-4，当前建议填 `1` 默认值：`1`

generate_audio boolean

是否生成音频轨道

person_generation string

人物生成策略可选值： * `allow_adult` - 只允许生成成人人物/成人面孔 * `disallow` - 不允许生成人物或人脸默认值：`allow_adult`

resize_mode string

图片缩放策略（图生视频时生效）可选值： * `pad` - 填充模式 * `crop` - 裁剪模式默认值：`pad`

enhance_prompt boolean

是否启用上游提示词增强默认值：`true`

警告

* 该参数只能设置为 `true`，设置为 `false` 会导致请求报错 * 如不需要此参数，请勿传入

文生视频 vs 图生视频

系统通过是否传入图片参数自动判断模式：不传图片为文生视频，传图片为图生视频。

参数	文生视频	图生视频
`prompt`	✅ 必填	✅ 必填
`first_frame_image`	❌ 不传	✅ 至少传一个
`last_frame_image`	❌ 不传	✅ 可选（尾帧）
`negative_prompt`	✅ 可选	✅ 可选
`duration`	✅ 可选	✅ 可选
`aspect_ratio`	✅ 可选	✅ 可选
`resolution`	✅ 可选	✅ 可选
`seed`	✅ 可选	✅ 可选
`generate_audio`	✅ 可选	✅ 可选
`person_generation`	✅ 可选	✅ 可选
`resize_mode`	❌ 不适用	✅ 可选
`enhance_prompt`	✅ 可选	✅ 可选

响应

code integer

响应状态码，成功时为 200

data array

task_id string

任务唯一标识符，用于查询任务状态和结果

使用场景

场景 1：文生视频（基础）

{
  "model": "veo3.1-fast-official",
  "prompt": "a golden retriever running on the beach, sunset, cinematic"
}

场景 2：文生视频（完整参数）

{
  "model": "veo3.1-quality-official",
  "prompt": "a cinematic close-up of a ragdoll cat slowly walking through a sunlit living room",
  "negative_prompt": "blurry, low quality, watermark, text",
  "duration": 8,
  "aspect_ratio": "16:9",
  "resolution": "1080p",
  "seed": 12345,
  "generate_audio": true,
  "person_generation": "disallow",
  "enhance_prompt": true
}

场景 3：图生视频（单张首帧）

{
  "model": "veo3.1-fast-official",
  "prompt": "the cat slowly walks forward and looks around",
  "first_frame_image": "https://example.com/cat.png",
  "duration": 8,
  "resolution": "720p"
}

场景 4：图生视频（首帧 + 尾帧）

{
  "model": "veo3.1-quality-official",
  "prompt": "smooth cinematic transition from the first frame to the last frame",
  "first_frame_image": "https://example.com/frame-start.png",
  "last_frame_image": "https://example.com/frame-end.png",
  "duration": 8,
  "resolution": "1080p"
}

场景 5：生成带音频的视频

{
  "model": "veo3.1-quality-official",
  "prompt": "a busy coffee shop with people chatting and barista making latte art",
  "duration": 8,
  "generate_audio": true,
  "aspect_ratio": "16:9"
}

注意

**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。
