First we must convert audio files in MP3 format into video files in MP4 format. We find a small picture at random and pull it into the clip together with the MP3 audio file.
Aligning the track lengths of images and audio is a basic operation of video editing, so I won’t go into details. Then modify the video size, select Custom, and change it to smallest. The smallest size allowed for editing is 64:64.
After making the changes, export the video. Then open Douyin Live Companion, click "Add Material" on the left, and select "Video" in the pop-up box.
Import the video, it will automatically pop up the "Video Settings" dialog box, check "Loop Play".
Then pull the video down to a corner and hide it.
The above is the relevant content about how to add music to Douyin Live Companion. I hope it will be helpful to you!
