From ‘Video Restoration’ to ‘Face Application,’ how far have you used upscaling?

As the number of people enjoying video content increases, it is ‘technology’ that follows on its own as the market grows. As competition for content intensifies, creators often develop strategies to appeal to the public with higher image quality as well as solid story to provide higher-quality content. Therefore, there will be a demand for technology that improves image quality, and new technology will emerge.

Typically, there is ‘upscaling’. Pixels are created to enhance the resolution of images so that they can be useful when you want to watch them on a variety of displays, or when you want to improve the quality of images. Moreover, once the upscaling technology is applied, it can be used more widely. Among the technologies of various applications, ‘Remastering’ and ‘Face enhancement’ will be introduced today.

‘Remastering,’ which adds modern visual beauty to those days and the mood.

Recently in the media industry, there is a growing craze for ‘remastering.’ At the end of last year, the “Remastering Project” was announced at SM Entertainment, saying that the video of a past-affiliated singer’s music videos and performances would be upscaled 4K and released, and the tour of the last concert of Leslie Cheung, a global star from Hong Kong, was restored to 4K video and released. And the public is showing enthusiastic support for the media’s actions, where past images have been restored to good quality and released.

Remastering is a technology that adds color, removes noise, and focuses on sharpening to restore the image clearly. And when it is gone through the upscaling phase, it is reborn as a complete modern image. Although upscaling is not a major technology, thanks to the addition of pixels, quality images can be produced to satisfy consumers.


In addition, as Cyworld, the SNS of memories, comes back, the contents of the past, including images, are being re-examined. So that each person can be active through SNS, the contents of that time and then are shared and enjoyed with people. When ‘remastering,’ a modern technology, is applied, then its mood is maintained and can be upgraded to video content with modern visual beauty added to it.

‘Face Enhancement’ applied to the video of ‘Face Application’ which was applied only to the photo

‘Face Enhancement’ is literally a technique for improving images focused on facial expressions. In addition to the skin tone, the outline and shadow will be added to make the face more vivid, so it will play a role similar to the ‘Face Apps’ used in the photos. Previously, the function was applied only when Face Apps were turned on and filmed, but with the advent of Face Enhancement, pre-shooting and post-production are now possible. Thanks to this, it is possible to improve the blurriness and low definition that have been the disadvantages of camera apps in mobile.

In fact, upscaling alone can improve basic tone correction and clarity. However, if it is an image that the person wants to improve depending on the type of image, if Face Enhancement is applied, you can receive the result that is improved in the desired direction that standing out the person, and if upscaling is used other tools together, it will improve not only the person but also the overall image quality.

In particular, this is expected to be useful for creators who frequently expose their faces such as V-log and beauty YouTube creators. This is taken with an existing camera, so the naturalness remains the same, and when Face Enhancement is applied after shooting, your face in the screen improves. In addition, the overall picture quality becomes clearer, which can lead to the same effect as the purchase of expensive, high-performance camera equipment.

‘,’ a variety of video upscaling services that capture the taste of creators

Upscaling Video Online “”

“” is an online site where AI upscaling enhance the video image’s quality. In April, the mentioned in this post ‘Remastering’ and ‘Face Enhancement’ functions will be added as well. The upscaling technology currently being offered is also divided into “DeepField-SR1,” which focuses on improving natural image quality and “DeepField-SR2,” which focuses on the removal of noise and emphasis on texture, which can be adapted to the concept of the image.


Moreover, it is also the charm of that your own upscaling style is created as another function is used. For example, the upscaling technology “DeepField-SR2” can be applied after the aforementioned “Face Enhancement” technology is first applied, or after the “Remastering” technology is applied, video content that revives the character of memories can be created.

Because each technology of is excellent, it is possible to receive a satisfactory result even if it is used alone, and the technology can be properly mixed and used according to the direction of the desired improvement. What would it be like when’s upscaling service is applied when your own unique content is created in a lot of content?

Golden Age of virtual human, is it a momentary curiosity or will it be an co-existence?

‘Rosy’, a virtual human changed the flow of the industry by giving tremendous ripple effect to advertisement industry. A ‘virtual human’ created by ‘real people’ not only overtakes advertisement industry such as finance, cosmetics and fashion but also shows performance like top stars ahead of debut as a singer. In addition, various virtual humans appeared in row after the appearance of Rosy and we are getting familiar with living together.

When a virtual human appeared at first, there were public opinions that the current virtual human will also be ended with a short curiosity while referring to ‘Adam’, a cyber-singer who failed in the past. However, if you look at what the current virtual human does, she is attracting more attention as she is active in various fields including advertisement industry, entertainment, and influencers. Then, does it mean that virtual humans become an existence who will continue to be with us in the future?

