牛小影

NiUXiaoYing (牛小影), previously known as Niuxuezhang Video RepAIr Tool, is a desktop utility focused on Cleaning up and improving existing video footage rather than creating new CLIps. It combines several AI models inside a single interface so users can pick the processing APProach that best matches the problem in their footage, whether that is low resolution, noise, damage, or a low frame rate.

What it does

The core workflow is straightforward: load a video file, choose a model, and let the software render an improved veRSIon. The tool handles upscaling from low-resolution sources toward 4K or 8K ouTPUt, repairs files that fail to play or play erratically, and reduces visual noise. It also includes specialized models rather than a single General-purpose filter, which helps when a video contains faces, animation, or night scenes.

Key capabilities

• Upscaling: Raises resolution on older or low-quality clips, aiming for 4k or 8k results depending on source material and hardware.
• Repair: Attempts to fix corrupted or unplayable files and unstable playback issues.
• Portrait restoration: Detects faces and rebuilds facial detail in human-centric footage.
• Black-and-white colorization: Adds estimated color to monochrome footage, which can suit archival or family material.
• Animation model: Targets jaggies, noise, and streaking common in cartoons and anime.
• Frame interpolation: Raises frame rates to smooth motion and reduce stutter.
• Night enhancement: Lifts brightness and contrast in dark footage.
• Sky replacement: Uses AI to generate and swap the sky background in a scene.

Who it is for

The tool suits home users restoring family recordings, editors cleaning up shaky or poorly lit phone footage, archivists working with old films and television material, and animation fans repairing older cartoon episodes. Because the model list is opinionated and scene-specific, it is most useful to people who can trial a few options and compare results, rather than to users seeking a single one-click fix for every clip.

How to get started

Download the Windows client from the official site, install it, and open a supported video file. Select a model category that matches the footage type, preview the result, then export. Processing heavy 4K or 8K output can take significant time and benefits from a capable GPU and sufficient disk space.

Pricing and access caveat

Availability of free functions, trial exports, and paid tiers may vary and could change; check the official page for current licensing and watermark policies before committing to a purchase. The software is aimed at Chinese-speaking Windows users, and English localization may be limited or absent.
