BeMainStar Get the app

Swap yourself into a TikTok dance and keep the sound

Save the TikTok to your Photos (TikTok's own save option or a screen recording), open BeMainStar and pick it, trim it to the best 5 to 30 seconds, then take one selfie. The app recasts the dancer with you and keeps the choreography, the camera and the song that was in the clip. Trim tight: a 7 second hook costs 7 Stars and is usually the part people rewatch. The result has no watermark, so you can post it back to TikTok. A subscription is needed to start.

Why BeMainStar: The song is the trend. BeMainStar keeps the clip's audio, so your version still matches the sound.

Trim to the part you want. 6 seconds costs 6 Stars.

Step by step

  1. Save the dance. Use TikTok's save option if the creator allows it, or record your screen. Only use videos you are allowed to repost.
  2. Pick it in BeMainStar. It opens your Photos.
  3. Trim to the hook. Most trends live in 6 to 10 seconds. The trim screen shows the seconds and the Stars as you drag.
  4. Selfie. One live selfie, good light.
  5. Post. Save the video and upload it to TikTok as your own post. Say it is AI-made; TikTok has an AI-generated content label for that.

Why trimming matters

Stars are seconds, so a tight trim costs less. It also tends to look better: one continuous move is easier to recast cleanly than 30 seconds with five camera cuts. The sound you keep is the sound inside the trimmed part, so start the trim on the beat.

Want the whole squad in it?

If the trend is a group dance, BeMainStar can recast up to 4 dancers. See dance video with friends.

Price, plainly

A subscription is needed to start: Weekly is $4.99 with 5 Stars each week, Yearly is $89.99 with 8 Stars each month. 1 Star is 1 second of video, and Star packs of 5, 12 or 25 Stars top you up. Prices vary by country. If a video fails, your Stars come back.
