What is a TikTok duet?

A TikTok duet is a feature that allows you to create a new video next to an existing one. The original video plays on one side of the screen, while your recorded response or addition appears on the other. This creates a split-screen effect that lets creators react, collaborate, or expand on content in real time. TikTok duet videos are widely used in challenges, commentaries, and community trends. They also offer a direct way to engage with popular content and creators. The format supports creativity while riding the momentum of viral videos.

How to do duet on TikTok the right way

To duet on TikTok, you open a video, tap the share icon, and select “Duet.” But the process goes deeper if you want results. The right setup, format, and execution help your duet land on the TikTok FYP. The TikTok duet feature lets you record your own video alongside someone else’s. You might react to a funny clip, add your input to a challenge, or use another video as context.

Before you record, make sure your app is up to date. Then follow this:

1. Open the TikTok app and find the video you want to duet.
   
2. Tap the “Share” icon on the right side of the screen.
   
3. Choose the “Duet” option.
