What Is a Duet on TikTok?

Before we answer the question, “How do you Duet a video on TikTok?” We first have to define what a Duet is. 

A Duet is a TikTok editing option that allows creators to play content side-by-side. Beyond generic commentary, other uses for Duets include: 

  • Product reviews 
  • Arguments or debates 
  • Voice over content and narration 
  • Viral challenges and trends 
  • Reaction videos (verbal or non-verbal) 
  • Collaborations 
  • Reshares of previously posted content 
  • Fan engagement 

TikTok Duet vs Stitch Videos

While similar, Duets are different from a Stitch, which instead plays the first clip of content in sequence before the second clip. Duets are a popular way for creators to offer commentary to original posters (or OPs), while Stitches are more commonly used for commentary or reaction purposes only. 

Steps for How to Duet a Video on TikTok

Learning how to Duet a video on TikTok is a simple skill that can have major payoffs later. Here’s how to Duet a video in just a few simple steps.  

  1. In the TikTok app, find a video you want to Duet. You’ll want to pick an option that’s engaging and relevant to your viewers. 
  2. Click the Share button on the right side of the screen.
  3. Tap Duet. It’s located in the bottom row of icons. 
  4. Choose a Duet layout from the pop-up of options.
  5. Tap the record button to create your Duet.
  6. Tap the check mark once you’re done. 
  7. Edit your Duet as you see fit. This is a great time to add in stickers of text overlays that make your content engaging. 
  8. Tap Next. 
  9. Add a caption. It’s best to keep these short and sweet, using keywords for searchability in TikTok’s algorithm. 
  10. Tap Post.

1. Choose Which TikTok Video You Want to Duet

When you’re learning how to duet a video on TikTok, it’s important to remember to choose engaging content. Your viewers want to be immediately hooked from the first second of your video, so you’ll want to pick vibrant, well-produced, and immediately engaging content.

Scroll through your feed and select which TikTok video you want to Duet. Be sure to check and see that you actually can Duet the video based on the user’s privacy settings before progressing further.

2. Select a TikTok Duet Layout

Once you’ve selected your video to Duet, you’ll be taken to the native video editor. From there, you can choose from four predetermined TikTok Duet layouts: 

  • Normal
  • Left and right
  • React
  • Top and bottom 

Experiment and determine which one works best for your content. 

3. Add a Filter for Your Video

At the time of this publication, TikTok adds whatever effects or filters were used in the original video to your Duet. However, you can easily remove them if you don’t want them. To remove an effect, tap on Effects in the bottom left-hand corner of the editing display. Then, select from TikTok’s effects library and edit as you see fit. 

You can do the same for filters by going to the right-hand side of the screen and tapping on filters to edit. 

4. Record Your TikTok Duet

After you pre-set your filters and effects for your content, it’s time to film. You can shoot your Duet all in one take or splice different clips in seconds using TikTok’s native video editor. 

5. Edit Your Duet Video

Now, it’s time to edit your Duet. There are no “rules” for editing. However, edits made with the customer in mind are most effective. Some examples of this include relevant stickers, caption text overlays, or narrative voice over. 

Voice over is a great way to infuse some personality into your Duets. However, the TikTok native editor has limited voice over features that vary in quality and don’t feature the high-quality audio ducking and support that MixVoice does. If you want to enhance your content’s production, film, add voice over, and save your Duet video, use MixVoice voice over app.

6. Write a Caption for Your Post

Once your Duet is done, it’s time to consider a caption. TikTok functions similarly to a search engine, using keywords to put optimized, personalized content in front of its users. As you write, be sure to place keywords at the front of your caption in a natural, conversational way. You can also benefit from using them in the audio you add (if any).

It’s also best to keep captions short and sweet, allowing your viewers to immediately read and digest your content. 

7. Edit TikTok Duet Video Settings

Now, it’s time to edit your TikTok Duet settings. To get to the settings area, complete your edits and click the check mark on the bottom right-hand side as if you were to publish your content. Once you reach the next window, click More Options — the second option from the bottom of your native display. 

In this panel, you can slide-toggle your comment, Duet, Stitch, and sticker settings to personalize your content and share your authentic experience. You can also enjoy more advanced settings, allowing you to label AI-generated content (if applicable), save the video to your device, or post the video as a template. 

8. Publish Your TikTok Duet

It’s time to publish your Duet. You can choose to post immediately by clicking the red Post button at the bottom right of your screen. Or, you can choose to save your content as a draft for later by tapping Drafts at the bottom left of your screen. The choice is yours.
