# Topaz Hyperion 2.5

> SDR-to-HDR video, including AI-generated footage

<CardGroup cols={1}>
  <Card title="Try Topaz Hyperion 2.5 in the Workbench" icon="flask" href="https://www.oxen.ai/ai/workbench?model=topazlabs-hyperion-2-5-video">
    Run this model interactively, tune parameters, and compare outputs.
  </Card>
</CardGroup>

**Model ID:** `topazlabs-hyperion-2-5-video`

Topaz Hyperion 2.5 converts 8-bit AI video into true HDR: an SDR-to-HDR model that redistributes luminance and color across highlights, midtones, and shadows while preserving fine detail, with no tuning parameters to set. AI footage can finally sit alongside live action in professional and VFX pipelines.

It handles AI-generated footage as well as camera source, taking 8-bit input up to professional deliverables. Output is HDR in the BT.2020 color space with a PQ (SMPTE-2084) transfer function, delivered as 10-bit H.265, 10-bit ProRes, or 16-bit lossless FFV1 for mastering, grading, and VFX workflows.

## Example request

<Tip>
  Use the [Workbench](https://www.oxen.ai/ai/workbench?model=topazlabs-hyperion-2-5-video) as a request builder: configure parameters for this model in the UI, then open the **API** tab to copy the exact cURL or Python call.
</Tip>

<Tabs>
  <Tab title="Sync">
    This blocks until the video is ready (typically 5-15 minutes). Prefer **Async** or **Async with SSE** for anything beyond quick experimentation.

    See the [video generation reference](/inference-api/reference/video_generation) for more details.
