## Overview

NOVA is a pair-free video editing model built on **WAN 1.3B Fun InP**. It uses sparse keyframe control (e.g., a single edited first frame) to guide dense video synthesis, trained without requiring paired before/after video data.

- **Pair-free training** via degradation simulation
- **Sparse keyframe control**: provide one or more edited keyframes
- **Optional coarse mask** for improved editing accuracy

## Usage

See the [GitHub repository](https://github.com/WeChatCV/NovaEdit) for installation, inference, training, and the interactive Gradio demo.
