Kling-V3 动作控制
- Kling-V3 Motion Control (kling-v3-motion-control) 模型支持通过参考图片 + 参考视频驱动动作生成
- 系统从参考视频中提取运动轨迹,将其应用到参考图片中的角色/物体上,生成与参考视频动作一致的新视频
- 生成视频时长取决于
character_orientation:image最长 10 秒,video最长 30 秒,最短 3 秒 - 异步处理模式,使用返回的任务ID 进行查询
- 生成的视频链接,有效期为24小时,请尽快保存

请求体
application/json
视频生成模型名称
可用选项:
kling-v3-motion-control 示例:
"kling-v3-motion-control"
参考图片URL数组,用于提供角色/物体的外观来源
注意:
- 传入一张参考图片
- 图像大小:不超过
10MB - 支持的文件格式:
.jpg、.jpeg、.png - 图像尺寸:宽高 ≥
300px,宽高比在1:2.5~2.5:1之间 - 图像URL需要服务器能直接访问
示例:
["https://example.com/character.jpg"]
参考视频URL数组,用于提供动作轨迹来源
注意:
- 传入一个参考视频
- 视频时长:
3~30秒 - 视频大小:不超过
100MB - 视频尺寸:宽高单边
340px~3850px - 避免切镜、快运动和场景切换
- 视频URL需要服务器能直接访问
示例:
["https://example.com/dance-reference.mp4"]

文本提示词(可选),用于引导生成内容
注意:
- 最长
2500字符 - 可留空,模型会自动根据参考图片和视频生成
Maximum string length:
2500示例:
"A girl dancing gracefully"
分辨率档位
说明:
720p:标准画质(std)1080p:高品质画质(pro)
可用选项:
720p, 1080p 示例:
"720p"
任务完成后的HTTPS回调地址
回调时机:
- 任务完成(completed)、失败(failed)或取消(cancelled)时触发
- 在计费确认完成后发送
安全限制:
- 仅支持HTTPS协议
- 禁止回调到内网IP地址(127.0.0.1、10.x.x.x、172.16-31.x.x、192.168.x.x等)
- URL长度不超过
2048字符
回调机制:
- 超时时间:
10秒 - 失败后最多重试
3次(会分别在失败的1秒/2秒/4秒后进行重试) - 回调响应体格式与任务查询接口返回的格式一致
- 回调地址若返回2xx状态码视为成功,其他状态码会触发重试
示例:
"https://your-domain.com/webhooks/video-task-completed"
