How to Change Slow Motion Video Recording Speed on iPhone

When we see slow-motion shots in music videos and movies, we like those and wish to capture the same. Luckily the robust iPhone in your pockets allows you to capture slo-mo videos like any regular video from the Camera app. On top of that, you can change the FPS recording speed for slow-motion video on your iPhone and have them in superior quality or higher frame rates. Let me show you how you can do it!

How to Change Slo-Mo Video Recording Speed from iPhone Settings App

  1. Launch the Settings app on your iPhone, scroll down, and tap on Camera.
  2. Tap on Record Slo-mo.
  3. Choose the desired option. 1080p at 240 fps is the highest available quality for slow-motion videos on iPhone. 240 fps video will play slower than 120 fps.Inside Settings Tap on Camera Record Slo-mo to Change Quality and fps

And that’s it! when you return to the iPhone Camera app, you will have the Slo-Mo recording speed set accordingly.


  • Under Settings app → Camera → Formats, if High Efficiency is selected, you will see only two options in step 3 above, which is 1080p HD at 120 fps and 1080p HD at 240 fps. If Most Compatible is selected, you see an additional option 720p HD at 240 fps.
  • These settings are also dependent on which iPhone model you have. For example, the iPhone 6s only has two options for Slo-mo – 1080p HD at 120 fps and 720p HD at 240 fps.
