Everyone who is using an iPhone knows how to slow down videos, by either recording the video on slo-mo or by editing the video and slowing it down. However, not many people know about speeding up a video on iPhone.

If you are one of those users who don’t know how to speed up a video on an iPhone, then below we have the tutorial for you.

iPhones are pretty capable smartphones, and when it comes to video editing, you can do that on your phone easily. Your iPhone can edit and speed up your videos for you. It even works for videos that have already been recorded.

Usually, on speeding up a video, there are two factors, either you try to speed up a slo-mo video, or you try to speed up a normal video. Let’s see below how to speed up each video.

Speeding Up a Normal Video

To speed up a normal video, you need Apple’s video editing software iMovie, it is free for everyone and can be downloaded from the Apple store. In most cases, the app comes pre-downloaded on Apple devices by default, but if you don’t have it you can head to the App Store to download the app.

Once you have downloaded the iMovie app, you can follow through with the tutorial to speed up a normal video.

1. On your, iPhone open the iMovie app and then tap on the Create project.
   
2. Select the Movie from the pop-up that appears.
   
3. Next, you need to find the video that you want to speed up and then select it to import it to iMovie. Tap on Create Movie located at the bottom of the screen.
   
4. Once the video is imported, you will see the editing screen. Tap on the video timeline to see the editing options available for the video.
   
5. The video timeline should be highlighted in yellow and the editing tools should appear at the bottom of the screen. You need to tap on the Speed button which should look like a clock. Inside the speed option, you will get the playback controls.
   
6. The first tool in the speed controls will be a slider that you can use to speed up or slow down a video. iMovie can easily speed up your video up to two times its original speed.
   By default, the slider will show 1x on the right to indicate the original speed. You can drag the slider towards the right to the value you want to speed it to, if you drag it to the left, the speed will decrease.
   
7. The video can be sped up to 2x the original speed.
8. Tap on the play button to see the results of the adjusted video playback speed.
9. Once, you have adjusted the speed of the video, you can tap on the Done button located in the top left corner, and then save it once your work is complete.
10. You can save this video from the iMovie to your camera roll. You can directly share it with another app as well.

Speeding Up a Slo-mo Video

Using your iPhone, you can also speed up the videos recorded in slo-mo. Speeding up the slo-mo recorded video is even easier than speeding up the videos recorded at normal speed. When you speed up a slo-mo video, it will return to its normal speed. Follow through the tutorial below, to speed up a slo-mo video using your iPhone.

1. On your, iPhone open the Photos app and then tap on the Albums.
   
2. Next, you need to go to the slo-mo to open all the slo-mo videos on your iPhone.
3. Choose the video you want to speed up and then tap on the Edit button which should be located in the upper-right corner of the screen.
   
4. You will see the timeline of the video at the bottom of the screen. You will see a set of vertical lines, the tightly spaced lines indicate normal video, whereas the far apart lines indicate the part of the video which is in slow motion.
   
5. The part of the video which is in slow motion also has a larger line at either end. In order to speed up the video, you need to put your finger on the left line and then try to drag it to the right line.
   
6. After that you will see that the slow-motion section of lines has disappeared, this confirms that the video is now completely at normal speed, and the slo-mo part is now at 1x speed like the rest of the video.
   
7. You can tap on the Play button to check the video speed before saving it. Once you are satisfied with the video speed, you can click on done to save it to your camera roll.
   

Conclusion

The iMovie app is a very handy app for editing videos, you can apply filters, slow down a normal video, or speed up it provides a lot of options for video editing.

On the other hand, the slo-mo videos recorded from your iPhone can be edited from the Photos app itself, which gives you the ease to customize and set what part of the video should be in slo-mo and what part of the video should be in normal speed.

For all these editing you don’t need any extra hardware tool, or a computer, all you need is your iPhone and the iMovie app that’s it.
