# Starlight Precise 1

### Model Overview

**Starlight Precise 1** is the original diffusion-based video enhancement model and the first of its kind designed specifically for video. Originally developed as Project Starlight, it was created to enhance footage previously considered impossible to restore, including degraded film and low resolution GenAI video.

Precise 1 is a generative diffusion model that intelligently improves detail, temporal consistency, and structure while preserving artistic intent, performing all enhancement automatically without manual controls.

### Key Capabilities

* First ever diffusion model purpose built for video enhancement
* Transforms degraded, low resolution footage into clean, consistent HD or 4K results
* High quality, automatic enhancement with no sliders or manual tuning required
