How to add background music to a video on desktop

For projects requiring deep customization, the desktop version is superior. Movavi Video Editor serves as a versatile video background music changer for all users. It offers a stable environment for editing long-form content. You can explore a vast sound effects library within the app. You can even remove background noise to sharpen your voiceovers. The interface stays clean while offering advanced professional tools.

Step 1. Install and prepare your workspace

Run the downloaded setup file and follow the clear prompts. Launch the editor once the installation finishes. Click Add Files to bring in your media. Your clips will appear in the Project files. Drag the files onto the timeline: videos will be added on the Video track and audio files will appear on the Audio track.

Step 2. Add background music to the video

Sometimes the music outlasts the visuals. Move the red marker to the end of the video. Use the Scissors icon to split the audio track. Delete the excess part to keep things tidy. To cover a longer video, simply copy and paste the track. If the music feels too abrupt, apply fade in and fade out audio effects.
