當單一來源圖片不足以滿足需求，而你希望 Kling 根據多張圖片參考建立動作時，請使用此端點。

​
呼叫前準備

  • 在 image_list 中準備 2 到 4 張圖片
  • 先從 model_name: kling-v1-6 或你已驗證的其他現行模型開始
  • 首次測試請保持簡單：一段簡短 prompt、不使用動作遮罩、不加入額外的 callback 設定

​
任務流程

1

提交多圖請求

傳送圖片清單、prompt 與 duration，然後保存回傳的 Kling task_id。
2

輪詢任務

持續使用個別查詢，直到任務進入終態。
3

保存結果

如果你需要在供應商提供的交付 URL 保留期限之外持續保存，請儲存已完成的影片。
如需完整的參數參考，請參閱官方 Kling 文件。
