How Much Space an HD, FullHD, 4K and 8K Video Occupies on Your Mobile

Now that phones such as the Samsung Galaxy S20 or the Xiaomi Mi 10 are going to start standardizing 8K video recording, it is worth knowing how much these videos occupy on a mobile, just as we can review what takes a minute of video HD, FullHD, 4K on your smartphone.



In this image it is clear the width and height pixels offered by each type of recording and why, obviously, a minute of 8K clip will take up much more space than a FullHD clip because it contains much more information per frame / frame.

How much space does a minute / hour of video take?

HD video recording

Each minute of recording in 720p HD quality at 30 fps occupies just over 60 MB.

This means that a one-hour recording will occupy a total space of about 3.6 GB, so we can fill a smartphone with 128 GB of storage with just over 30 hours of video.

  • 1 minute recording in HD resolution = 60 MB
  • 1 hour recording in HD resolution = 3.6 GB

FullHD video recording

Although for some time we have phones capable of recording in 4K, the vast majority of recordings we make with our phones are usually made at 1080p resolution. In this sense, every minute of recording in Full HD at 30 fps about 130 MB.

This gives us a figure close to 8 GB per hour, leaving us less than 16 hours for a mobile with 128 GB memory.

  • 1 minute recording in FullHD resolution = 130 MB
  • 1 hour recording in Full HD resolution = 7.8 GB

4K video recording

Each minute of recording in 4K quality at 30 fps occupies 375 MB. If we extrapolate this data to hours it gives us a total of 22.5 GB for a one hour clip. This means that with more than 5 hours of 4K video we will completely fill the memory of a 128 GB smartphone.

  • 1 minute recording in 4K resolution = 375 MB
  • 1 hour recording in 4K resolution = 22.5 GB

8K video recording

The Galaxy S20 compresses an 8K quality video at 30 fps in a minute at 600 MB

It is from here that we have to be careful because working with a standard model of 128 GB capacity, it would be enough to accumulate just over 3 hours of video in 8K to completely fill the internal memory.

  • 1 minute recording in resolution 8K = 600 MB
  • 1 hour recording in 8K resolution = 36 GB

Aspects to consider

As you will see, we are talking about a standard recording speed of 30 fps , at normal speed. As soon as we go to work with clips in slow motion, which include more pictures per second, the size of the video will grow exponentially. For this reason if you are going to record a FullHD video at 960 fps, it can hide much more than the same clip recorded in 4K at 30 fps.

To this we must add the different AI compression technologies that many manufacturers incorporate in their camera app and that make measuring the space that a video occupies on your mobile phone more and more complicated.
