Last Updated on October 10, 2020 by Robert Jackson


When creating a video for How-to, commentary, presentation, or dubbing on Mac, you can use iMovie, the powerful video editing tool on Mac computers, to trim the video and add audio to it. iMovie has a built-in Voice-over feature that allows users to add a narration to the video. In this tutorial, I will walk you through the details of how to record a voice-over on iMovie.

Add Audio on iMovie

1. How to record a voice-over on iMovie

Since most Mac screens are pre-installed with a microphone device, you don’t need to insert an extra one unless you’re looking forward to higher audio quality.

Step 1 Open Voiceover

On your iMovie, click the Import button and add your movie to iMovie. Then, click the icon of Record Voiceover.

Click the big red button of Start Recording.

After a 3-second countdown, iMovie will start to run your video clip and the Voiceover is on the run. You may follow the playback and speak to your microphone.

When you finish adding voice, click Stop Recording.

Step 3 Preview and adjust the audio

To adjust and preview the audio, you need to click Done first. Next, you can click Start to preview the video along with the voiceover.

You can locate your voiceover in Timeline and drag it to reposition it.

To set the fade-in and fade-out effect for your voiceover, you need to click on the green bar of it first. Then, click the 2 tiny pots on the bar to set a certain fading effect.

You can also adjust the playback rate of the voiceover by dragging its start/ending point to the left or right.

If you want to modify the volume of the clip, still, locate the green bar first. Then, move your cursor to the line that lies upon the middle of the bar. Click it and drag up or down to make it louder or softer.

So, this is how you can record a voiceover on your iMovie.

Tip: The Voiceover feature only captures the real-time sound through a microphone device. To record the playback like the sound from YouTube, Spotify, or some other online platforms on your Mac computer, you may switch to an iMovie alternative.

2. How to fix the ‘iMovie won’t record Voiceover’ issue

When iMovie won’t let your record a voiceover, you can try these methods to fix it.

  • Click the Voiceover Options and set the Input Source as Built-in Microphone.
  • See if you’ve set the volume in iMovie as the lowest, it this is the case, set the volume slider to higher.
  • Make sure the computer’s audio is not muted.
  • Re-launch iMovie and reimport the footage.
  • Unplug all the third-party microphone devices, including a webcam or headphone with a microphone installed.

If iMovie still fails to record a voice-over after you try all the methods, you may give up on iMovie and try another tool to record the audio.
