Part 1. 4K 30fps Brief Introduction

4K: 4K Resolution means that the horizontal pixels of screen display are 4,000 pixels. There are several different kinds of 4K resolutions. In digital television, computer monitors, video games and other consumer media, 4K UHD or UHD-1 is the dominant 4K standard. It has a resolution of 3840 × 2160 pixels (2160p). In the cinema movie and video production industry, Digital Cinema Initiatives (DCI 4K) is the dominant 4K standard. It has a resolution of 4096 × 2160 pixels. YouTube have adopted UHD-1 as their 4K standard.

FPS (Frame Rate): Short for frames per second, consists of a number of consecutive scan images that are displayed on the screen each second. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the frame frequency, or be expressed in hertz.

4K 30fps video is recorded in 4K resolution (3840 × 2160 pixels or 4096 × 2160 pixels) and 30 image frames per second. iPhone 6S/6S Plus or later support recording videos in 4K 30fps.

Best 4K 30fps Cameras

There are many 4K cameras which can record 4K 30fps videos. Top 4K 30fps cameras include:

GoPro Hero5 Black, Sony FDR-X3000, GoPro Hero5 Session, Olympus TG-Tracker, Kodak Pixpro SP360, Yi 4K Action Camera, 360fly 4K, Ricoh WG-M2, Garmin Virb Ultra 30, TomTom Bandit Action Camera, Haip Waterproof WiFi Ultra-HD 4K Action Sports Camera, Sony FDR-X1000V 4K Action Cam, AEE S71 4K Sports Camera, HX-A500E-K 4K Action Camera, Kodak SP 360 4K Camera, EZVIZ FIVE PLUS Action Camera, 4K 30fps, F60 4K 30fps 16MP WiFi Action Sports Camera, Elephone REXSO Explorer X Action Camera 4K 30fps HD, Xiaomi Mijia Camera Mini 4K 30fps Action Camera 7 Glass Lens Six-axis, etc.

4K 30fps File Size

If you record a video in 4K resolution at 30fps with your iPhone, depending on the length of the video, below is how much space it will take up:

• 30 seconds of 4K at 30FPS takes approximately 175MB
• 1 minute takes up 375MB
• 5 minutes takes up 1.75GB
• 10 minutes takes up 3.5GB
• 30 minutes takes up 10.5GB

Tip: iOS 11 and newer versions use HEVC/H.265 instead of H.264 codec for videos, which will save half the amount of storage space of your device. Therefore, 1 minute 4K 30fps video using HEVC in iOS 11 takes up about 170MB.

4K 30fps vs 1080p 60fps vs 4K 60fps

Normally the higher the video resolution is, the larger the video file size is. 4K video is significantly larger than 1080p video. A one minute 1080p HD video at 60fps takes up 200MB of space, while the 4K video at 30fps will take up 375MB of space. The iPhone 8, 8 Plus, and iPhone X also support shooting in 4K in 60fps now. If you turn on HEVC to save your storage, then shooting a 60 seconds video in 4K at 60fps takes up 400MB.

File size is an important thing to consider when deciding whether to shoot at 1080p or 4K. If you want to record something fast-paced like a race or a dance routine, your best bet is to use 1080p 60fps. The higher frame rate will provide a much smoother video and higher quality. As for low light conditions, 1080p is also recommended, since recording in 4K has more pixels but smaller diodes which will affect low-light video recording performance.

Part 2. How to Enable 4K Video Recording on iPhone

Since shooting a 1-minute video in 4K at 30fps can consume 300-400 MB of storage when using H.264 codec (170MB using HEVC codec), so unless you have a large storage iPhone like 256GB iPhone, you may not turn on 4K video recording.

To turn on 4K, you can go to iPhone Settings -> Camera -> Record Video -> Tap 4K at 30 fps or 4K at 60 fps to enable 4K.
