当单张源图片不足以满足需求，而你希望 Kling 基于多张图片参考构建运动时，请使用此端点。

​
调用前准备

  • 在 image_list 中准备 2 到 4 张图片
  • 从 model_name: kling-v1-6 或你已验证的其他当前模型开始
  • 首次测试尽量保持简单：使用一条简短的 prompt，不使用运动遮罩，也不添加额外的回调设置

​
任务流程

1

提交多图请求

发送图片列表、prompt 和时长，然后保存返回的 Kling task_id。
2

轮询任务

继续参考 单项查询，直到任务进入终态。
3

持久化结果

如果你需要在供应商交付 URL 之外继续保留结果，请存储已完成的视频。
完整参数说明请参见 Kling 官方文档。
