Slow motion is a popular special effect that can add drama and excitement to your videos. People use slow motion to build suspense, show step-by-step details, or change the mood of a situation. With so many ways to use slow-motion effects, it’s useful to know how to create a slow-motion scene right from your phone. This article explores the basics of slow motion, explains how to create a slow-motion video, and explores PowerDirector – the best video editing app – for making slow-motion edits.

What Is Slow Motion?

Slow motion has been around since the early 1900s, shortly after motion pictures were invented. As soon as people figured out how to capture moving images, they started finding ways to add special effects, like slow motion. Initially, the slow-motion effect was created by filming with a high-speed camera.

PowerDirector — The Best Slow Motion App for iPhone and Android


As an all-in-one video editing app, PowerDirector is the perfect tool for adding slow-motion effects to your videos. It offers a user-friendly interface that’s easy to navigate, so even complete beginners can start adding slow motion to their clips. But even though PowerDirector is beginner-friendly, it provides professional results. After adding the slow-motion effect to your video, you can change the speed and other settings to your own custom preferences.

How to Make a Video Slow Motion

With modern editing tools, you can produce a slow-motion video on your phone. After capturing footage with your phone’s camera or downloading a clip to edit, follow these basic steps:

1. Download PowerDirector and Tap “New Project”


Start by downloading PowerDirector onto your device. With PowerDirector on your phone, you’ll be able to add slow motion to your video and access tons of other effects. Open the app, then click “New Project” to start working on your video.

2. Import Your Video

Browse through your phone’s video library to find the clip you want to edit. You could choose from dance videos, nature videos, reaction videos, and more. You can even download clips of your favorite shows, movies, or music videos to make dramatic fan edits. Ultimately, any video with some movement and action can work.

3. Separate the Part You Want to Slow Down


While you can add slow motion to a full video, you may only want to slow down a certain part. You can create a cinematic visual contrast by having a specific clip in slow motion and the rest at regular speed. To apply slow motion to a portion of your video, start by separating out the clip you want to slow down.

With the full video open, scroll along the video’s timeline until you find the target clip. Click at the beginning of the clip, then tap the “Split” icon to cut the clip. Then, click at the end of the clip and tap the “Split” icon again. This will separate that portion from the rest of the video, allowing you to apply certain effects to that area only. This means you can add slow motion or other effects without changing the rest of the video.

4. Adjust the Speed


Tap on the clip you just separated out from the rest of your video. Then, click “Speed” to activate the slow-motion option. You can either speed up or slow down the clip. To achieve a slow-motion effect, simply slow down the speed to your desired rate. Consider previewing the video to make sure you’re achieving the effect you want.

5. Make Further Adjustments


Once you slow down the video, you can refine it to your liking by adjusting different aspects of the effect. When adjusting the speed of a clip, there are five different tools you can use to alter the effect:

  • Mute: The mute button removes the audio from the video. This can help create more suspense for your video or make it easier to overlay a different audio clip over your slow-motion scene.
  • Keep pitch: When you slow down or speed up a video, the pitch of your audio can decrease or increase. To keep your pitch the same as the original video, select “Speed adjustment” and “Keep audio pitch” in the settings.
  • Ease in: You can either immediately change the speed of your video, or gradually transition into the slow-motion effect. To progressively decrease the speed, simply select the clip and tap “Ease in.”
  • Ease out: Just as you can steadily decrease the speed to create a slow-motion effect, you can also slowly increase it as the clip returns to regular speed. All you have to do is select the clip and tap the “Ease out” button.
  • Frame smoother: You can also select the “Frame smoother” tool to ensure your video looks natural with the slowed-down frame rate.

Experiment with these features until you find a combination that creates your desired effect.

6. Save and Share Your Video

Finally, save your video. You can save your video to your phone, or keep working in PowerDirector to add other effects. Once you’re done, you’ll be ready to post your slow-motion video on your social media or other sites.
