How to Duet on TikTok
Quick answer
Tap the Share arrow on the video, tap Duet, then record your reaction while the original plays alongside you. Pick a layout before recording, then post as usual. The option only appears if the original creator allows duets on that video.
Step by step
- 1
Find the video you want to duet
The video must be public and the creator must allow duets.
- 2
Tap the Share arrow
The arrow icon is on the right side of the video.
- 3
Tap Duet
The camera opens with the original video positioned next to your recording frame.
- 4
Choose a layout
Options include side by side, green screen, and top-bottom. Pick the one that fits your reaction or commentary.
- 5
Record your side
The original video plays in sync while you record. Your audio mixes with the original unless you mute one of them.
- 6
Edit and post
Add text or effects, write a caption, and post. TikTok tags the original creator automatically.
Worth knowing
- Your own duet permissions live in Settings and privacy > Privacy > Duet, and per video in the post screen's More options.
Doing this for a brand, not just an account?
Duets let a brand join trending conversations with original commentary, which is faster than producing a standalone video from scratch.
Common questions
Why can't I duet a video on TikTok?
The creator has disabled duets for that video or their whole account, or the video is private. There is no workaround; permissions are controlled entirely by the original poster.
What is the difference between Duet and Stitch?
A duet plays the full original video next to yours at the same time. A stitch clips up to 5 seconds of the original and puts it before your own footage.
Does the original creator get notified when I duet them?
Yes, they get a notification and the duet links back to their original video. That link is why duets with larger creators can pull their audience to your profile.
