iMovie is a versatile, all‑in‑one editor that lets you add clear, engaging narration without leaving the app. Whether you’re new to video production or a seasoned editor, this guide shows you how to record voiceovers on both macOS and iOS, and explores AI‑powered alternatives when you want a polished, professional finish.
Adding a Voiceover on iPhone
iMovie ships with iOS, so you can start creating audio right from your device. Follow these steps:
1. Launch iMovie and Open Your Project
Open iMovie on your iPhone, tap “Create a Project,” and select the video you wish to edit. If you’re starting fresh, simply choose “Movie” and import your clips.
2. Enable Voiceover Recording
Move the playhead to the point where you want the narration to begin. Tap the + icon to reveal the Voiceover menu. A recording control panel will appear above the timeline; press the red Record button to start.
3. Finish and Accept Your Recording
When you’re done, tap Stop. iMovie will present four options: Cancel, Retake, Review, and Accept. Choose Accept if you’re satisfied, or Retake to try again.
Adding a Voiceover on Mac
On macOS, the process is similar but with a few interface differences.
1. Import Your Footage
Open iMovie, click the project you want to edit, and drag the clip into the timeline.
2. Record Your Voiceover
Position the playhead at the start point, then click the Record button in the top left of the window. Speak clearly into your Mac’s microphone.
3. Stop and Save
Press the Stop button when finished. The audio clip appears on the timeline. Click Done to embed it in your project.
