  2. 2. Why is it called 8K Resolution?

1. What is 8K Resolution?

To start with, let's begin with the basics: what is 8K resolution? The resolution of a video depicts the amount of detail that a video holds. Video resolution is measured in terms of the number of pixels in a frame. 8K resolution means approximately eight thousand pixels are running in a single horizontal line across a frame (7680 x 4320 pixels in a single frame, to be exact).

8K resolution is the successor of 4K resolution, meaning that it offers almost 4 times the details and quality of the standard 4K. Although this level of precision is not usually noticeable on ordinary devices, specific 8K TVs can help you see the difference.

2. Why is it called 8K Resolution?

The reason behind the name "8K" is that the video frames are almost eight thousand pixels wide. Due to its immensely detailed quality, 8K is often referred to as full ultra-high definition (known as ultra-high definition television). Some manufacturers also call it the 8K Super Hi-Vision.

3. Where will 8K content come from?

Although 8K TVs are available for use, 8K content is rarely seen. Owing to YouTube's new AV1 codec, you can find actual 8K content on the streaming site. Besides YouTube, the only other streaming service offering real 8K content is Vimeo. All other labels, such as Netflix, Amazon Prime Video, or Disney+, are not currently supporting 8K, even on demand.

The seemingly minor support for 8K content is primarily due to the high cost of 8K-compatible cameras and devices. Besides, 8K content is extremely large in size and requires impeccably fast storage drives.

Resolution Comparison: 1080p vs. 4K vs. 8K

8K resolution is still relatively new, but 4K and 1080p resolutions have been around for quite some time. For those of you wondering about the differences among these resolutions, here is a detailed comparison(Quick navigation is provided as well, which helps you save your time):

  1. 1. Resolution
  2. 2. Video Size
  3. 3. Video Quality
  4. 4. Content Availability
  5. 5. Viewing Angle

1. Resolution

The 1080p resolution offers 1920 x 1080 pixels per frame. In comparison, 4K offers almost four thousand pixels, which can vary according to the type and manufacturer. The largest number of pixels on a screen is provided by the 8K resolution of 7680 x 4320, which is 4 times the 4K Ultra HD resolution.

2. Video Size

The size of the video varies directly in accordance with the resolution. A one-minute recording of full HD 1080p at 30fps requires 130MBs, Ultra HD 4K at 30fps requires 375 MBs, and full UHD 8K requires 600MBs.

3. Video Quality

Similar to the video size, higher resolutions mean higher video quality for users. As the amount of pixels in a frame increases, more detail is captured, thus increasing the overall quality. 8K resolution provides the best quality by far, followed by 4K, and then 1080p.

4. Content Availability

1080p resolution has become a standard for most cameras and videos, also seen in the original PS4 and Xbox One. The 4K Ultra HD has also become quite common in everyday use, and 4K content can be found everywhere, including on popular streaming sites. In contrast, 8K content is still emerging as part of a new line and can only be found on some sites.

5. Viewing Angle:

8K resolution supports a 100-degree horizontal viewing angle, whereas 4K comes with a 55-degree angle. The 1080p resolution offers the least optimum viewing angle of 40 degrees.

Where Does 8K Resolution Make Sense Today?

Almost all major manufacturing companies are shipping 8K TVs, including Samsung and LG. Although 8K content is currently very scarce, it still holds a bright future. While major streaming platforms such as YouTube and Vimeo are already supporting codecs for 8K files, other major labels are not far behind.

The latest Xbox and PlayStation series are ready to unlock the support for 8K resolution. As the resolution gains more popularity, it is bound to see a rise in content and demand. Besides gaming and videos, 8K resolution also has applications in large-scale businesses, research, and museums are also looking to expand their horizon.

Final Verdict

Now that you know what is 8K resolution and where to find 8K content, you can decide if you want to invest in it or not. Although some key differences separate 8K from its predecessors, the distinction is not always clear on low-resolution devices. 8K resolution holds tremendous potential for the future and can undoubtedly revolutionize modern cinema.
