AI Video Blur: How to Blur Faces and Moving Objects in Videos

Part 1: Introduction

Wondershare UniConverter 18 helps you blur faces and moving objects in videos to protect privacy and hide sensitive information. Its AI Video Blur tool offers two modes: AI Face Blur automatically detects faces for selective blurring, while Object Tracking Blur follows manually selected moving targets, such as license plates, to keep them blurred as they move.

You can customize the blur effect with different styles and settings, including Strength, Feather, and Opacity. Follow the steps below to blur faces and moving objects using UniConverter 18 on Windows.
