Ever filmed a clip that looked amazing, but only to realize it plays way too fast? You try to rewatch that perfect jump, dance, or slow walk, but it flashes by before you can appreciate the moment.
Most iPhone users may face this exact frustration:
How to slow down a normal video, not just one shot in Slow Motion mode? 🤔
This guide walks you through three built-in iPhone methods: Photos, iMovie, and Slow Motion recording.
And besides these, the final mysterious one is a smarter AI method that makes slow motion to another level.
Slow Down a Video on iPhone with Built-in Methods
1. Camera App — Record in Slo-Mo Mode
The easiest way to capture smooth slow motion is to record directly in Slow Motion.
Steps:
- Open Camera on your iPhone.
- Swipe modes until SLO-MO appears above the red shutter button.
- Tap the double-arrow icon to switch between front and rear cameras.
- Tap the red record button to start, then tap again to stop.
- Tap the thumbnail in the lower-left corner to preview.
- Tap Edit, then drag the speed slider to adjust which parts stay slow; tap Done to save.
💡 Tip: Shooting at 120 fps or 240 fps yields smoother motion but larger files and requires more light.
2. Photos App: Adjust Slo-Mo Segments
If your clip was shot in SLO-MO mode, you can fine-tune which part plays in slow motion directly in Photos.
Steps:
- Open Photos → Albums → Media Types → Slo-mo.
- Choose your video and tap Edit.
- Below the timeline, wide bars represent slow motion, dense bars mean normal speed.
- Drag the two tall white markers to define where the slow motion starts and ends.
- Tap Done to save.
💡 Tip: This works only for SLO-MO recordings, not normal videos.
3. iMovie App: Slow Down Regular-Speed Videos
For normal clips, iMovie gives you full control over playback speed.
Steps:
- Launch iMovie, tap Continue if prompted.
- Tap Create Project → Movie, choose your clip, then tap Create Movie.
- On the timeline, select your video and tap the Speed icon (speedometer).
- Drag the yellow slider left to slow down (up to ⅛ speed) or right to speed up (up to 2×).
- Tap Play to preview, then Done → Share to save.
💡 Tip: In Project Settings, toggle “Speed changes pitch” if you want the sound to follow speed changes.
