Dissemination of 4K videos, how can I handle the heavy capacity?


There is one thing in common when we look at the characteristics of recently released electronic devices. It is that it is equipped with a ‘4K resolution display’. Thanks to this, the current 4K displays are rapidly becoming disseminated. In addition, YouTube, the world’s largest video platform, has high-definition standards of 4K, and the public is getting used to 4K video.

As the use of video content has soared, the video market is literally booming, and with the development of technology, the spread of 4K video can be seen as a natural phenomenon. However, this phenomenon may not be welcomed by content providers. This is due to the ‘capacity’ of the video content.

Is expensive equipment the best way to create excellent quality content?

As the demand for content increased, the supply has increased. In the midst of the abundance of content produced in a day, creators are fiercely competing to provide better contents. In addition to the dense composition of the story, the quality of the sound and screen has now become an important factor in the selection of content. That’s why creators around the world tend to produce video content in 4K. This is because 4K resolution videos are more competitive among numerous videos, which can increase demand.

As the video market becomes active, it is said that the demand for equipment and software needed to produce content is increasing. This is because most content creators are trying to provide better quality videos by building better production systems. But for 4K images to be produced, it costs more than what’s normally used. It can be made with expensive products such as 4K and 8K camera, HEVC real encoder, and equipment that enables 3D sound.

If it is difficult to produce 4K video content due to the burden of equipment, upscaling can also be used. The quality of the HD image improves to UHD quality when the content is filmed conveniently with the existing equipment, and the upscaling is done after editing. In addition, kokoon.cloud, which provides with an online upscaling service, enables 4K upscaling simply by uploading without having to install a separate program, allowing anyone to use it without any burden.

A creator who produced 4K video, but the capacity is a problem?

However, even if expensive equipment is purchased or upscaling is used to create 4K content, another concern arises for creators. The capacity of video content will take up much more capacity than existing image content, and creators whose videos are professionally produced may feel burdened by the production due to the rapidly growing capacity of the video.

Most of the units of storage used today are terabytes (TB). However, terabytes have been lacking recently, the biggest cause of this phenomenon is ‘video.’ In particular, the capacity of 4K video that takes less than 30 minutes is close to 20GB, which can be considered to be almost 1GB per minute, so 60GB has to be given when a one-hour video is produced. In response to this, although the burden is slightly reduced with the advent of SSD and HDD, professional creators with a large number of contents that need to be produced regularly will feel the limit of storage space in a short period of time.

However, the lack of capacity does not mean that 4K resolution can be abandoned. Already, 4K video content has become disseminated to the public, and the level of viewing has increased, so image quality is important in order to gain a competitive edge in content. Especially if you’re a professional creator, you can’t give up on any of the elements that make up the content, the sound and image quality of the content. Therefore, what is needed most now is a solution that can make the capacity lighter as the image quality remains the same.

A magical solution that reduces data capacity by half while maintaining image quality

BLUEDOT has introduced ‘PQ-Optimizer’, a technology that optimizes cognitive image quality that reduces data while maintaining image quality. The self-developed AI is designed in such a way that the image is analyzed and preprocessed, so it can be applied regardless of the codec, and it finds and removes pixels that are unnecessary for the implementation of the quality of the image, which makes the difference in image quality almost not visible, allowing the data to be light. Thanks to the increased efficiency of the encoder compression, it solves the difficulties of lack of data capacity of video providers.

Conversely, if the usage of data becomes the same, it can implement higher picture quality. In addition, because less data is used, high-quality images can be reliably transmitted even if live streaming is done on an unstable network. Therefore, ‘PQ-Optimizer’ is a solution that allows creators whose videos are produced to be useful in various ways.

With the surge in demand for video content, the quality of video content has improved at a fast pace and is still ongoing. And there are many ways appearing to improve the quality of the video. With improved equipment, high-quality video content can be produced, but the use of the solution introduced in today’s posting can also be seen as an efficient production method to improve the quality of the video.

