Kling 2.6 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/首尾帧控制)
  • 支持标准模式(720P)和专业模式(1080P)
  • 专业模式支持自动音频生成和指定音色

认证

Authorizationstring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

modelstring必填

视频生成模型名称

支持的模型:

  • kling-v2-6 - 可灵 v2.6(推荐)
nsfw_checkboolean默认 false

是否在提交视频任务前执行内容审核。

  • true:使用 omni-moderation-latest 审核提示词和输入图片
  • false 或不传:不发起审核请求,不增加审核成本与延迟(默认)
promptstring必填

正向文本提示词,不能超过 2500 个字符

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:"一只金色的猫咪在阳光下的草地上奔跑,慢动作,电影质感"

modestring默认 std

生成模式

可选值:

  • std - 标准模式(720P,仅支持无声视频)
  • pro - 专业模式(1080P,支持自动音频生成)

默认值:std

标准模式限制:std 模式仅支持无声视频,audio 参数需在 pro 模式下使用。

durationinteger默认 5

视频时长(秒)

可选值:5 或 10

默认值:5

aspect_ratiostring默认 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

negative_promptstring

负面提示词,用于排除不想要的内容

示例:"模糊, 低画质, 变形"

image_urlsarray<url>

图片 URL 数组,用于图生视频

  • 传 1 张:作为首帧图片
  • 传 2 张:自动分配为首帧 + 尾帧(需 mode: "pro")

最多支持 2 张图片

示例:["https://example.com/first.jpg"]

  • 最多支持 2 张图片
  • 首尾帧功能(传 2 张图片)仅支持 pro 模式,std 模式仅支持首帧(1 张图片)
  • 尾帧与音频互斥:在 pro 模式下,尾帧(传 2 张图片)和音频(audio: true)不能同时使用
  • 图生视频时,aspect_ratio 可能被图片实际比例覆盖
audioboolean默认 false

是否自动生成音频

默认值:false

  • 仅在 mode: "pro" 下可用
  • 与尾帧互斥:开启音频时不能同时使用尾帧(传 2 张图片)
watermarkboolean

是否添加水印

功能支持矩阵

类型 功能 std 5s std 10s pro 5s pro 10s
文生视频 视频生成 ✅(仅无声) ✅(仅无声) ✅ ✅
文生视频 自动音频 - - ✅ ✅
图生视频 视频生成 ✅(仅无声) ✅(仅无声) ✅ ✅
图生视频 首帧 ✅ ✅ ✅ ✅
图生视频 尾帧 - - ✅ ✅
图生视频 自动音频 - - ✅ ✅

注意:在 pro 模式下,尾帧和声音控制不能同时使用,二者互斥。

文生视频 vs 图生视频

系统通过是否传入 image_urls 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
image_urls ❌ 不传 ✅ 必填(1-2 张,尾帧需 pro)
negative_prompt ✅ 可选 ✅ 可选
mode ✅ 可选 ✅ 可选
duration ✅ 可选 ✅ 可选
aspect_ratio ✅ 可选 ⚠️ 可能被图片比例覆盖
audio ✅ 可选(需 pro) ✅ 可选(需 pro)
watermark ✅ 可选 ✅ 可选
