# Veo3 動画生成

> Generate high-quality videos using Google Veo3 model, supports async task management

> [!NOTE]
>
> **中国本土のユーザー向け：** 中国本土のユーザーは `https://toapis.cn` を API エンドポイント（Base URL）としてご利用ください。本ドキュメント内の例では `https://toapis.com` を `https://toapis.cn` に置き換えてください。

* Asynchronous processing mode, returns task ID for subsequent queries
* Supports multiple generation modes including text-to-video and image-to-video
* Generated video links are valid for 24 hours, please save them promptly

> [!WARNING]
>
> **Important Change**: For better performance and cost control, we no longer support passing base64 image data directly in `image_urls`. Please use the [Upload 画像API](https://docs.toapis.com/docs/ja/api-reference/uploads/images.md) first to upload images and get URLs, then call this endpoint.

## Body

**model** `string` *required* (default: veo3.1-fast)

Video generation model name

Available models:

* `veo3.1-fast` - Fast generation model, suitable for quick preview and iteration
* `veo3.1-quality` - High-quality generation model, suitable for final production
* `veo3.1-lite` - Lightweight generation model, suitable for lower-cost fast generation

Example: `"veo3.1-fast"`

**prompt** `string` *required*

Text description for video generation

**duration** `integer`

Video duration (seconds)

Fixed value: `8` (VEO3 only supports 8-second duration)

**aspect\_ratio** `string`

Video resolution

Supported formats:

* `16:9` (landscape)
* `9:16` (portrait)

**image\_urls** `string[]`

Array of reference image URLs for image-to-video generation

**⚠️ URL format only (base64 no longer supported)**

* Publicly accessible image URL (http\:// or https\://)
* You can use the [Upload 画像API](https://docs.toapis.com/docs/ja/api-reference/uploads/images.md) to upload local images and get URLs

**Limits:**

* Maximum file size: 10MB
* Supported formats: .jpeg, .jpg, .png, .webp

**metadata** `object`

VEO3-specific extended parameters

**Show metadata fields**

**generation\_type** `string`

Video generation type

Supported types:

* `frame` - Frame-to-video (FL mode)
* `reference` - Reference image-to-video

If not provided, automatically determined by image count: 2 images for frame mode, 3 images for reference mode

**Note: `veo3.1-quality` model does not support `reference` mode**

**resolution** `string`

Video resolution

Supported values:

* `720p` (default)
* `1080p`
* `4k`

**enable\_gif** `boolean`

Enable GIF output format. Default: `false`

Note: GIF cannot be used with 1080p or 4k resolution

## レスポンス

**id** `string`

Unique task identifier for status queries

**object** `string`

Object type, always `generation.task`

**model** `string`

モデル name used

**status** `string`

Task status

* `queued` - Queued for processing
* `in_progress` - Processing
* `completed` - Successfully completed
* `failed` - Failed

**progress** `integer`

Task progress percentage (0-100)
