# Iris

### Model Overview

**Iris** is a face focused enhancement model designed to recover facial detail in low to medium quality footage. It is optimized for footage where faces are degraded due to noise, compression, or interlacing.

Iris performs best on challenging sources such as archival material, broadcast footage, or heavily compressed video.

### Key Capabilities

* Specialized face recovery for older or degraded footage
* Works with both progressive and interlaced sources
* This model has been specifically trained for low quality (**LQ**) and mid quality (**MQ**) input videos.