Virtual human, who is ‘celebrity’ contract with entertainment companies.

Recently, we often hear a news of signing contract between big entertainment company and virtual human. YG Entertainment announced that it has signed an exclusive contract with ‘Han Yuah’, a virtual human of Smile Gate, and ‘Rina’, a virtual human of Netmarble company, had signed an exclusive contract with Sublime, an entertainment company which actor ‘Song Gangho’ and ‘Rain’ belong. Besides, various entertainment companies are announcing their plans for virtual human such as developing their own virtual humans.

As such, virtual humans are extending their field of activity to entertainment business starting as influencers and showing various performances such as singing, dancing, and acting. Since they were characterized by appearance most people prefer, they quickly inform their existence through SNS to get popularity from the public and were able to begin their activities in entertainment industry.

When did virtual humans become popular?

Adam, a cyber singer (Source: Adam Soft)

The beginning of a virtual human in Korea is ‘Adam’, a cyber singer. He made his debut in 1998 and was popular for a while. But his popularity wasn’t continued due to the limitation of 3D graphics at that time, and Adam remained as a failed case. The current virtual humans have overcome the precedent of failure and appeared again has emerged in different situation as before, so many people think it will succeed rather than fail.

The popularity of virtual humans underlies the popularity of Metaverse. Metaverse which combines ‘meta’ meaning virtual and ‘verse’ meaning universe can project our own view of the world into the virtual reality, so it is evaluated as the most promising business. Thanks to contactless culture has become popular due to the pandemic, the public get familiar with virtual world and media also reduced the sense of rejection against virtual humans. In addition, virtual humans are showing activities in various media such as YouTube, Instagram, etc. this made the public accept them naturally.

Evolving AI Human market, possibility of its development is almost limitless!

Another reason the virtual human could grow is graphics. As VR has expanded, the level of graphic has significantly improved than before, so we could realize virtual humans with natural figures just like a real person by adding AI to portraits or videos. As a result, very natural visual that is beyond so called ‘uncanny valley (When human see non-human beings, they feel rather uncomfortable if the level of resemblance is too high)’ was able to create.

Concert of Leslie Cheung that is restored by AI technology (Source: Hong Kong South China Morning Post)

Recently, virtual human based on AI technology can revive the figure in the past. As YouTube became very popular, videos in the past are also actively uploaded. Among them, videos of memory who had already passed away sometimes appeared. However, there were taken too long ago, the quality was not good. However, it was announced that concert tour video of Leslie Cheung in 2000s has restored with 4K quality video.

The concert tour video of Leslie Cheung which is restored by one IT company in China record recording over 10 million views in short time. It said that the background of being able to restore the video was AI. Since AI generated pixel, the figure of Leslie Cheung who was under dark concert hall could be a clear video because AI restored more detailed in the video.

‘kokoon cloud’, a website of improving video quality, is providing a service to improve the quality of videos by using self-developed AI. It allows to enhance video quality by two options such as ‘DeepField-SR1’ that generates the pixel by focusing on subject in the videos and ‘DeepField-SR2’ that erases noise and emphasizes texture. In addition, preparing services of ‘Face-Enhancement’ that is optimized for correcting figure videos and ‘Remastering’ that can restore old videos. Therefore, it is expected to be very helpful tools to create figure-related video contents.

‘Virtual Business’ including virtual humans are deeply related with AI. It creates virtual human by graphics and AI, or it gives an opportunity to meet celebrities in our memories who already passed away. In addition, it is not an exaggeration to say that AI involves in all parts of virtual world such as creating characters by compounding AI and graphics, so I am expected to be emerged another virtual world and the role of AI.

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, 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.

Online video upscaling ‘’ renovated open.

‘Preview’ is new tool in workspace to see upscaled result before download. Click the preview in option window and compare the original video and upscaled result based on the options you set. You can drag the middle bar to move freely to check whether the areas that need to be emphasized or there are any problems.

If you want to compare before and after more precisely, then adjust screen magnification from 100% to 400%, or scale to fit. Especially, have two versions of upscaling that apply different AI models, so user can get a better upscaling result by comparing which version goes best with the video.

3. Two versions of upscaling to satisfy user’s style. added new features for new website, the most notable part is ‘Deepfield-SR2’, another version of upscaling.’s upscaling is based on BLUEDOT’s ‘Deepfield-SR’, recently BLUEDOT developed new AI model to meet user’s needs. It applied to ‘Deepfield-SR2’, and both can use in

‘Deepfield-SR1’is same as before, AI generates pixels focusing on objects, so it enhances video naturally and quickly. The other version of upscaling, ‘Deepfield-SR2’, is focused on erase noise. it deletes only noise and emphasize textures, so it upscale more moderate than ‘Deepfield-SR1’. Two versions of upscaling have different characters, you can choose on your style.