Same video quality, but the reduction incapacity

Video content is growing so fast that videos occupy more than 80% of the internet traffic. The mass is actively producing and watching video content. However, the growth of the video content market has some side effects on data. It has become difficult for both the creators that produce videos and video platforms, to handle the enormous capacity of video content.

Then what will be the solution to solve this problem? That is by reducing video data. But reducing video data leads to another problem which is the loss of video quality. Therefore, we need a technology that maintains video quality but reduces capacity.

The reason for the sudden loss of YouTube video quality.

When using YouTube recently, you can notice a big difference. In the past, when you played the video, the video was played in HD quality, but now they are played in lower quality, making us change it back up to HD quality. YouTube supports up to 4K videos, but why does it play it in low-quality videos in the beginning.

The problem is because of the ‘Data issue’. The biggest video platform YouTube tried to reduce the usage, of the sudden increase of the data of video contents by, playing low-quality videos rather than high-quality videos in default. This is an example that the data issue is a serious problem affecting our daily lives.

In addition, the use of smart TVs is also demanding more use of high-quality videos. People using smart TVs enjoy contents, such as YouTube and Netflix, which need high-quality videos. Low-quality videos are more disturbing on a larger screen than on mobile, making the importance of video quality bigger. This makes it impossible for us to give up either the capacity or quality of videos.

‘PQ-optimizer’ is a cognitive image quality optimization technology that save the data rate while maintaining the quality of the video

‘PQ-optimizer’ is a cognitive image quality optimization technology that save the data rate while maintaining the quality of the video. Using self-developed AI reduces data by deleting unnecessary pixels, making it possible to reduce data without the loss of quality.

optimized by PQ-Optimizer

For example, when the computer we use slows down, the first thing that comes to mind is ‘data’. By erasing data, we can make our computers work faster. So we naturally check the usage of data and erase unused documents to maintain data capacity. ‘PQ-optimizer’ also follows this principle allowing users to enjoy the video with lower capacity, by erasing unnecessary pixels in the video.

One thing to notice is that the name of this technology is “cognitive image quality”. In other words, the image quality isn’t the same. But it looks the same in the human eye. Based on the VMAF score released by NETFLIX, when checking the difference from the original video the video that was applied with PQ-optimizer had scored similar. It even had a higher image quality score when using the same amount of data.

The difference ‘PQ-optimizer’ can bring in daily life.

You can see that by using ‘PQ-optimizer’ we can improve coding efficiency to reduce the capacity of videos but maintain quality, allowing us to produce more video content. Thanks to this technology we can produce and enjoy video content freely. Since it uses less data, it can also transmit high-quality videos in unstable network conditions which can be useful in live streaming.

In addition, the PQ-optimizer is a pre-processing technology that can be applied before the encoding system and because it can be applied to all codecs, it does not need the expansion of any new codecs. It can also be encoded better in the same given data and has better encoding efficiency when the quality is the same.

New creators are emerging day by day and they are producing video content actively. The mass also enjoys a lot of video content. As the amount of content is increasing tremendously, we need to prepare for the usage of data. The ‘PQ-optimizer’ introduced today will be very useful in the upcoming data issue.

Upscaling, the best solution for retouching videos.

Facebook, Instagram, and Youtube… SNS have become deeply inside our life. It is because People can record their daily life easily compared to before when we should carry camera to record our memories and stories. As there are various people using SNS, various contents are being upload. However, there is one thing in common that they go through the “retouching” stage.

After taking pictures, retouching stage has become a necessity, not an option. Therefore, various camera applications for retouching photo are being developed and increased popularity steadily. There are a lot of camera applications, but video retouching applications are relatively rare. So I propose that Instead of applications, you can use ‘upscaling’ as a solution that easily retouching videos.

SNS is addicted to video, so I record everything in videos!

