What is the automatic FPS in the iPhone camera?

On some older iPhones, you get a feature called “Auto Low Light FPS,” which automatically reduces the video frame rate to 24 fps to adjust exposure in low light. This happens when you move from a bright environment to a dim environment while recording video.

Auto-FPS is an enhanced version of the same.When enabled, it will automatically reduce the frame rate to 24 fps to improve low light video When needed.Furthermore, it is based on scene movement. If it is a high dynamic scene, your iPhone will automatically switch to a high frame rate.

Record video on iPhone

While the iPhone XR, XS, XS Max, iPhone 11 and iPhone SE (2nd generation)the new Auto FPS feature is available on the following iPhones:

  • iPhone 12, iPhone 12 Mini, iPhone 12 Pro, iPhone 12 Pro Max
  • iPhone 13, iPhone 13 Mini, iPhone 13 Pro, iPhone 13 Pro Max
  • iPhone SE (third generation)

Turn Auto FPS On or Off on iPhone

Recording video at 24 fps keeps the shutter open for longer when shooting in dark areas. This causes the camera to capture more light. On the other hand, for scenes with lots of fast motion, it’s best to record at 60 fps to capture smooth video.

With Auto FPS, iOS does this intelligently by automatically increasing or decreasing the frame rate as required by lighting and scene motion. So you can get better low-light videos with optimized file size.

Here’s how to enable or disable automatic FPS on iPhone 12, iPhone 13, and iPhone SE 2022:

1. Open set up on your iPhone.

2. scroll down and click camera.

3. here, click Record video.

4. scroll down and click car FPS.

5. Here you can choose between the following options:

  • leave: Turn off automatic FPS
  • Auto 30 fps: Only applies Auto FPS to 30fps video.
  • Auto 30 and 60 fps: Apply automatic FPS to 30 and 60 fps videos.

Select if you want Auto FPS to work only when you are shooting in 30 fps mode Auto 30 fps. This will ensure that the iPhone maintains a constant refresh rate in video without any adjustments in 60 fps mode.

But if you want automatic frame rate to work for all settings, select Automatic 30 and 60 fps.

Should you record in auto FPS mode?

When recording in auto FPS mode, the iPhone automatically switched from 60 fps to 24 fps when I moved from a well-lit area to a dark room. And because the shutter is open longer, it can record bright video with visible detail.

Conversely, with Auto FPS turned off, 60 fps video looked smooth, but nothing could be seen in the dark. So if your main purpose is to shoot bright video with detail in low light, keep Auto FPS turned on. But if you want 60 fps smoothness, it’s best to turn it off anyway.

The change in frame rate happens during the video. You’ll notice a transition as you move from bright to dark areas. When the frame rate is reduced, the smooth picture is slightly choppy.

To check if the video is switched to a lower frame rate you can use EXIF Data Viewer application on the iPhone. Install the app, allow it to access photos, and choose to turn on automatic FPS recording of videos. Scroll down and check Frame Rate under Video.

In our case, a 60 fps video recorded with AutoFPS showed a frame rate of 33.33. However, the frame rate recorded without the feature enabled appears to be 59.96.

Here are other tips you can follow to record brighter video in low light with your iPhone:

  • Using LED flash: You can turn on the flashlight on the back to add extra light to the scene. But it only helps with close objects.