4. The first impression of, main page. how to use?

The main page of introduce what kind of work we do to guests. ‘How to use?’ is a tutorial video showing how to use workspace, and users send any opinions like improvements or concerns using ‘Talk to Sales’. Above this, it introduces’s communities like YouTube, Facebook, and Blog. is planning to make various attempts from this renovation. We provide other useful video solutions except online video upscaling and better services by communicating with users through newsletters and SNS communities. All of this is thanks to steady increase’s users and the continued positive evaluations of our upscaling quality.

Why YouTube supports 4K videos?

More than 50 billion worldwide creators upload about 24,000 hours of contents in an hour, and more than 2 trillion users watch these huge number of contents. The value is recorded by YouTube, the word’s largest video platform.

Sometimes YouTube to be a standard for video contents. What is the trendiest contents? Who is the rising creator today? When I curious those information, I always search in YouTube. As such, YouTube is leading video contents market with steady changing and innovating. And supporting 4K videos is one of the various and innovative changes in YouTube. 4K has more pixels than HD about 4 times, so it express video definition in high quality. Then I curious a question, why the video trend leader YouTube supports 4K videos?

4K, the symbol of high-definition videos.

4K means there are about 4,000 pixels in the video horizontal. It also used to refering Ultra-high definition resolution and called 4K UHD(Ultra HD). 4K video’s size is 3840×2160, which is 3 times bigger than HD, and the quality is outstanding because it has more pixels than Full HD 4 times. When 4K appeared, 4096×2160 and 3840×2160 were used together but CEA(Consumer Electronics Association) set the size 3840×2160 in 2012, which is the current standard.

In 2012, South Korea transmitted 4K video for test broadcasting and start the era of 4K from while live broadcast 4K UHD some matches in Brazil world-cup 2014. Since then, 4K display market has grown rapidly because 4K contents has increased, now we watch 4K videos in daily life like desktop, laptop etc.

YouTube attempted to build a platform to watch 4K videos in 2015 for preparation the popularization of 4K videos. First, they test platform operation by playing 6 4K videos, and then provide 4K resolution function. YouTube provides SD, HD, 4K resolutions, and the highest resolution user can watch is 4K. In conclusion, supporting 4K on YouTube, the largest video contents platform, means that 4K has become the standard of high-quality video in the world.

Satisfied the public addicted to watching!

Not only YouTube, OTT platforms such as Netflix also play 4K contents because the vido trend have been changed. From 4K display is commercialized quickly, people watch videos on various displays like desktop, TV and they want to keep high quality on any displays.

Recently, Google Chromecast is very popular in South Korea. Even before release, many people order it online from overseas. In addition, the new version of TVs support video platforms such as YouTube and Netflix, Google Chromecast is gaining popularity more and more.

This means that people who watch videos on mobile to TV display have increased. Video content area has become huge thanks to people watch videos increased rapidly and videos become diverse for people who want to enjoy spare time. Therefore, people are inconvenienced when they watch video content on a small mobile screen for a long time, so they prefer to bigger display to watch video more comfortably.

Is the successful 4K video at stake?

However, I am worried about the future of 4K video because the number of contents provided in 4K is insufficient to satisfied public who are looking forward to high-quality video content. Besides, some defects that it is expensive to produce 4K contents and if the popular content you previously owned is not 4K, we cannot meet the demand to watch it in high quality.

Upscaling is the most effective solution to solve the problem. Upscaling can convert the video finished shot to 4K, it means that you can enhance HD video 3 times to 4K thanks to upscaling. It is much cheaper than shot 4K video through high-performance camera and even convert the video you already have. Video creators can use upscaling very usefully to make high quality contents. is fast and easy video upscaling online service, anyone can upscale video through website for free.

Video resolution will be important factor to evaluate and YouTube which is leading the trend of video contents are realized it, so they play 4K video to public. I think the decision have affected users in YouTube to increase.

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.

upscaled by

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. 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.

AI technology, How far will it develop?

Today, we ask machines questions that may be asked to people such as ‘Tell me the title and singer of the song playing right now’, ‘What’s the most popular movie in cinema these days?’, ‘How is the weather today?’. However, Now is the era where no one finds it weird, this is thanks to ‘AI (Artificial Intelligence)’ that permeated our lives as a whole.

