# Nyx

### Model Overview

**Nyx** is a high-quality video denoising model designed to reduce noise and grain while preserving fine detail and natural texture. It is optimized for camera-based footage, especially content affected by sensor noise, low-light conditions, or heavy compression.

Nyx focuses exclusively on noise reduction without sharpening or creative modification, making it ideal for clean preprocessing or standalone denoising workflows.

### Key Capabilities

* High-quality denoising with natural texture preservation
* Reduces sensor noise and grain without smearing detail
* Dedicated noise reduction without added enhancement
