You can use Veo on Vertex AI to extend videos that you previously generated using
Veo. You can extend videos using either the Google Cloud console or
the Vertex AI API. For information about writing effective text prompts for video generation,
see the Veo prompt
guide. In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Enable the Vertex AI API.
In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Enable the Vertex AI API.
Set up authentication for your environment. Select the tab for how you plan to use the samples on this page:
When you use the Google Cloud console to access Google Cloud services and
APIs, you don't need to set up authentication.
To use the REST API samples on this page in a local development environment, you use the
credentials you provide to the gcloud CLI.
Install the Google Cloud CLI.
After installation,
initialize the Google Cloud CLI by running the following command:
If you're using an external identity provider (IdP), you must first
sign in to the gcloud CLI with your federated identity.
For more information, see
Authenticate for using REST
in the Google Cloud authentication documentation.
The following examples show how you can extend a Veo video:
In the Google Cloud console, go to the Vertex AI > Media Studio
page. Click Video to open the Video Media Studio page. In the Settings pane, configure the following settings: Model: Select Veo 2 Aspect ratio: Choose either 16:9 or 9:16. Number of results: Adjust the slider or enter a value between 1
and 4. 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. In the Write your prompt box, enter your text prompt that describes the
videos to generate. Click Hover over the video you want to extend then click >
Extend video. In the Write your prompt box, enter your text prompt that describes the
videos to generate. Click
To learn more, see the
SDK reference documentation.
Set environment variables to use the Gen AI SDK with Vertex AI:
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:
Additional optional parameters Use the following optional variables depending on your use
case. Add some or all of the following parameters in the
HTTP method and URL:
