How to speed up slow-motion video on your iPhone to normal speed

Now you have already recorded a video in slow-motion and if you wish to bring it back to the normal speed you can use the photos app to nullify the slow-motion. The disadvantage with slow-motion in the iPhone is it does not give much control over the speed settings for the video, we can only get videos of one speed, let us see the steps to do it. 

  •  Launch the Photos app on your phone.
  • Tap on the Albums at the bottom of the screen to see the types of photos and videos present in the Photos app.
  • Now click on “Slo-Mo” to see the slow-motion videos list you have on your phone’s storage.
  • Choose the video you want to speed up and click on edit at the top of the screen.
  • We can see the editing timeline at the bottom of the screen, it will be represented by a series of dashes, if the dashes are closely spaced, that represent a normal video, and dashes that do not represent the slow motion video. The dashes are also larger for the Slow-Motion video clips.
  • Now to bring back the speed to normal, we will have to drag the bars on the timeline to speed up the video.
  • Hold the bar at one end and drag it to the bar at the other to disappear from the slow-motion section of the video.
  • Tap on done to save the video at full speed.
