How to Sync Video and Audio in iMovie

If you’re trying to figure out how to sync audio and video in iMovie, there’s two ways to do it:

  1. There’s the EASY way, like using an app called Woowave DreamSync that handles all the synchronization for you.
  2. Then there’s the MANUAL way.

In this post, we’re going to show you how to sync your footage the MANUAL way.

Here’s a breakdown from YouTube tutorial expert Matthew Pearce, who tells us how to make this process as simple as possible inside of iMovie.

Getting Back to iMovie Basics:

Before getting started; we highly encourage you to download the “iMovie- Getting Started” 4-Step Checklist.
It will help you speed up the editing process for every one of your videos.

Got your 4-step checklist?

Great. Now, let’s move on…

Using iMovie to Sync Your Video and Sound Files

Here we are in iMovie with some footage that was shot with on a Canon 70D. (My personal favorite DSLR camera to shoot with these days.)

We’re using this setup (shown below) where the timeline is located at the bottom of iMovie. 
If you’re using the more traditional setup, it doesn’t really matter, this is just a personal preference.


The first step is to bring in our audio. We can easily do this by dragging and dropping the sound clip into our timeline.

The next step is to turn on the audio waveforms. (This step is crucial!) 

We can do this by clicking on the button in the bottom right.
From there, You’ll suddenly see exactly what’s going on with your audio in the timeline.




Manual Clip Alignment

I like to clap 3 times before I start recording my videos. This makes it super easy to find the audio peaks and match them to my video content when I’m looking at the audio timeline. 

As you can see in the screenshot below, this makes the spikes in my audio easy to line up when we are syncing the audio and video together in iMovie.

The next step is to simply bring our audio clip over and line it up with the video clip’s audio spikes.


The final step is simply to turn down the audio from camera in our original timeline. (see screenshot)


Once the original (crappy) audio from the camera is turned down, all we’re going to hear is our newly synced external audio with our video footage.

That’s it! Now our audio OFFICIALLY sounds more professional than 99% of all videos created in iMovie.
