Originally created in the early 2000s by the Japanese state broadcaster NHK, 8K technology stands for eight megapixels per line.
The resolution of 8K is 7680 x 4320 pixels, which is four times higher than 4K resolution.
You might be wondering, what are the benefits of 8K? Read on to find out! Until next time, happy pixeling!
8000 pixels per line
Eight thousand pixels per line is one of the highest resolutions available in video, and it is four times higher than 4K. Its horizontal resolution is around 8,000 pixels per line, and it produces a much sharper image than previous resolutions.
As of early 2019, the first 8K devices have been introduced, most likely at the Consumer Electronics Show (CES) in Las Vegas. Regardless of what type of device you buy, 8K is a step up from the current Ultra HD resolution.
To understand what an 8K television can display, you must first understand what it is. An 8K television displays 33,177,600 pixels horizontally on its display. That’s roughly four times as many pixels as a 4K television.
But don’t get carried away with the number. Eight thousand pixels per line in 8K is actually a significant increase over four thousand pixels per line, which makes it easier to understand why the resolution is so high.
The resolution of a 16K television is eight times higher than a 1080p television. While 16K is more than twice as high, it’s still not a full eight thousand pixels per line.
Thankfully, the SMPTE consortium has standardized the format and defined the ST 2082-12 standard, which describes the quad-link 12G-SDI transport method. This format uses a two-sample interleaving scheme to break down the eight-k picture into four 4K sub-images, and each 1080p sub-image is muxed into a 12G-SDI container.
3840 x 2160 pixels (4K UHDTV)
The 4K UHD television standard was born out of the requirements for the highest quality digital cinema, where content is displayed at a resolution of 4096 x 2160 pixels. However, manufacturers prefer to call the format UHD rather than 4K.
The difference in pixel breakdown between 4K and HDTV is primarily due to the larger number of pixels. A higher pixel breakdown means more detail and vivid colors, and a higher frame rate.
The four-k designation refers to the resolution of a display at a horizontal height of 4,000 pixels. In contrast, the lower-resolution 1080p has a resolution of only 3.8K, which is 8.85 megapixels. This makes the 4K resolution nearly five times higher than that of HD, which is referred to as “Ultra HD.”
The newer 4K resolution is the highest quality yet. The aspect ratio of 4K is 16:9. The resolution is also four times higher than that of Full HD. In addition, the resolution of the four-k TV is almost double that of the previous HDTV standard, or “2160p.” This newer resolution has more pixels, which makes it a better choice for high-definition television.
What are the differences between 4K UHDTV and 8K UHDTV? This technology has been the subject of intense debate for years. Although each resolution varies slightly, they are all extremely high-definition. UHDTV displays have a resolution of four thousand pixels on the horizontal and a resolution of eight thousand pixels on the vertical. By comparison, 1080p resolution has only one megapixel, while 8K resolution is sixteen times higher.
4K vs 8K resolutions
The first question you should ask is: What’s the difference between 4K and 8K resolutions? The two are closely related to the quality of the image produced, but there are a few differences that make the distinction less obvious. Resolution refers to the number of individual frames that are displayed per second.
Frame rate is a widely used technical term in video production and is believed to give a more natural motion experience.
In general, higher frame rates mean sharper images. However, unless you are watching a film in 8K, you won’t notice a significant difference.
The first major difference between 4K and 8K resolutions comes down to how you play games. While 8k gaming offers the highest resolution, the most common limitation is the frame rate. A newer 8k TV can only play games in 8k at 60Hz.
Consequently, it may be better for you to choose a 4K TV that supports HDMI 2.1. This way, you’ll be able to take advantage of 8k gaming on a 4K television with HDMI 2.1.
8K is the future of video resolutions. It’s a decade ahead of its time, and currently, only high-end display devices and cameras can support it. 8K is far more detailed than 4K and has 16 times the resolution of 1080P.
Many people are skeptical about the 8K technology, wondering why it is coming to the market so soon. Others worry that the technology will overwhelm the public.
While the difference in pixels is clear, the benefits of 8K are less apparent than those of 4K. The difference in resolution isn’t immediately noticeable, and the difference between 4K and 8K is most apparent when viewing native 8k content on an 8K TV. While this is the future of the TV industry, it’s important to note that 4K is still the most widely available resolution. So, the decision is yours.
Cameras with 8K resolutions
Eight-Kilopixel (or 8K) resolutions allow for unprecedented detail and sharpness. This type of high-resolution footage is ideal for reframing during the editing phase of the production. Because of the high pixel count, 8K footage can be shot at an extremely high bit rate. This means that the video will be more stable and less prone to jagged edges than lower-resolution footage.
Besides taking 8K video, some of these cameras can also shoot still pictures. While most 8K models can record footage at 60 frames per second, bit rates vary widely. Make sure the camera’s storage system supports the incoming speeds. Cameras with 8K resolutions also have the potential to capture 2K ProRes video. Buying an 8K camera will cost you around $3,000.
While 8K resolution means higher quality photos and videos, it isn’t necessarily better. There are a number of other factors that determine the overall video quality.
Several factors determine the quality of a picture, including the camera’s lens, the videographer’s skill, and the resolution of the recording device.
Nonetheless, 8K video is best enjoyed on a device that can record 8K video. While 8K cameras were once exclusive for professionals, their high-resolution capabilities are now available to everyday consumers.
While 8K resolution is a high-tech trend, many companies are still developing the technology needed to produce it.
Some companies are introducing cameras with 8K resolutions as early as 2020. Some manufacturers are already making 8K cameras for filmmakers, while others are focused on video operators.
For those in need of an 8K camera, consider purchasing the more expensive models. If you don’t need them right away, you may want to choose a less expensive model instead.
Frame rate of 8K video
Previously, 8K technology was only intended for large format displays. Today, however, it is supported in some high-end smartphones. The high-resolution format is associated with several features including High Dynamic Range colorimetry and high frame rate.
An 8K feed at 60 frames per second contains 2 billion pixels, and this new format presents new challenges in capture and transport.
SDI interfacing norms have also evolved to 12Gbps, but 8K video capture and transmission will require an entirely new approach.
The benefits of 8K video include enhanced details and quality. The higher the resolution, the cleaner the image, and you can zoom in and out of the picture without losing pixel information.
However, 8K requires a large amount of data on your hard drive, which will lead to longer loading times. In addition, 8K video is overkill for a number of scenarios, and you may never be able to watch it in full.
The processing requirements for 8K video are significantly higher than FHD. It is expected to need up to 128GB of bandwidth compared to the same resolution in 4K.
Additionally, 8K requires parallel processing between inline and application processors, a process that will impact local video interfaces and DDR memory.
Mezzanine compression can help mitigate these challenges. Further research on 8K video should focus on the parallelism requirements of future video resolutions.
Conclusion
Embedded applications usually implement video tasks in fixed-function ASIC blocks, and these can easily exceed the frame rate of the content.
Therefore, multiple instructions are required for each pixel.
Hence, AI is becoming an integral part of the video processing function.
Ultimately, the next phase of 8K video will be a common consumer interface for large format displays.
This new technology is expected to support 8K video at a higher frame rate and HDR via a single HDMI cable.
