# Veo3 Official 動画生成

> Generate high-quality videos using Google Veo3 official direct-connect models, with advanced features like audio generation and keyframe control

* Asynchronous processing mode, returns a task ID for subsequent status queries
* Direct connection to Google Vertex AI, supporting all native Veo parameters
* Supports text-to-video, image-to-video, and keyframe interpolation generation modes
* 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 Image endpoint](../../uploads/images) to upload images first, then use the returned URL in this API.
</Warning>

## Authorizations

<ParamField header="Authorization" type="string" required>
  All endpoints require Bearer Token authentication

  Get API Key: Visit the [API Key Management page](https://toapis.com/console/token) to obtain your API Key

  Add to request headers:

  ```
  Authorization: Bearer YOUR_API_KEY
  ```
</ParamField>

## Body

<ParamField body="model" type="string" default="Veo3.1-quality-official" required>
  Video generation model name

  Available models:

  * `Veo3.1-quality-official` - High-quality generation model, ideal for final production
  * `Veo3.1-fast-official` - Fast generation model, ideal for quick previews and iteration

  Example: `"Veo3.1-quality-official"`
</ParamField>

<ParamField body="prompt" type="string" required>
  Text description for video generation
</ParamField>

<ParamField body="duration" type="integer">
  Video duration in seconds

  Supported values:

  * `4` - 4 seconds
  * `6` - 6 seconds
  * `8` - 8 seconds (default)
</ParamField>

<ParamField body="size" type="string">
  Video aspect ratio

  Supported formats:

  * `16:9` (landscape, default)
  * `9:16` (portrait)
</ParamField>

<ParamField body="resolution" type="string">
  Video resolution

  Supported values:

  * `720p` (default)
  * `1080p`
  * `4k` (preview)
</ParamField>

<ParamField body="image_urls" type="string[]">
  **First frame reference image** for image-to-video generation. The video will begin from this image. Only the first URL in the array is used.

  **⚠️ Only URL format is supported (base64 is no longer supported)**

  * Publicly accessible image URLs (http\:// or https\://)
  * Use the [Upload Image endpoint](../../uploads/images) to upload local images and get URLs

  **Limits:**

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

  <Warning>
    `image_urls` and `metadata.referenceImages` **cannot be used together**. If both are provided, `image_urls` (first frame) takes priority and `referenceImages` will be ignored.
  </Warning>
</ParamField>

<ParamField body="metadata" type="object">
  Veo3 Official specific extension parameters

  <Expandable title="Show metadata fields">
    <ParamField body="generateAudio" type="boolean">
      Whether to generate audio. Default: `false`

      When enabled, the video will include AI-generated sound effects and ambient audio
    </ParamField>

    <ParamField body="negativePrompt" type="string">
      Negative prompt describing content you don't want in the video

      Example: `"blurry, low quality, distorted"`
    </ParamField>

    <ParamField body="personGeneration" type="string">
      Person generation safety setting

      Supported values:

      * `allow_adult` - Allow generating adult people
      * `dont_allow` - Don't allow generating people
    </ParamField>

    <ParamField body="lastFrame" type="string">
      Last frame image URL for keyframe interpolation video generation

      **Must** be used together with `image_urls` (first frame) to generate a transition video from the first frame to the last frame. Has no effect without `image_urls`.
    </ParamField>

    <ParamField body="referenceImages" type="string[]">
      Style/asset reference image URL array. The video will incorporate the visual style and elements from these images (they are NOT used as the starting frame).

      **Limit: maximum 3 images**

      **⚠️ Cannot be used together with `image_urls`** — these are mutually exclusive in the Veo API. Use `image_urls` if you need first-frame control.
    </ParamField>

    <ParamField body="compressionQuality" type="string">
      Video compression quality

      Supported values:

      * `optimized` (default) - Optimized compression
      * `lossless` - Lossless compression
    </ParamField>

    <ParamField body="resizeMode" type="string">
      Image resize mode for image-to-video generation

      Supported values:

      * `pad` - Pad mode, preserves original aspect ratio
      * `crop` - Crop mode, fills the frame
