how to duet on tiktok

Making a TikTok video is fun. But what’s more fun is that you can create a duet video with someone else on this platform. How does TikTok Duet works? It allows users to create videos featuring an initial video and make both videos appear side by side on the screen. Users can also choose from one of the four layouts: a left and right layout, react layout, top and bottom layout, and three screen layout.

In this tutorial, you’ll learn how to duet a video on TikTok and an alternative way to make a better duet video for TikTok.
