How to Get iPhone 5s Slo-Mo Videos Working in iMovie

The iPhone 5s comes with a neat and exclusive way to shoot videos. Users are able to shoot at 120 frames per second, which when played back, gives you a nifty slow motion effect. Unfortunately, though, when you transfer the video to your computer and open it up in iMovie, it doesn’t playback in slow motion. However, it still retains its 120 frames per second that you shot it in, so it can still be played in slow motion, but how do you that?

There’s an easy way to get your video back to playing in slow motion in iMovie, and all it takes is a quick adjustment to the video. Luckily, when you transfer the photo to your computer, it’ll playback just fine in QuickTime (but maybe not in third-party players). However, once you import it into iMovie, it doesn’t keep the slow motion, but here’s how to change that so you can get Slo-Mo back in iMovie.

iMovie Slo-Mo Troubles

When you import your slo-mo video into iMovie, it’ll recognize it as a slo-mo video and will see that you recorded it on your iPhone 5s using the slo-mo setting, but it won’t play it back in slo-mo. However, all you have to do is drag and drop the video into your project timeline in iMovie, and then go up to the toolbar and navigate to Modify >¬†Slow Motion > 25%.

This will slow down the movie to the same rate that it was originally playing back at on your phone and in QuickTime. The reason 25% is the option to choose is that the slo-mo feature on the iPhone 5s plays back these videos at a quarter of the speed of real time. Using this trick in iMovie also allows you to select certain parts of the video and only apply slow motion to that region, making it easy to slow down the parts of the video that are fast-moving and the regular parts can be played back in real time.

Furthermore, you don’t necessarily have to choose the 25% option. There’s also 10% and 50% speeds to choose from. 50% will simply just slow down your movie to 60 frames per second, and it’ll be twice as fast what the original slo-mo video plays at. Choosing 10% will slow down the video immensely, and since the frame rates don’t go that high, it’ll be a little choppy, so we wouldn’t recommend choosing 10% if you care about the quality of your video.
