NOVA: Sparse Control, Dense Synthesis for Pair-Free Video Editing

CVPR 2026

GitHub

teaser

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 for installation, inference, training, and the interactive Gradio demo.
