How to use TikTok's duet feature? Steps for operating TikTok Duet and React, along with popular duet tutorials

How to use TikTok's duet feature? This article provides an illustrated guide on the activation methods, operational steps, copyright compliance points, and practical operational tips for using duet and React to increase followers.

Differences and applicable scenarios between TikTok Duet and React

Duet (Synchronization): Your video is displayed side by side with the original video, with both frames playing simultaneously. It is suitable for content such as music accompaniment, dance synchronization, and dialogue. React (Reaction): Your reaction video is superimposed on the original video in a picture-in-picture format, suitable for content such as movie reviews, game reactions, and commentary. Each has its own characteristics; Duet is more suitable for interactive collaboration, while React is more suitable for expressing opinions and emotions.

Preparations before using Duet: Confirm that the original video has enabled the duet permission

Not all videos support Duet and React. Some creators may disable the duet function due to copyright protection or personal preference. If a video supports Duet, you will see the "Duet" option below after clicking the share button (the curved arrow icon); if it is disabled, the option will not appear or you will be prompted with "This video does not allow duet." Music, dance, and dialogue videos usually have a higher open rate.

Breakdown of Duet Synchronization Operation Steps

Step 1: Find a video that supports Duet, and click the share button (the curved arrow icon) in the lower right corner.

Step 2: Click the "Duet" option in the sharing menu to enter the duet recording interface. The left side of the interface displays the synchronized playback of the original video, while the right side shows your camera view.

Step 3: During the recording process, you can click to switch between the front and rear cameras, and use the filters and beauty effects available in the bottom toolbar. After recording is complete, click the checkmark to enter the editing page.

Step 4: Add text, stickers, or music to the duet video on the editing page, and then publish it. The published Duet video will display the original video author information, and clicking on the duet video will take you to the original video.

React video operation steps

React operates similarly to Duet: After finding a video that supports React, click the share button and select "React" to enter the recording interface. The original video is displayed in a small window in the corner, which can be dragged to adjust its position (four corners are selectable) and zoomed to resize the window. After recording, edit and publish it. In some versions, React is integrated into the secondary menu, including two sub-options: "React" and "React to TikTok". The latter allows continuous reactions to multiple videos.

Copyright compliance red lines and content forbidden zones for co-productions

Forbidden area 1: Videos containing unauthorized copyrighted music are likely to be muted or removed from the platform after being dubbed.

Forbidden Zone 2: Videos involving politically sensitive, violent, pornographic, and other violations may be punished by the platform, even if they are co-produced with the intention of criticism and opposition.

Forbidden Area 3: For co-production proposals with commercial purposes, it is recommended to communicate with the original author in advance to avoid infringement disputes. It is advisable to prioritize co-producing original content or content that has been authorized.

Co-production content operation tips: How to rapidly increase followers with the help of co-production

Tip 1: Give priority to videos that have already gained some popularity but have not been fully explored in the comment section, as the comment section often contains a wealth of collaborative inspiration.

Tip 2: The collaborative content should have creative interaction or form an interesting contrast with the original video, rather than simple imitation. For example, if the original video is a dance, you can add different styles of interpretation; if the original video is a product review, you can record different experiences using the same product.

Tip 3: In 2026, TikTok updated its duet recommendation logic. Duet content is no longer only pushed to the original video creator's followers. It is also pushed to other users interested in the topic based on the quality and interactivity of the duet content, providing creators with greater exposure opportunities. It is recommended to actively interact with viewers in the comment section after posting to guide the direction of discussion.
