# Kling 2.5 Turbo Pro

> Kling 2.5 Turbo Pro API 可根据提示词生成 5 或 10 秒的视频，可选提供首帧、尾帧或两者。

> [!TIP]
>
> 1. 提交后会返回 `task_id`。如果提供了 `callback_url`，当任务状态变为 `finished` 或 `failed` 时，系统会向 `callback_url` 发送 POST 请求。
> 2. 无论是否提供 `callback_url`，都可以通过统一的[查询任务状态](https://docs.poyo.ai/zh/api-manual/task-management/status.md)接口获取结果。

`kling-2.5-turbo-pro` 在同一请求格式下支持仅用提示词生成，以及可选的首/尾帧引导。

## 模型

* **kling-2.5-turbo-pro** - 文生视频，可选帧引导

## 必填参数

* **prompt**：用于生成的文本提示词

## 可选参数

* **duration**：`5` 或 `10`。默认为 `5`
* **start\_image\_url**：可选的首帧图片
* **end\_image\_url**：可选的尾帧图片
* **aspect\_ratio**：可选的字符串值
* **negative\_prompt**：可选的负面提示词

## 注意事项

* 可以只提交提示词
* 也可以提供 `start_image_url`、`end_image_url` 或两者

                      A man in a trench coat holding a black umbrella walks
                      briskly through the streets of Tokyo on a rainy night,
                      splashing through puddles. A handheld follow-cam shot from
                      his side and slightly behind. The focus is locked on the
                      man, while background neon signs blur into beautiful
                      bokeh. Cyberpunk aesthetic with a film noir quality; the
                      mood is mysterious and lonely. The pavement is slick and
                      wet, reflecting the vibrant neon signs. Individual
                      raindrops are visible, and a light fog hangs in the air.
