### Model Overview

Hyperion 2.5 is our newest SDR-to-HDR conversion model, designed to produce richer HDR results with improved color handling, tonal separation, highlight detail, and overall clarity.

It automatically redistributes luminance and color information across highlights, midtones, and shadows while preserving fine detail, with noticeable improvements in text, small faces, and fast motion. Hyperion 2.5 also expands the available color and luminance range, including a wider nit range, providing greater flexibility for VFX compositing, color grading, and playback on modern HDR displays.

Hyperion 2.5 is particularly well suited for converting 8-bit GenAI video into professional-quality 10-bit ProRes or 16-bit EXR formats for HDR finishing and VFX pipelines. It also supports 10-bit 4K HDR source footage, allowing even 10-bit GenAI outputs to be converted to 16-bit EXR for higher-precision compositing, grading, and finishing workflows.

### Best Use Cases

* **HDR finishing and mastering.** Professional HDR deliverables from SDR sources.
* **Color grading.** More latitude in the grade.
* **VFX compositing.** 16-bit EXR output for compositing pipelines.
* **GenAI video.** Convert 8-bit generated video to 10-bit ProRes HDR.
* **HDR displays.** Content that shines on modern HDR screens.

### Model Parameters

Model parameters go inside the filter object in `filters`.

| Parameter | Type     | Required / Default | Accepted values | Description |
| --------- | -------- | ------------------ | --------------- | ----------- |
| `model`   | `string` | Required           | `"hyp-2.5"`     | —           |

Hyperion 2.5 has no model-specific parameters.

For request parameters shared by every video model (source, output, destination, and notifications), see Request Parameters. The full schema is also available in our API Reference page.

### Model Pricing

**Hyperion 2.5** is priced per output frame. Credits = ceil(output frames ÷ frames per credit).

### Example Request

{% tabs %}
{% tab title="cURL" %}

```bash
curl -X POST "https://api.topazlabs.com/video/express" \
  -H "X-API-Key: $TOPAZ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

    "filters": [ { "model": "hyp-2.5" } ],
    "output": { "resolution": { "width": 1920, "height": 1080 } }
  }'
```

{% endtab %}

{% tab title="JavaScript" %}

```javascript
const payload = {
  "source": {
    "container": "mp4"
  },
  "filters": [
    {
      "model": "hyp-2.5"
    }
  ],
  "output": {
    "resolution": {
      "width": 1920,
      "height": 1080
    }
  }
};

const response = await fetch("https://api.topazlabs.com/video/express", {
  method: 'POST',
  headers: {
    'X-API-Key': process.env.TOPAZ_API_KEY,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify(payload),
});

if (!response.ok) {
  throw new Error(`Request failed: ${response.status} ${await response.text()}`);
}

console.log(await response.json());
```

{% endtab %}

{% tab title="Python" %}

```python
import os
import requests

payload = {'source': {'container': 'mp4'},
 'filters': [{'model': 'hyp-2.5'}],
 'output': {'resolution': {'width': 1920, 'height': 1080}}}

response = requests.post(
    "https://api.topazlabs.com/video/express",
    headers={"X-API-Key": os.environ["TOPAZ_API_KEY"]},
    json=payload,
)
response.raise_for_status()
print(response.json())
```

{% endtab %}
{% endtabs %}

### Limitations

Through the API, 16-bit half-float EXR output is BT.2020 Linear; ACES2065-1 EXR export is available in Topaz Video on the desktop only. HDR improvements are only visible on an HDR display. SDR-to-HDR models don't upscale.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developer.topazlabs.com/video-models/other-utilities/hyperion-2.5.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
