There are several ways to slow down a video on an iPhone:
-
Using the Photos app for videos recorded in Slo-Mo mode:
- Open the Photos app and select the Slo-Mo video.
- Tap "Edit" on the top right.
- On the timeline at bottom, drag the handles (taller white lines) to adjust where the slow-motion effect starts and ends.
- Tap "Done" to save the changes.
This method is limited to videos originally recorded in Slo-Mo mode and does not add slow motion to regular videos.
-
Using iMovie (works for any video):
- Open the iMovie app (free from the App Store if not installed).
- Create a new Movie project and import the video.
- Tap the video clip in the timeline to reveal editing options.
- Tap the Speed (speedometer) icon.
- Drag the slider left (toward the turtle) to slow down the video.
- Tap "Done" and export the video to save the slow-motion version.
iMovie provides flexible control to slow down any video, not just Slo-Mo recordings.
-
Using third-party apps like YouCam Video for more precise speed control and enhancement options.
In summary, for an easy adjustment on Slo-Mo clips, use the Photos app. For slowing down any video, iMovie is the best built-in option, or you can use dedicated video editing apps for more effects and controls.
