How to Speed Up a Video on iPhone & Android

Speeding up a video used to be something you could only do on very powerful computers. But now, all you need is a smartphone to create clean, professional-quality videos at whatever speed best fits your project. Continue reading to learn how to speed up a video on iPhone or Android, the best apps to use, and some cool effects you can add to tweak your project.


Why Do We Want to Speed Up a Video?

Speeding up a video can add an interesting effect to a project. For instance, it’s good for:

  • Making repetitive or simple segments pass quicker
  • Making sure the production focuses on the more interesting parts of the video without totally cutting out the other content
  • Ensuring the video matches the desired length of either the project as a whole or a selection of music or other audio

How to Speed Up a Video with PowerDirector

Whether you want to learn how to speed up video on iPhone or Android, you can rely on PowerDirector to get the job done.

1. Download PowerDirector to Adjust Speed For Your Video

To get started on how to speed up a video on iPhone or Android, your first step is to download PowerDirector. You can find it for free in the Apple App Store or Google Play. Because the app is free, all you have to do is search for it, tap download, and follow the on-screen instructions.

2. Select Video Clips to Speed Up a Video in Your Project

Choose the video clips you want to adjust by importing them from your device’s photo and video library. Before the app will allow you to import videos, you need to grant it access to the video library on your device. Once you've given the app access, you can navigate to the video you'd like, tap its thumbnail, and import it.

3. Open the Tool Bar and Tap "Speed" to Speed Up a Video on the Phone

PowerDirector has a primary track that's up top and can also provide multiple tracks underneath it, but to change the speed, you have to tap the primary track. After tapping it, you can choose the "Speed" option at the bottom of your screen.

Note: Tapping any of the tracks underneath the primary one brings up different choices, and changing the speed isn't one of the options.

4. Adjust Speed for Your Video

On your screen, you will see a slider appear on the right. To adjust how fast the video plays, all you have to do is move the slider up or down. To make the video speed up, move the slider up, and to make it slow down, bring the slider down. As you move the slider, it tells you the ratio at which you're boosting or reducing the video's speed.

5. Select Detailed Functions to Speed Up a Video on the Phone

You can choose from a few different options to change what happens to your video once the speed is adjusted:

  • Keep Pitch. This maintains the pitch of the video even though the speed is different
  • Ease in. Ease in gives you a transition into the sped-up section of the video
  • Ease out. Ease out provides a smooth transition from the end of the sped-up video to the next segment of your project.

6. Produce & Share Your Video After You Speed It Up

After the video’s speed has been adjusted to your liking, you can produce it, which involves rendering it in its new, sped-up form. You can also share it using your preferred method. To do this, you have to click the icon in the upper right corner of the screen—an open box with an arrow pointing out of the top. You can then choose to share it on Instagram, YouTube, or Facebook.
