# Topaz Labs Starlight Precise 2.5

Starlight Precise 2.5 is a diffusion-based video enhancement model from Topaz Labs that upscales, denoises, de-aliases, and sharpens video while maintaining full temporal consistency across frames. It delivers photorealistic detail with natural skin textures and faces, preserving the original look of the footage without artificial artifacts.

### [deliveryMethod](https://runware.ai/docs/models/topazlabs-starlight-precise-2-5#request-deliverymethod)

- **Type**: `string`
- **Default**: `async`

Determines how the API delivers task results.

**Allowed values**:

### [uploadEndpoint](https://runware.ai/docs/models/topazlabs-starlight-precise-2-5#request-uploadendpoint)

- **Type**: `string`
- **Format**: `URI`

Specifies a URL where the generated content will be automatically uploaded using the HTTP PUT method. The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials.

**Common use cases:**

- **Cloud storage**: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs.
- **CDN integration**: Upload to content delivery networks for immediate distribution.

```text
// S3 presigned URL for secure upload
https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600

// Google Cloud Storage presigned URL
https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789

// Custom storage endpoint
https://storage.example.com/uploads/generated-image.jpg
```

The content data will be sent as the request body to the specified URL when generation is complete.

### [ttl](https://runware.ai/docs/models/topazlabs-starlight-precise-2-5#request-ttl)

- **Type**: `integer`
- **Min**: `60`

Time-to-live (TTL) in seconds for generated content. Only applies when `outputType` is `URL`.

### [includeCost](https://runware.ai/docs/models/topazlabs-starlight-precise-2-5#request-includecost)

- **Type**: `boolean`
- **Default**: `false`

Include task cost in the response.

**Inputs**

Input resources for the task (images, audio, etc). These must be nested inside the \`inputs\` object.

### [video](https://runware.ai/docs/models/topazlabs-starlight-precise-2-5#request-inputs-video)

- **Path**: `inputs.video`
- **Type**: `string`
- **Required**: true
