iMovie stands out as an excellent video editor for the Apple ecosystem, making it a go-to choice for Apple users seeking powerful yet accessible editing tools.

What's more, iMovie is cross-compatible across MacOS and iOS so you can edit videos seamlessly across multiple Apple devices with iMovie.

But the best part about iMovie?

It's totally free!

Among the many challenges of video editing, an important feature is the ability to manipulate video speed, i.e., to speed up a video or slow it down based on your artistic or technical requirements.

iMovie excels in this regard: it lets you easily adjust the normal speed of your footage to create slow-motion sequences or fast-moving clips to captivate, energize, or otherwise enhance the impact of your video clips.

In this guide, we'll take you through how to speed up and slow down video using iMovie with step-by-step instructions.

We'll start by first considering iOS devices and then move to Macs.

How to Speed Up (or Slow Down) a Video on iPhone or iPad Using iMovie

It's easy to use the iMovie app on iOS devices to enhance your video clips by adjusting their speed.

I'll demonstrate how to do this in the following using an iPad with version 3.0.3 of the iMovie app (some details may differ when you try this, depending on your device and iMovie version, but the process should be similar).

Here's a quick summary:

In iMovie on your iPad, open the app and select or import your video clip. Tap the clip in the timeline to edit. Access speed controls by tapping the timer icon at the bottom. Adjust speed by dragging the slider right to speed up or left to slow down. Preview and fine-tune your changes, then tap Done to apply.

Let's now look at this in more detail, step-by-step:

  • Step 1: Open iMovie

    Launch the iMovie app on your iPhone or iPad. Locate the iMovie icon on your home screen and tap it to open.

  • Step 2: Create or Open Your Project

    Create a new project or import an existing one containing the video clips you want to edit.

    Tap on the Movie icon if starting a new project and select Create Movie.

    Otherwise tap the menu icon (i.e., the three dots) in the top-right corner of your iMovie window and select Import Project to choose the project you wish to import.

  • Step 3: Create or Import Your Video Clip

    To import your video clip, select the + icon in the top-right corner of your iMovie window and navigate to where your video files are located in your device's library. Then select the one you want.

    Alternatively, use the camera option to create a new video using your device and import it to iMovie as described above.

  • Step 4: Select Your Video Clip

    Once you've imported your video, tap on the video clip within the timeline at the bottom of the screen. This selects the entire clip for editing and prepares it for adjustments.

  • Step 5: Access Speed Controls

    To change video speed on your clip, locate and tap the speed button at the bottom of the screen. This icon resembles a timer and gives you access to iMovie's speed adjustment tools.

  • Step 6: Adjust Speed

    Drag the speed slider to the right to speed up a video or to the left to slow it down.

    You can also select from preset speed increments by tapping the 'hare' icon (to increase speed, e.g., 1+1/4, 1+1/2, 1+3/4, etc., of the original speed) or the 'tortoise' icon (to reduce speed, e.g., to 4/5, 2/3, 1/2 etc., of the original speed).

  • Step 7: Preview and Fine-Tune

    You can preview your video clip by tapping the play button. This allows you to review your speed adjustments and fine-tune them until you're happy with the speed changes that you've made.

  • Step 8: Apply Changes and Export

    Once you're satisfied with your changes, tap Done to apply the changes to your video.

    To save or share your edited video, tap the Share/Export button.

    iMovie gives you several export options to choose from with different resolution and format settings.

    And there you have it! You've just adjusted your video speed quickly and easily using iMovie.

    TIP: Trim, edit, or refine your video clips further using the iMovie app's versatile editing tools before or after adjusting their speed.
    TIP :Enhance the visual appeal of your videos using iMovie's additional features like filters, transitions, and titles.

How to Adjust the Speed of Video Clips Using iMovie on Mac

When you're using iMovie on a Mac, it's a similar process for changing video speed but with some adjustments for MacOS over iOS.

Here's a quick summary of how to speed up a video in iMovie using a Mac:

In iMovie on your Mac, select the video clip in your timeline. Click the Speed button to access controls. Choose Slow or Fast from the Speed menu and adjust using the speed buttons to set your desired playback speed.

Let's now look at how to do this in more detail, step-by-step:

    Click on your imported video clip to add it to the timeline for editing. This prepares it for you to change its video speed.

  • Step 5: Access Speed Controls

    Above the preview window, locate and click on the speed icon to access iMovie's speed controls. This control allows you to adjust your video speed.

  • Step 6: Adjust Speed

    You can choose a preset option from the speed drop-down box, such as Slow (10%, 25%, 50%, or Auto), Fast (2x, 4x, 8x, or 20x), or Freeze Frame (with adjustable Duration) to change your playback speed instantly.

    Otherwise, you can select Custom and input the percentage of your choice to fine-tune your speed adjustments.

  • Step 7: Preview and Fine-Tune

    You can view your video clip in the preview region of the video editing panel to review your speed changes.

    Play your video back to check if the altered video meets your requirements. If not, repeat the process and adjust the speed further until you're happy with the results.

  • Step 8: Apply Changes and Export

    Once you're happy with your changes, click on the speed icon again to set your speed choice. This finalizes the speed change that you've made.

    To save or share your edited video, locate the Share button located in the top-right corner of the iMovie window. Choose your preferred export settings, including format, resolution, quality, compression type, and file location, then click the button to begin the process.
