How to Do It

Prepare the video and audio files

Start with the edited video and choose background music, narration, voiceover, or sound effects that fit the purpose.

Place audio at the right moment

Align music or narration with the video so important visuals and spoken explanations stay synchronized.

Adjust volume balance

Keep background music lower than speech and avoid sudden loud sections that distract from the video message.

Preview before final export

Listen through key moments to confirm audio starts, fades, transitions, and ending points feel natural.

When This Helps

Add music to social videos

Music can make short posts feel more complete and help set the tone before text or narration begins.

Add narration to tutorials

Voiceover helps explain steps in a tutorial without requiring the viewer to read everything on screen.

Prepare demos with clearer audio

Product demos often need narration or supporting audio so viewers understand what is happening.

Improve family or event videos

Background music can make travel, family, and event clips more watchable after trimming and joining.

Practical Questions

Can I add background music to a Mac video?

Yes. Import an audio file, place it with the video, adjust timing, and export the video with audio included.

Can I add voiceover instead of music?

Yes. Narration and voiceover are useful for tutorials, demos, lessons, and presentation videos.

How loud should background music be?

It should support the video without covering speech, captions, or important original sound.

Should I add music before or after joining clips?

Usually after joining, so the audio can match the final video length and structure.
