Hello, I'm glad to answer your questions. When adding music, one is to download music and the other is to use the music already in your computer. The following steps are listed:

1. When you add your own music, drag the material you just recorded into the editing library, click on the play material, there is a music option at the bottom, and then there is an insert music on the right. After clicking, there is a background music editor, select the MP3 music you inserted, and select the time period you want to insert music at the bottom, and then click Save to confirm

2. When you download music, there is a Baidu music at the editing video music. Click to enter the webpage, find the song you want to choose, click the name of the song, and then a small screen will appear with many websites on it. Right-click the top website, click Save Target as, fill in the song name, and then "download" it, and then insert and import it into the edited video.
