Starting April 29, 2025, Gemini 1.5 Pro and Gemini 1.5 Flash models are not available in projects that have no prior usage of these models, including new projects. For details, see Model versions and lifecycle.

Generate videos using text prompts

You can use Veo on Vertex AI to generate new videos from a text prompt. Supported interfaces include the Google Cloud console and the Vertex AI API.

For more information about writing effective text prompts for video generation, see the Veo prompt guide.

Before you begin

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

Go to project selector

Enable the Vertex AI API.

Enable the API

In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

Go to project selector

Enable the Vertex AI API.

Enable the API

Set up authentication for your environment.

Select the tab for how you plan to use the samples on this page:
Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
REST

To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.
For more information, see Authenticate for using REST in the Google Cloud authentication documentation.

Generate videos from text

The following examples show how you can use text prompts to generate videos:

Console

In the Google Cloud console, go to the Vertex AI > Media Studio page.

Media Studio
Click Veo. The Veo Media Studio page is displayed.
Optional: In the Settings pane, configure the following settings:
- Model: choose a model from the available options.
  
  For more information about available models, see Veo models.
- Number of results: adjust the slider or enter a value. The maximum value depends on the model that you selected.
- Video length: select a length between 5 seconds and 8 seconds.
- Output directory: click Browse to create or select a Cloud Storage bucket to store output files.
Optional: In the Safety section, select one of the following Person generation settings:
- Allow (Adults only): default value. Generate adult people or faces only. Don't generate youth or children people or faces.
- Don't allow: don't generate people or faces.
Optional: In the Advanced options section, enter a Seed value. Providing a seed value ensures that you get the same output with the same text prompt.
In the Write your prompt box, enter your text prompt that describes the videos to generate.
Click Generate.

REST

After you set up your environment, you can use REST to test a text prompt. The following sample sends a request to the publisher model endpoint.

For more information about the Veo API, see the Veo on Vertex AI API.

Use the following command to send a video generation request. This request begins a long-running operation and stores output to a Cloud Storage bucket you specify.

Before using any of the request data, make the following replacements:
- PROJECT_ID: A string representing your Google Cloud project ID.
- MODEL_ID: A string respresenting the model ID to use. The following are accepted values:
  - "veo-2.0-generate-001"
  - "veo-3.0-generate-001"
  - "veo-3.0-fast-generate-001"
  - "veo-3.0-generate-preview" (Preview)
  - "veo-3.0-fast-generate-preview" (Preview)
- TEXT_PROMPT: The text prompt used to guide video generation.
- OUTPUT_STORAGE_URI: Optional: A string representing the Cloud Storage bucket to store the output videos. If not provided, video bytes are returned in the response. For example: "gs://video-bucket/output/".
- RESPONSE_COUNT: The number of video files to generate. The accepted range of values is 1-4.
- DURATION: An integer representing the length of the generated video files. The following are the accepted values for each model:
  - Veo 2 models: 5-8
  - Veo 3 models: 8
- Additional optional parameters
  
  Use the following optional variables depending on your use case. Add some or all of the following parameters in the "parameters": {} object.
```
"parameters": {
  "aspectRatio": "ASPECT_RATIO",
  "negativePrompt": "NEGATIVE_PROMPT",
  "personGeneration": "PERSON_SAFETY_SETTING",
  // "resolution": RESOLUTION, // Veo 3 models only
  "sampleCount": RESPONSE_COUNT,
  "seed": SEED_NUMBER
}
```
  - ASPECT_RATIO: Optional: A string value that describes the aspect ratio of the generated videos. You can use the following values:
    - "16:9" for landscape
    - "9:16" for portrait
    The default value is "16:9"
  - NEGATIVE_PROMPT: Optional: A string value that describes content that you want to prevent the model from generating.
  - PERSON_SAFETY_SETTING: Optional: A string value that controls the safety setting for generating people or face generation. You can use the following values:
    - "allow_adult": Only allow generation of adult people and faces.
    - "disallow": Doesn't generate people or faces.
    The default value is "allow_adult".
  - RESOLUTION: Optional: A string value that controls the resolution of the generated video. Supported by Veo 3 models only. You can use the following values:
    - "720p"
    - "1080p"
    The default value is "720p".
  - RESPONSE_COUNT: Optional. An integer value that describes the number of videos to generate. The accepted range of values is 1-4.
  - SEED_NUMBER: Optional. An uint32 value that the model uses to generate deterministic videos. Specifying a seed number with your request without changing other parameters guides the model to produce the same videos. The accepted range of values is 0-4294967295.
