To get started, open your video in the Photos app and tap Edit in the upper-right corner.īelow your video in edit mode, you will see a series of tick marks. Or you can adjust the portion of the video that is slowed down. If you shoot a slow-motion video, you can return the video to regular speed. If you have a iPhone 5S, you can shoot slo-mo videos at 120 frames per second, and if you have an iPhone 6 or later, you have two slo-mo options: 120fps and 240fps. Slow-motion videos are a fun option for iPhone and iPad videographers, letting you slow down the action for dramatic effect.
