Adding the trend sound so it lines up with the video

Updated: October 29, 2026

Short answer

Second by second the video mirrors the viral clip, yet its audio is a separate AI-made instrumental, not the trending sound. Take the silent file, tap Add sound in TikTok, select the sound used on the post we follow and start it at 0 seconds.

Why it lines up

The structure comes from the viral clip itself: a dip first, head swings through the middle, a grin at the end. Since our video is its first 15 seconds, nothing has to be trimmed.

If it drifts

Confirm the sound begins at second 0.
Download the silent version so two tracks do not fight, and a stray AI voice cannot sneak in.
If it is still off, shift the sound a few frames in your editor.

How to add the original sound in TikTok

Your video comes with an AI-made soundtrack. If you would rather use the trending sound, add it inside TikTok when you post. You can also save a copy without sound from My videos (Download without sound) and put the original sound on that.

Open this clip in TikTok: our video follows it. Tap the sound name at the bottom, then tap Use this sound.
Tap Upload and pick the video you downloaded from us.
Open Volume and turn the video's own sound down to 0, or use the Download without sound copy from My videos.
To line up the beat, use the scissors (trim) so the sound starts at 0 seconds, then post.
