If you are constantly shooting videos on your iPhone to get that perfect shot for Instagram Reel or YouTube Shorts, you can easily relate to it. You might need to speed up the video to fit within the story, or simply reduce its size to transfer. 

Regardless of your reason, you can actually achieve it on your iOS device. In this article, we are going to discuss how to speed up a video on iPhone. So, without further due, let’s jump right into it. 

Top 3 Ways to Speed Up Video on iPhone

This goes without saying that the stock Photos app can easily handle basic photo and video editing on the go. But, there are certain limitations to it, especially when it comes to speeding up any normal video.

In this section, we are going to discuss some of the most common ways in which you can achieve the same on your iPhone.

1. Speed Up Slo-Mo Videos Using Photos App

There are instances where you might want to simply bring back your slo-mo videos to normal speed. Thankfully, you can change the same without using any third-party application whatsoever. So, here’s how you can speed up videos using the Photos app: 

Step 1: Head over to the Photos app on your iPhone and pick the slo-mo video you want to speed up. From the top right corner, tap on ‘Edit’.

Step 2: You will find the speed indicator right below the timeline. The parallel lines which are closed together indicate normal speed, while the lines with spaces are for slow-motion parts. 

Step 3: Try dragging the vertical bar, so that the vertical lines are closer to one another. 

Step 4: Once you have adjusted the speed of the video, simply tap on ‘Done’. 

This is by far one of the most seamless ways in which you can speed up any slo-mo video on your iPhone. In case you ever make up your mind to revert back, tap on ‘Edit’ and select ‘Revert’ from the bottom right corner. Now, tap on ‘Revert to Original.’ 

2. Speed Up Your Videos Using iMovie 

Bear in mind that the Photos app is only limited to speeding up slo-mo videos, but can’t be used to speed up any normal video. This is where you can use Apple’s iMovie app to speed up any normal videos on your iPhone. You can follow the steps mentioned below: 

Step 1: At first, download and install iMovie from the Apple App Store. Launch iMovie on your iPhone and tap on ‘+’ to start a new project. 

Step 2: Once the ‘New Page’ screen appears, click on Movie. From the top left corner, tap on Media

Step 3: Tap on Video and select the folder to locate your video. Even in iMovie, you can speed up your slo-mo video similar to Photos. 

Step 4: Tap on the video you want to edit and select ‘Create Movie’ from the bottom of the window. 

Step 5: Once your project opens in iMovie, you can tap on the video clip and access all the editing options. From the bottom of the timeline, tap on the speed editor (with a clock icon) and change the speed of the video accordingly. 

Note: To toggle the range, you can drag the yellow range handle accordingly. Tap on Add within the inspector to create an additional range. 

Step 6: You can find the speed control given by a turtle icon on the left followed by a rabbit icon on the right. This way, you can change the speed of your video from left to right. 

Note: If you have made any mistake and want to start over, tap on the Reset button from the inspector. 

Step 7: Once you have edited the video, tap on Save to make changes. 

Note: iMovie preserves the pitch of the audio while making changes to the speed. You can change this from the Project Settings button, and turn on the ‘Speed changes pitch’ option. This way, the voice will be modulated based on the speed of the video.
