# `generateVideo()`

Generates videos durably inside a workflow. The helper starts an asynchronous
video generation job with a Workflow webhook URL, suspends the workflow until
the provider sends a terminal notification, and then retrieves the completed
result with one status request.

Unlike [`experimental_generateVideo`](/docs/reference/ai-sdk-core/generate-video)
from `ai`, this helper does not download provider-hosted videos. URL results
remain URLs so your workflow can decide whether to persist, copy, or process
them in another step without serializing the video bytes through workflow step
boundaries.

```ts
import { experimental_generateVideo as generateVideo } from '@ai-sdk/workflow/video';

export async function videoWorkflow(prompt: string) {
  'use workflow';

  // The workflow suspends while the video renders, consuming no compute.
  const result = await generateVideo({
    model: 'klingai/kling-v3.0-t2v',
    prompt,
  });

  return result.videos;
}
```

The selected model must support asynchronous start and status operations and
provider webhooks. The helper must be called from a Workflow SDK workflow.

## Import

<Snippet
  text={`import { experimental_generateVideo as generateVideo } from "@ai-sdk/workflow/video"`}
  prompt={false}
/>

## Parameters

The helper accepts the same parameters as `experimental_startVideo` from `ai`,
except `webhookUrl` and `abortSignal`. It creates and manages the webhook URL.

## Returns

Returns the completed status result from the provider. `videos` contains raw
provider video data discriminated by `type`:

- `url`: A provider-hosted URL and media type
- `base64`: Base64-encoded video data and media type
- `binary`: A `Uint8Array` and media type

Hosted URLs can expire. Handle any video you need to retain in a separate
workflow step.