SNS tends to prefer videos. For example, when we use Instagram, most of the first appearance popular post when we searching contents is video and they launched ‘reeels’, a platform dedicated to video contents. In particular, ‘Reels’ has become a popular video platform in a short time because they have many similar aspects to video SNS ‘TikTok’. Besides, as YouTube grow rapidly and the number of creators who show their daily life through V-log has increased, more and more people upload video to SNS as a means of recording their memories.

However, V-log without retouching is likely to be ignored in huge SNS’s contents world, because most creators improve the quality by retouching color and skin tone of the video. Therefore, videos without retouching, the ‘raw’ videos seem to relatively low-quality contents. In order to solve this problem, many creators tend to use camera applications that have been retouched from the beginning, and sometimes purchased high-performance cameras.

Both camera application and high-performance camera can enhance video’s quality, but they have disadvantages clearly. First, camera application can retouch skin-tone and highlight beauty of face, but not guaranteed the video’s quality. In addition, there is a risk that decrease quality of the video, shot by camera application, when you watch on a bigger display such as tablet PC or desktop. High-performance camera can make clear video quality on any display, but it is very expensive.

Natural retouching and ease, the best retouching video solution ‘upscaling’.

Upscaling is the best video retouching solution which is able to retouch video naturally while compensate the defects. Upscaling is a technology that enhance video quality, and it can be used freely depending on various purpose of use. For example, even if the resolution of the video is low, upscaling helps to watch clearly on a large display such as TV or if you want retouching whole video’s color to brighter, upscaling could be very useful.

Recently, upscaling based on AI is getting attention. Previously, small video should be blur because of pixels are simply copied and pasted average value of the nearest, but if you use AI to upscale video, deep-learning model expects and generates pixels so it could be retouched naturally and clearly. For example, I upscale my face video to 4K then my skin-tone will be brighter and clearer and accentuate the contour of face, so it makes my strengths stand out.

Another reason why upscaling is the best video retouching solution is ease. Especially, it can use not only software but also online, kokoon.cloud is video upscaling online service to upscale your video up to 4K. When you upload a video, it converts the video to desired size, AI generates pixels to natural upscaling. In addition, the conversion time is very fast to upscale video with the best quality, and you can use everywhere web-capable place.

Upscaling is an optimal video retouching solution that is very efficient in terms of time and price for natural retouching. In strong competition of various video contents, many creators try to make better contents to attract audiences. Wouldn’t it be possible to become winner in this competition if you enhance the quality of videos easily and quickly through upscaling? Try upscaling, easy video retouching solution everyone can use.

How to keep high quality of video on any displays?

With the spread of smart home appliances linked to mobile to the public, more people enjoy video contents such as YouTube and Netflix on larger displays. It is more comfortable and realistic when you play the video on a larger screen than mobile.

However, if you watch mobile-size video on a big screen more than 50 inches arise a big problem. The quality of video gets blurry when you increase the video size. This is a natural result, but people can’t stand this inconvenience. We need to solve this problem and ‘upscaling’, keeping high quality of video on any displays, is the most efficient solution among any technologies.

Upscaling is a technology that global companies such as NVIDIA, AMD, and Microsoft are paying attention to.

Upscaling is a technology that enhances a video to keep quality in detail while increasing video resolution. Today the scope of upscaling is gradually expanding, because the resolution of displays is increasing but the video contents cannot keep up with the pace of screen size. 4K display has already been supplied and now we even watch 8K displays. However, the number of 4K videos are not enough to play and while old videos before HD resolution are popular again, the application of upscaling technology is gradually expanding.

In game industry, upscaling is already being used to improve gaming user experience on PC. NVIDA, global IT company, developed DLSS and get ahead of game upscaling part, and AMD also participate into the upscaling technology field by FSR. Recently, even Microsoft has announced that they are researching upscaling software using AI. As a result, “Upscaling” become the most noticeable keyword in the industry.

Sound like a dream 8K display, but no contents?

