You have just recorded a video on your iPhone, and it has captured exactly what you wanted. The scene, elements, lighting, and the narrative everything look in tip-top shape. And yet, something feels amiss. The speed may seem slow, and you don’t want to bore your friends and family who will watch the video. Take advantage of iMovie and the Photos app on your phone for speeding up the video in a matter of seconds.

Before moving forward, make sure you make a copy of the video if it is of importance and cannot be recreated. Better be safe than sorry later.

How to Speed Up a Slo-Mo Video with Photos App

You are scrolling through the Photos app and come across a video that has been recorded using the slow-mo app. In hindsight, it occurs to you that a normal video could do better. That’s not a problem, and you do not need to use iMovie either. The Photos app is capable of doing basic editing, including speeding up a video.

Let’s see how you can normalize or speed up your slo-mo video shot on your iPhone. Remember, this method might not work on the videos that you took from other devices.

Step 1. Open Photos App and Click “Edit”

Head to the Photos app and find your video. Tap on the Edit button at the top.

Step 3. Drag and Join the Progress Bar

Drag and join them in the middle to altogether remove the slo-mo effect from your video. The bars should be equally distributed after joining them. Move them towards each other in equal proportion for the desired result.

Finally, once everything looks tidied up, we save the video by tapping on the Done button located at the bottom right corner.
