# VEO3 视频编辑

>  - 基于已生成的视频进行续写编辑，将 8 秒视频续写到 15 秒
- 异步处理模式，返回任务ID用于后续查询
- 生成的视频链接有效期为24小时，请尽快保存 

> [!NOTE]
>
> **模型名兼容提示**：本接口同时兼容别名 `veo3.1-fast-ext`（等价于 `veo3.1-fast`）、`veo3.1-quality-ext`（等价于 `veo3.1-quality`），别名与主名可互换使用、效果一致。

## 路径参数

**task\_id** `string` *required*

原视频任务 ID

这是之前通过视频生成接口返回的 task\_id，原始视频任务状态必须为 `success`

## 认证

**Authorization** `string` *required*

所有 API 端点都需要 Bearer Token 认证

获取您的 API Key：

访问 [API Key 管理页面](https://apimart.ai/keys) 以获取您的 API Key

将其添加到请求头中：

```
Authorization: Bearer YOUR_API_KEY
```

## 请求参数

**model** `string` *required*

视频模型名称，必须与原视频使用的模型一致

支持的模型：

* `veo3.1-fast` - 快速版本（兼容别名 `veo3.1-fast-ext`）
* `veo3.1-quality` - 高质量版本（兼容别名 `veo3.1-quality-ext`）

示例：`"veo3.1-fast"`

> [!NOTE]
>
> 为兼容旧版调用，别名 `veo3.1-fast-ext`（对应 `veo3.1-fast`）、`veo3.1-quality-ext`（对应 `veo3.1-quality`）仍可正常使用。

**nsfw\_check** `boolean` (default: 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）

**prompt** `string` *required*

续写提示词，描述延长部分的内容

**raw** `boolean`

是否只返回延长部分的视频

* `true` - 只返回延长后的视频

默认值：`false`

**aspect\_ratio** `string`

延长视频的比例

支持的值：

* `16:9`
* `9:16`

**resolution** `string`

视频分辨率

支持的值：

* `720p`（默认）
* `1080p`
* `4k`

## 注意事项

> [!NOTE]
>
> **model 必须一致**：延长时的 model 必须与生成原始视频时使用的模型相同。用 `veo3.1-fast` 生成的视频，延长时也必须填 `veo3.1-fast`。

> [!NOTE]
>
> **仅支持已完成的视频**：原始视频任务状态必须为 `success`。

> [!NOTE]
>
> **URL 中的 task\_id**：是第一步生成视频时返回的 `task_id`（非上游 ID）。

## Response

**code** `integer`

响应状态码

**data** `object[]`

响应数据数组

**属性**

**task\_id** `string`

新的任务 ID，用于查询延长视频的状态

**status** `string`

任务状态

可能的值：

* `submitted` - 已提交