There being more reason why upscaling is on the rise, that is a correlation between the development of display technology and the number of video contents. The sales of 8K TV had been steadily increasing since they appeared, but it is slowing down lately. Because people are looking forward to watching on 8K TV very high resolution video which is four times higher than 4K TV, but there are few contents to satisfy 8K TV’s resolution. None of broadcasting stations provide 8K video yet, and OTT platforms such as YouTube, Netflix, and Apple TV also service up to 4K videos.

In current contents creating environment, it is difficult to produce UHD videos such as 4K or 8K. First, cameras equipment which is capable of shooting 4K video is expensive. Although UHD camera is emerging, but video quality is often not good depending on the shooting environment. In addition, it takes long time to produce, so it is very inefficient in terms of cost and time. For these reasons, it is being researched to produce 4K contents by converting to 4K using upscaling to enhance video resolution after producing content at 2K resolution.

Is upscaling professional? NO! everyone can use it.

Even though the scope of using upscaling is expanding and it is a rising technology, but it is still unfamiliar term to public. Is upscaling a specialized technique that can only be used by specialists? No! Upscaling is a very simple technique that anyone can use.

Today, there are more than 2 billion worldwide people using YouTube, and the number of creators is about 50 million, So, in this era where anyone can create and enjoy video content, and the number of users is increasing, video quality improvement technology that enhances the contents is necessary for everyone. For this reason, upscaling technology providers are providing services through software and online so that anyone can experience upscaling easily and simply.

Kokoon.cloud is easy and fast online video upscaling through cloud and we serve online upscaling for free. Just upload your video and start converting, you can make high resolution video without losing quality. We serve our upscaling technology for free so that anyone can experience.


As the video contents market grows, resolution has become a factor in determining the overall quality of content. In addition, the number of contents is increasing, and as display technology is advanced, public users consume contents on more than one equipment. Therefore, upscaling that can achieve high resolution on any display is no longer an option but a necessity.

어떤 화면에서도 선명함을 유지해주는 기술, ‘업스케일링’이란?

모바일과 가전을 연동한 스마트 가전이 대중들에게 보급되면서, 유튜브, 넷플릭스 등 모바일에서 즐기던 동영상 콘텐츠를 더 큰 디스플레이로 즐기는 사람들이 증가했습니다. 커다란 화면에서 영상을 재생하면 모바일보다 편안하고, 실감나게 감상할 수 있기 때문입니다.

하지만 모바일에서 제공되는 영상을 50인치가 넘는 커다란 화면에서 감상하려면 문제가 발생합니다. 영상의 크기를 늘리면 화질이 흐릿해질 수밖에 없는데, 대중은 이런 불편함을 감수하기 보다는 해결해줄 수 있는 솔루션을 필요로 하고 있죠. 그래서 등장한 기술이 어떤 화면에서도 선명함을 유지해주는 ‘업스케일링’ 입니다.

엔비디아, AMD부터 마이크로소프트까지.. 글로벌 기업이 주목하는 ‘업스케일링’

Upscaled by kokoon.cloud

업스케일링은 영상이 커져도 선명한 화질을 유지할 수 있도록 화질을 개선해주는 기술입니다. 4K 디스플레이는 이미 상용화되었고 이제는 8K 디스플레이까지 보급되고 있는 상황이지만 이에 맞는 영상이 턱없이 부족하고, 또한 과거 HD가 등장하기 이전의 영상이 다시 빛을 보면서 업스케일링 기술의 활용 범위는 점차 넓어지고 있습니다.

실제로 업스케일링은 PC에서의 게이밍 성능 향상을 도모하기 위해 이미 활용되고 있는데요, 글로벌 IT기업 엔비디아는 DLSS를 개발해 게임 업스케일링 기술에서 가장 앞서가고 있고, AMD 역시 FSR을 공개하면서 시장에 진입했죠. 최근에는 마이크로소프트까지 AI기술을 이용한 업스케일링 소프트웨어 개발을 추진하고 있다고 밝히면서 ‘업스케일링’ 기술은 업계에서 가장 관심받는 키워드로 떠오르고 있습니다.

