Kling 3.0 Turbo 视频生成

• 异步处理模式，返回任务ID用于后续查询
• 支持文本转视频、图生视频（首帧控制）
• 支持 720P / 1080P 两档清晰度
• 支持 3-15 秒视频时长
• 支持多镜头分镜（通过固定格式提示词表达）

认证

Authorization · string · 必填

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 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 · 必填

视频生成模型名称

支持的模型：

• kling-3.0-turbo - 可灵 3.0 Turbo

prompt · string · 必填

文本提示词

上游限制不超过 3072 字符，建议不超过 2500 字符。

示例："一只柯基在海边奔跑，电影感，黄昏光线"

first_frame_image · string

支持 图片 URL 或 Base64。

首帧图上游限制：

• 格式：.jpg / .jpeg / .png
• 大小：≤ 50MB
• 宽高：≥ 300px
• 宽高比：1:2.5 ~ 2.5:1

aspect_ratio · string · 默认值: "16:9"

视频宽高比

可选值：

• 16:9 - 横屏
• 9:16 - 竖屏
• 1:1 - 方形

默认值：16:9

仅文生视频生效。图生视频时此字段无效，视频比例由首帧图决定。

resolution · string · 默认值: "720p"

视频清晰度

可选值：

• 720p
• 1080p

默认值：720p

duration · integer · 默认值: "5"

视频时长（秒）

取值范围：3-15（最短 3 秒，最长 15 秒）

默认值：5

⚠️ 注意： 必须输入纯数字（如 6），不要加引号，否则会报错

watermark · boolean

是否添加水印

仅当显式传入时才下发到上游；不传则不添加水印。

​

文生视频 vs 图生视频

系统会根据是否提供 first_frame_image 自动判断生成模式：有首帧图走图生视频，无首帧图走文生视频，用户无需显式声明。

参数	文生视频	图生视频
prompt	✅ 必填	✅ 可选（留空纯按首帧图生成）
first_frame_image	❌ 不传	✅ 必填
aspect_ratio	✅ 可选	❌ 无效（比例由首帧图决定）
resolution	✅ 可选	✅ 可选
duration	✅ 可选（3-15）	✅ 可选（3-15）
watermark	✅ 可选	✅ 可选

​

响应

code · integer

响应状态码，成功时为 200

data · array

返回数据数组

显示 数组元素

status · string

任务状态，初始提交时为 submitted

task_id · string

任务唯一标识符，用于查询任务状态和结果

​
