Editing a slow-motion video is incredibly simple with your iPhone slow-mo video editor. After you’ve taken your video, you can edit it in the Photos app; choose when you want the slow motion to start, when the video clip begins and ends, what filters to use, what rotation or cropping you want, and even exposure and saturation settings. Let’s get started learning how to edit slow-motion videos on the iPhone.

  6. To adjust where the video begins and ends, tap either end of the timeline and slide it left or right. A yellow outline will highlight the portion of the video you will keep.

  7. To rotate or crop a video, tap the rotate-crop icon, which looks like a box with overlapping corners and two curving arrows. This will take you to a screen offering the same rotate and crop options you're used to seeing when editing photos.

  8. To apply a filter, tap the filters icon, which looks like three overlapping circles.

  9. To manually adjust color settings such as exposure, brightness, contrast, shadows, saturation, etc. tap the dial icon.

  10. When you are finished, tap Done.

Now you can edit where your slow-mo videos start and end, as well as how to add filters, rotate them, or crop them. If you ever save changes and decide you don't like them, you can always revert an edited video back to the original. If needed, you can also crop a video on your iPhone and iPad. Happy editing!
