Tik Tok, I have encountered the problem of how to match background music with video before, and this problem is easy to solve. Next, I'll tell you how to operate:

Tools: OPPOReno8, Tik Tok 24.7.0.

The first step is to open Tik Tok and find the plus button. (as shown in the figure below)

Step 2: Click the plus button and select Upload. (as shown in the figure below)

Step 3, then select the picture or video you want to upload in the upload interface. (as shown in the figure below)

Step 4: Click Change Music Option, select music, and then click Apply. (as shown in the figure below)

These are all the steps to solve how Tik Tok matches the background music with the video. If it's useful to you, remember to like it for me ~
