Quickly apply or replace audio across multiple video files without opening them one by one. With Batch Audio Overlay, you can streamline your workflow and keep everything organized.
1. Select Your Files
- Go to the file manager.
- Hold Ctrl (or Cmd on Mac) and click to select all the video files you want to overlay.

3. Assign New Output Tags
To tag your new files:

- The newly added tag will be set as the primary tag by default. You can change this by clicking the thumb icon next to the tag.
4. Configure Audio Settings
Loop Audio: Repeat the music to match the length of the video (prevents silent parts).
Keep the Audio in Input Video: If enabled, original video audio will play together with the selected music. Uncheck this to replace the original audio completely.
Shuffle Audio Tracks: If you select multiple audio files, enabling this will randomize the playback order. Each video will have a different sequence of background music.
