Slow motion videos have their own swag and if you often watch sports on TV, you have likely watched these videos before. A slow motion video, as the name implies, is a video that moves really slowly than the normal version. This gives a really great effect on whatever it is you are trying to highlight in your video.

If you want to make a slow motion video, you do not really need a long list of equipment. All that you need to create a slow motion video is just an iPhone. As long as you have a compatible model of the iPhone, you are good to create any kind of slo-mo videos you want on your device. The following post explains what exactly is a slow motion video on the iPhone camera, how you can make one, and how you can then edit it on your phone.

Part 1: What is Slow motion on iPhone Camera

From a normal point of view, a slow motion video is just a video in which everything has slowed down. However, from an iPhone and a technical point of view, things are a bit different. A normal video on an iPhone is usually played at 60 FPS meaning you see 60 frames per second on your screen.

However, in the case of a slow motion video, you are shown 120 frames per second and that gives you the feel that the video is indeed slow. Most iPhone models are compatible to record slow motion videos. The really modern models can actually shoot videos at 240 FPS.

Before you actually start recording the video, you will want to adjust a few settings on your iPhone. The following steps cover that as well for you.

Step 1. Launch the Settings app on your iPhone, scroll down, and find and tap on the option that says Photos & Camera. It will open your iPhone’s camera settings menu.

Part 4: How to Change a Normal Video to Slow Motion

Many users have this issue that they shot a video on their iPhone but they forgot to enable the slo-mo option. As a result, they got a normal video which has no slow motion effect in it at all.

If you already have a video or a bunch of videos on your iPhone that you would like to turn into slow motion videos, a free app for the iPhone can help you do it.

iMovie is a free video editing app available for both iPhone and Mac machines. You can use it to increase and decrease the speed of your video. The latter should help you transform your normal video into a slow motion one on your device.

Step 1. Head over to the App Store and download and install then iMovie app on your iPhone, if you have not already done so.

Step 2. Launch the iMovie app on your device, tap on Projects at the top, and then tap on Create Project to start a new project for your videos.

Part 5: How to Speed up or Slow Down a Slow Motion Video on iPhone

Another scenario you may come across is that you have a slow motion video that you want to slow down even more or speed it up. Both of these tasks can be done from within the Photos app on your iPhone.

You do not need iMovie to do this but it can be used to do the task if you want.

Step 1. Launch the Photos app and find and tap on the video you want to turn into a regular video.

Step 2. Tap on the edit icon at the bottom to open the iPhone’s default video editor.

Step 3. You will then see the handles you can drag to change the speed of the video. Use these to adjust the video playback speed and then save the video. Your slow motion video should now have become a normal video.
