To make a video slow motion on your iPhone after recording it, the process depends on how the video was originally recorded:
- If the video was recorded in Slo-Mo mode on your iPhone, you can use the built-in Photos app to adjust the slow-motion section:
- Open the Photos app and select the Slo-Mo video.
- Tap "Edit" in the top-right corner.
- In the video timeline at the bottom, drag the taller white vertical lines to adjust where the slow-motion effect starts and ends.
- Tap "Done" to save the changes.
- If the video was recorded in normal mode (not Slo-Mo), you cannot add a slow-motion effect using just the Photos app. Instead, use a video editing app like iMovie:
- Open iMovie on your iPhone (download it free from the App Store if not installed).
- Tap "+" to create a new project and select "Movie."
- Choose the video you want to edit and tap "Create Movie."
- Tap the video clip in the timeline, then tap the speedometer icon.
- Drag the speed slider to the left to slow down the video.
- Tap "Done," then use the share icon to save the slowed video back to your Camera Roll.
Other apps like YouCam Video, CapCut, and InShot also let you easily apply slow motion to any video with precise speed controls. These apps provide more flexibility and effects for enhancing videos beyond the built-in options. In summary, Slo-Mo mode videos can be adjusted directly in Photos, while normal videos require third-party apps like iMovie or others to create slow-motion after recording.
