Way 1: How to Speed up a Slow-mo Video on iPhone

The Slow-mo feature embedded in the Camera app allows users to record slow-motion videos directly. iOS's Photos app can convert slow-motion videos to normal speed on iPhone without extra software.

Step 1Run the Photos app from your home screen, open the Slo-mo album, and select the desired video.

Step 2Tap the Edit button and you will see the video with the speed indicator. Drag the vertical bar on one end of the Slo-mo section until all lines become close together.

Step 3Press the Play icon and preview the result. Finally, tap the Done button to save the video at normal speed.

Note: Whenever you change your mind and want to slow down the video speed, tap the Edit button, press the Revert option, and choose Revert to Original.

Way 2: How to Make a Video Fast Motion on iPhone with iMovie

The Photos app can only convert a slow-mo video recorded by the Camera app to normal speed. If you intend to speed up a regular video on iPhone, iMovie is available. It allows you to adjust video speed between 24FPS/25FPS/30FPS/60FPS.

Step 1Start the built-in video editor on your iPhone, tap the + icon to create a new project. Then choose Movie on the New Project screen.

Step 2Press the Media option, choose Video, and select the target video from Camara Roll. Tap Create Movie to put the video on the timeline.

Step 3Tap the Speedometer icon at the bottom to display the speed control bar. The turtle icon means slow-mo while the rabbit icon indicates speed-up. Drag the bar to the rabbit side to make a video fast motion on your iPhone. The video speed displays next to the speed control bar.