꿈의 화질 8K 디스플레이 시장 개막, 하지만 콘텐츠가 없다?

업스케일링이 떠오르는 이유로, 디스플레이 기술의 발전과 콘텐츠 수량의 상관관계를 이야기할 수 있습니다. 8K TV는 2017년 등장 이후 꾸준히 증가하고 있던 판매량이 주춤하고 있는데요, 이미 상용화된 4K TV보다 4배 높은 화질을 제공하며 ‘꿈의 화질’이라고 불리던 TV는 이를 만족시켜줄 수 있는 콘텐츠의 수량이 부족하기 때문입니다. 지상파 방송국 중 8K 영상을 제공하는 곳은 아직 없으며, 유튜브를 비롯해 넷플릭스, 애플 TV등 OTT 플랫폼 역시 최고 4K까지 화질을 구현하고 있습니다.

현재 콘텐츠 제작 환경에서는 8K, 4K와 같은 초고화질 영상을 제작하기 어려움이 많습니다. 4K 영상을 촬영할 수 있는 장비가 부족하고, 초고화질 카메라가 등장하고 있지만 비용이 높고 촬영 환경에 따라 영상의 화질이 잘 나오지 않는 경우도 많습니다. 또한 제작 시간도 오래 걸리기 때문에 비용과 시간적인 면에서 효율이 매우 떨어집니다. 때문에 현재 대부분의 4K 콘텐츠는 기존의 촬영 장비로 콘텐츠를 제작한 후 화질을 개선시키는 업스케일링 기술을 활용하고 있습니다.

업스케일링은 전문적이다? NO! 누구나 사용할 수 있는 아주 쉬운 기술

업스케일링의 활용이 다양해지고, 떠오르고 있는 기술이기는 하지만 아직 대중들에게 생소한 개념으로 다가옵니다. 때문에 업스케일링은 콘텐츠 전문 기업만 사용할 수 있는 전문 기술이라고 오해를 불러일으키기도 하고 용어 자체가 어려워서 이용을 망설이기도 하는데요, 하지만 업스케일링은 누구나 사용할 수 있는 아주 간편한 기술입니다.

전 세계 유튜브를 이용하는 사람들은 20억 명 이상이며, 크리에이터는 약 5천만 명이 넘어가고 있습니다. 이처럼 누구나 동영상 콘텐츠를 만들고 감상하며 이용자들이 많아지고 있는 시대에 콘텐츠의 퀄리티를 높여주는 화질 개선 기술은 누구에게나 필요합니다. 때문에 업스케일링 기술 공급자들은 ‘누구나 쉽고 간편한’ 업스케일링을 경험할 수 있도록 소프트웨어, 온라인 등을 활용해 서비스하고 있습니다.

그 중에서도 온라인 비디오 업스케일링 클라우드 코쿤클라우드는 웹 어플리케이션 형태로 온라인 업스케일링 서비스를 제공하고 있습니다. 보유중인 영상을 간편한 업로드만 거치면 고퀄리티로 향상된 업스케일링 결과물을 만나볼 수 있는데요, 현재 무료로 사용할 수 있으며 특히 빠른 속도를 자랑하기 때문에 부담 없이 업스케일링을 경험할 수 있습니다.

동영상 시장이 거대해지면서 영상의 화질은 콘텐츠의 전체적인 퀄리티를 판단하는 하나의 요소로 자리잡게 되었습니다. 게다가 콘텐츠가 다양해지고 디스플레이는 더욱 발전하면서 대중은 더이상 하나의 디스플레이에서 영상을 소비하지 않게 되었죠. 때문에 어느 디스플레이에서도 선명한 화질을 구현할 수 있는 업스케일링 기술은 더 이상 선택이 아닌 필수가 되었습니다.
