What Is the Size of 4K Video on iPhone per Min/Hr and How to Downsize 4K Video
4K video recording hasn’t been the exclusiveness of professional 4K camcorders since the day that iPhone 6s and iPhone SE support 4K video recording. What’s the 4K file size?
By Candice Liu ｜Last updated on July 31, 2023
Dozens of users are still bothered by the large-sized 4K video file size (4 times the pixels of 1080p) and they feel an urgent need to know the detailed file size of 1 minute or 1 hour of recording 4K ultra HD at 30FPS/60FPS on iPhone. Thus, they can easily handle the 4K video duration when recording based on the storage capability of his/her device. To address your needs, the below part will clearly show you how much space it’ll take up based on the 4K video length, video codec (H264/H265) and frame rate you adopt.

How Much Space Does iPhone 4K Video Consume at 24/30/60FPS
1 Minute of an iPhone 4K Video
- 1 minute of 4K at 24FPS will takep up 270MB for H264 and 135MB for HEVC/H265.
- 1 minute of 4K at 30FPS will take up about 350MB for H264 and 175MB for HEVC.
- 1 minute of 4K at 60FPS will take up approximately 400MB for HEVC.
1. to save iPhone space, generally Apple won’t allow you to record 4K 60FPS video on iPhone unless you turn on and use HEVC codec for 4K recording.
2. Once you upgrade your iOS 10 to iOS 11 on iPhone 7/7 Plus, the 4K video recording will be automatically running at HEVC codec to save space up to 50%.
1 Hour of an iPhone 4K Video
- 1 Hour of 4K at 24FPS takes up around 15.8GB for H264 and 7.9GB for HEVC/H265.
- 1 Hour of 4K at 30FPS consumes about 20.5GB for H264 and 10.3GB for HEVC.
- 1 Hour of 4K at 60FPS hogs up space approximately 23.4GB for HEVC.
Now, based on your iPhone space capability, you know how long of the 4K video your iPhone can store without eating up all your iPhone space. If you’re not sure about the frame rate your iPhone 4K recording supports, check the following part with specific iPhone model, 4K video frame rate and maximum 4K video length.

FAQs about 4K Video File Size
How big is a 1hour 4K video?
The file size of a 1-hour 4K video can vary depending on the compression settings and video codec used. Typically, at standard bit rates, a 1-hour 4K video can be expected to range from approximately 45 GB to 110 GB. This estimate is based on using the H.264 or HEVC (H.265) codecs with bit rates between 50 Mbps to 100 Mbps.
However, if a more efficient codec like HEVC is utilized, the file size might be on the lower end of the range due to better compression. On the other hand, if higher bit rates or less efficient codecs are used, the file size may be closer to the higher end.
How many GB is 1 minute of 4K video?
The file size of 1 minute of 4K video can vary based on several factors, including the compression settings, codec used, and bit rate. Here are approximate file size estimates for 1 minute of 4K video at different bit rates using the H.264 codec:
Low bit rate (e.g., 20 Mbps): Approximately 90 MB to 110 MB
Medium bit rate (e.g., 50 Mbps): Approximately 225 MB to 275 MB
High bit rate (e.g., 100 Mbps): Approximately 450 MB to 550 MB
If a more efficient codec like HEVC (H.265) is used, the file size might be smaller compared to the estimates provided above.
How many GB is 20 minute of 4K video?
Using the H.264 codec as an example, here are approximate file size estimates for 20 minutes of 4K video at different bit rates:
Low bit rate (e.g., 20 Mbps): Approximately 1.8 GB to 2.2 GB
Medium bit rate (e.g., 50 Mbps): Approximately 4.5 GB to 5.5 GB
High bit rate (e.g., 100 Mbps): Approximately 9 GB to 11 GB
How many GB is a 2 hour 4K movie?
Below are rough estimates, and the actual file size can be more or less depending on the specific video content and compression settings used.
Low bit rate (e.g., 20 Mbps): Approximately 180 GB to 220 GB
Medium bit rate (e.g., 50 Mbps): Approximately 450 GB to 550 GB
High bit rate (e.g., 100 Mbps): Approximately 900 GB to 1100 GB (1.1 TB)
