To take a slow motion video on an iPhone, switch the Camera app to Slo‑mo mode, set your preferred quality in Settings, then record as usual and fine‑tune the slow‑motion part in the Photos app’s editor. Modern iPhones let you both shoot directly in slow motion and convert or tweak clips afterward for a more cinematic look.

Slo‑mo basics on iPhone

  • Open the Camera app and swipe through the modes at the bottom until you see Slo‑Mo , then tap it.
  • Tap the red record button to start and stop recording; the clip saves straight into your Photos app marked as a slo‑mo video.

Set frame rate and quality

  • Go to Settings → Camera → Record Slo‑mo to choose resolution and frames per second, typically 120 fps or 240 fps depending on your model.
  • Higher fps and resolution give smoother, more dramatic slow motion but use more storage space on your iPhone.

Edit where it goes slow

  • Open the Photos app, select your slo‑mo clip, tap Edit , then use the timeline at the bottom to adjust where the video switches between normal and slow motion.
  • Drag the handles so only the key moment (like a jump, splash, or spin) plays in slow motion, then tap Done to save your changes.

Turn a normal clip into slow motion

  • You can slow down a regular-speed video using Apple’s editor or apps like iMovie: import the clip, then reduce its playback speed on the timeline.
  • This works best when the original video was shot at a higher frame rate; otherwise the footage can look choppy or blurred when slowed down.

Quick capture tips

  • Shoot in bright light so each frame is sharp; slow motion exaggerates any blur or noise in low light.
  • Aim slo‑mo at fast, detailed motion—water splashes, sports, falling leaves, or confetti tend to look especially dramatic on an iPhone in Slo‑mo mode.
