How to Change Video FPS on iPhone Camera

The video camera on the iPhone is in a league of its own. It offers unmatched stability and an overall second-to-none experience. However, with a few additional settings, you can make video recordings even smoother on your iPhone. Here’s how to change the fps for video on the iPhone camera.

Increasing the frame rate per second, or the fps, can significantly improve the quality of your video recordings. However, videos with higher fps take up more storage space on your iPhone. We’ll explain everything you need to know. Let’s begin.

What Happens When You Increase FPS on iPhone Video Camera

A video recording is essentially a combination of still photos stitched together. Each still photo is referred to as a frame. An optimal number of frames must be captured and stitched together for a smooth video.

Therefore, around twenty-four to thirty frames are captured per second for a good-quality video. However, if you increase the number of frames per second – and bump it up to sixty, twice as many frames will be stitched together for a single second, resulting in smoother transitions and overall better quality.

But videos recorded in higher frame rates will occupy more storage since they carry more frames – hence more information.

Understanding Frame Rates in Slow Motion Videos

When it comes to slow-motion videos, more frames – around 120-240 – are captured per second. They are stitched together, and the video is then played at 30 fps, resulting in visuals that seem to move slowly.

For instance, if you recorded at 240 frames per second and played it back at 30 frames per second, each second of the recorded video would be stretched out across eight seconds, giving the impression of slow motion.

A 120 fps slow-motion video is the commonly used option, but to increase the slow-motion effect, you can opt for a 240 fps slow-motion video. Here’s the difference between the two.

• 120 fps: When you record at 120 frames per second (fps) and play the footage at the standard 30 fps, you achieve a 4x slow-motion effect. This means that one second of real-time action is stretched out to four seconds in the final video.
• 240 fps: Recording at 240 fps and playing back at 30 fps results in an 8x slow-motion effect. In this case, the final video stretches one second of real-time action to eight seconds.

Now that we know what happens when we increase the frame rate of the video, let us understand how to change the FPS for the video camera on iPhone and how it impacts the storage.

Increase or Decrease Frame Rate in iPhone Camera for Video Recording

Here’s how you can change FPS for the video recording on your iPhone.

Step 1: Open the Settings app.

Step 2: Scroll down and tap on camera.

Step 3: Tap on Record Video.

Step 4: Choose the option for the frame rate.

You can also see the impact of the higher frame rate on storage. Here’s what it says:

A minute of video will approximately consume:

• 60MB with 720p HD at 30 fps.
• 130MB with 1080p HD at 30 fps.
• 175MB with 1080p HD at 60 fps.
• 270MB with 4K at 24 fps.
• 350MB with 4K at 30 fps.
• 400MB with 4K at 60 fps.

Alternatively, you can also change the frame rate on the Camera app. You can tap on the frame rate button in the top right corner to change it.

Enable or Disable Auto FPS for iPhone Video Camera

When you are recording a low-light video on your iPhone, the selected fps option may not be ideal. A 30 fps setting, instead of 60 fps, is recommended for low-light environments. The shutter is kept open for a longer duration within a second (since 30 fps captures fewer frames per second than 60 fps), which results in capturing more light within the scene on your video camera.

On the other hand, while capturing videos where the scene consists of a fast-moving subject, you would ideally want smooth transitions. Therefore, 60 fps is better than 24 fps or 30 fps.

Your iPhone recognizes the scene you are trying to capture and auto-adjusts the frame rate for the ideal output. Here’s how you can enable the toggle.

Note: Auto FPS is available on iPhone 12 and newer models. You may see the option ‘Auto Low Light FPS’ if you use an older iPhone.

Step 1: Open the Settings app.

Step 2: Scroll down and tap on camera.

Step 3: Tap on Record Video.

Step 4: Scroll down and select Auto FPS.

Step 5: Select the relevant option. For best results in both low light and fast-paced scenes, we recommend selecting the ‘Auto 30 fps and Auto 60 fps’ option.

Change Frame Rate in iPhone Camera for Slo-Mo Videos

Here’s how you can change fps for the slow-motion video recording on your iPhone.

Step 1: Open the Settings app.

Step 2: Scroll down and tap on camera.

Step 4: Tap on Record slo-mo.

Step 5: Choose the frame rate setting.

You can also see how the frame rate impacts the storage occupied by the video. Here’s what you need to know:

A minute of slo-mo will approximately consume:

• 350MB with 1080p HD at 120 fps.
• 300MB with 720p HD at 240 fps.
• 480MB with 1080p HD at 240 fps.

Alternatively, you can change the frame rate using a quick toggle button in the Camera app.
