1. How to Speed Up iPhone Video (Slow-mo) on Photos App

Sometimes watching a slo-mo video is boring, especially when you are in a rush or simply there is no need to have your video in slow-mo. But how do we exactly speed up videos on iPhone? It is not a difficult task since you do not have to download or install any additional application. By using the built-in feature on your iPhone’s Photos app, you can quickly speed up your video just by tapping away. Here’s how you do it.

Steps on How to Speed Up iPhone Video (Slow-mo) on Photos App:

Step 1On your iPhone, open the Photos app, then scroll down to select the Albums tab. After that, select the Slow-mo folder to access your slow-mo videos.

Step 2Tap the slow-mo video that you want to speed up, then tap the Edit on the top-right corner of the interface.

Step 3On the bottom of the screen, the video timeline is displayed as a series of vertical lines. Just drag those lines until the sections of the video are close together and narrowed.

Note that the sections of the video that are filmed in standard time are represented by lines that are close together. The video's slow-motion section contains widely separated lines as well as slightly larger end caps that indicate where the slow-motion filming starts and ends.

Step 4Lastly, press the Play button to see the sped-up version of the video, then tap Done in the top-right corner of the screen to save it.

Besides the iPhone photos app, you can also use some third-party applications from App Store.
