If you’ve ever watched a YouTube video where someone reacts to a viral clip, reviews a trailer, or breaks down a piece of content with their face in one corner and the video playing beside them, you’re watching a reaction video.

In this tutorial, I’ll walk you through how to make your own reaction video—the easy way.

What Is a Reaction Video?

A reaction video is exactly what it sounds like: you’re reacting to a video while watching it. These are popular across YouTube, TikTok, and even inside online courses. Whether you’re critiquing a presentation, reviewing content, or just adding your own commentary, reaction videos are a powerful format to engage viewers.

But here’s the good news—you don’t need complicated editing software or hours of post-production.

The Setup: Record Your Webcam and Screen at the Same Time

To create a smooth, professional-looking reaction video, you need just a few essentials:

• Your webcam (built-in or external)

• The video or screen you want to react to

• A reliable app that lets you record both at once

In my latest YouTube video, I’ll show you step-by-step how to set this up, pause and play the video while recording, and create the kind of layout that YouTube viewers love.

Why This Setup Works

This workflow is perfect for:

• YouTube creators who want a polished look

And the best part? You don’t have to do any editing afterward. Just hit record, react, and you’re done.
