5. Drag the two tall white bars to the left or right to control when the slo-mo begins and ends.
6. In the bottom-right corner, tap Done.

Tip: Slowing down the video will make the file larger. If you would like to share this video, please be aware of the maximum file size limit for sending.

3. Record Video With Slow Motion

iPhone's Slow-mo feature records videos at high frame rates so that when you play them back, they appear slower than usual.

This allows you to create amazing slow-motion effects without manually adjusting the video speed. You can also use this mode to capture beautiful moments at slow speeds.

Steps:

1. Launch the Camera app from the home screen of your iPhone. If you don't see it, swipe left on the home screen, type "camera" in the search bar, and tap the Camera option.
2. Swipe to the left to choose SLO-MO. This should be done on the tabs right above the red shutter button at the bottom of the screen. SLOW-MO is enabled when the text is yellow and suitable next to the red button.

3. Choose a camera to record (iPhone 11 and 12 only). If you have an iPhone 11 or 12, tap the two curved arrows in the bottom-right corner to switch to the front (selfie) camera. Other iPhones can only use the back camera to record in slow motion.

5. To stop recording, press the red shutter button. This saves your slow-motion video to your camera roll.
6. You can watch your recording by tapping the thumbnail in the lower left corner. Your new slow-motion video will automatically begin playing.
