It’s easy to sync videos to a sound on TikTok, and here’s how to do it:
Launch TikTok.
Find a video with the sound you’d like in the background of your video.
At the bottom of the screen, click the sound, then click Use this sound.
Then tap the Upload button and choose the videos you’d like to appear in the montage (the number of videos you’ll need will depend on the sound you chose).
Once you’ve chosen the correct amount of videos, tap Next.
Ensure Sound sync is selected (underneath the video) to line up your videos with the sound.
Tap Next, then make any additional edits you want to.
Tap Next again and you can upload your video as normal.
