Have you ever wanted to slow down a video on your iPhone to capture every detail in slow motion? Well, you’re in luck!

In this tutorial, we’ll show you how to easily slow down a video on your iPhone using the built-in features of iOS. Let’s get started!

Step 1: Open the Photos App

First, open the Photos app on your iPhone. This app is represented by an icon that looks like a color wheel and should be located on your home screen. Tap on it to open.

Step 2: Select the Video

Once you’re in the Photos app, navigate to the album or folder where your desired video is located. Tap on it to select it.


If you don’t have the video saved in your Photos app, you can import it from other apps or transfer it from your computer using iTunes or other file-sharing methods.

Step 3: Tap Edit

After selecting the video, tap on the “Edit” button located at the top-right corner of the screen. It looks like three horizontal lines with circles on them.

Step 4: Adjust Speed

In edit mode, you’ll see a timeline at the bottom of your screen that represents different frames of your video. At each end of this timeline, there are two sliders labeled “Start” and “End”. Drag these sliders inward to select a specific portion of your video that you want to slow down.


If you want to apply slow motion effects to the entire video, skip step 4 and proceed directly to step 5.

Substep A: Select Speed Option

Once you have selected the portion of your video, tap on the “Speed” button located above the timeline. It looks like a speedometer.

Substep B: Choose Slow Motion

In the Speed options menu, you’ll find different speed presets for your video. Tap on the “Slow Mo” option to apply a slow-motion effect to your selected portion of the video.

Step 5: Save and Export

After applying the slow-motion effect, tap on the “Done” button to save your changes. You’ll be taken back to the main editing screen where you can further adjust other elements of your video if desired.


You can also add additional effects, filters, or crop your video in this editing screen before saving and exporting it.

Step 6: Export and Share

Once you’re satisfied with your edited slow-motion video, tap on the “Done” button again. You’ll then be prompted with multiple export options such as “Save Video” or “Share”. Choose the option that suits your needs best.


The export options may vary depending on whether you want to save it locally on your iPhone or share it via social media platforms or other apps.


You’ve successfully learned how to slow down a video on your iPhone using built-in features of iOS. Now go ahead and capture stunning slow-motion videos with ease!

  • Tips:
  • If you want to speed up a video instead, follow these steps but choose the “Speed Up” option instead of “Slow Mo”.
  • The Photos app offers basic editing features; for advanced editing, you may consider using third-party apps from the App Store.