This technology called ‘Artificial Intelligence’ or ‘AI’ is a computer technology that artificially implements human learning ability, inferencing ability, and perception ability. Because AI can apply what humans have to do to machines, it has many advantages, such as a wide range of applications, reducing labor costs, and replacing some of people’s roles in the current situation where the population is increasingly scarce.

The life with ‘AI’ that now we are accustomed


The opportunity to imprint unfamiliar Artificial Intelligence on the public was the Go match between AlphaGo and Lee Se-dol held in 2016. As the match between AlphaGo, an Artificial Intelligence Go program developed by Google’s DeepMind, and Lee Se-dol, a human who boasts the highest Go skills, drew public attention, the public could see what role the Artificial Intelligence plays. Since then, various services with Artificial Intelligence have been created, and the life with AI has begun.

Representatively, there is an Artificial Intelligence speaker. The artificial intelligence built into the speaker acts as a secretary, enabling conversation like humans, and providing information. It was a rather unfamiliar product, but it boasts quite a lot of popularity and has become a common item in our daily life. AI is preferred by office workers who live alone because of its various function such as listening music, weather prediction and alarm, and it plays many roles such as being a conversation partner for the elder who lives alone in a situation where face-to-face contact has become difficult due to COVID-19.

Autonomous driving is also a representative industry in the field of applying Artificial Intelligence. Autonomous driving reduces the energy consumption of drivers by helping cars recognize traffic conditions itself and drive safely, which shows how much AI contributes to human life and proves the high value of technology. Actually, Hyundai Motor Company is making generous investments and showing continued interest by selecting AI technologies such as autonomous driving and Urban Air Transportation (UAM) as key technologies that will be responsible for the future.

The more upgraded world of Graphics due to AI

Also, another field that has drew attention due to the application of AI is ‘Graphic’. Using Artificial Intelligence technology, viewers are amazed by real graphics because it can realize more realistic graphics by reducing the difference between the screen and reality. Additionally, A new area has been also created as the level of graphics have been upgraded surpassingly due to application of AI.

Virtual Influencer ‘ROZY’ (Shinhan Bank)

‘Virtual influencer’, which was created as a virtual human being by applying AI technology to the face of a real person, is now the best model. Virtual influencer does not cost labor, can be controlled, and has no time and space limit, so it can be used in many places at the same time. As a result, it is very efficient in terms of time and cost, so various brands are showing interest in marketing content in collaboration with Virtual influencer. The popularity of Virtual influencer, which appears in advertisements of almost all brands, can be attributed to the fact that Deepfake technology using AI has reduced the difference between reality and virtuality.

Upscaling, a technology that improves video quality, also brought about further upgraded results thanks to AI. The existing upscaling technology, which enlarges the video by copying the average value of pixels, often can increase the resolution of the video, but the quality becomes blurred. However, When Artificial Intelligence technology is applied, the trained AI inferences and generates pixels that best match the video at high resolution, so the video not only enlarges but also maintains clear image and high quality.

KOKOON Cloud’s upscaling technology also applied AI. Its proprietary Artificial Intelligence trained from numerous video data generates the most suitable pixel, enabling the best quality improvement that is natural overall and does not lose details even if looking closely. Even if you enlarge the 640x360p SD video to 3840x2160p 4K, you can see videos with improved quality without breaking off.

On the other hand, there are voices of concern about now that AI technology is deeply entering our life. It hasn’t been long since AI was involved in our life, and various trials and errors may occur because we are currently in the stage of establishing a direction to life with AI. But the clear thing is that thanks to Artificial Intelligence, the quality of our life will be better and we live a more wealthy and convenient life.

동영상을 보정해주는 최적의 솔루션, 업스케일링

페이스북, 인스타그램 등 SNS는 생활 속에 깊숙이 자리잡았습니다. 스마트폰의 보급화로 따로 카메라를 들고 다니지 않아도 개인의 일상을 쉽게 기록할 수 있어 SNS를 통해 자신의 추억을 기록하고 이야기를 담는 것인데요. SNS를 이용하는 사람들도 많고, 그들이 업로드하는 콘텐츠는 다양하지만 ‘보정’의 단계를 거친다는 공통점이 있습니다.

사진을 촬영하고 보정하는 것은 선택이 아닌 필수가 되어 다양한 사진 보정 어플리케이션들이 출시되고 있으며, 아예 보정된 상태로 촬영을 할 수 있는 카메라 어플리케이션들도 꾸준히 인기를 지속하고 있죠. 하지만 상대적으로 동영상을 보정할 수 있는 툴은 잘 떠오르지 않는데요, 대신에 간편하게 동영상을 보정해주는 솔루션으로 ‘업스케일링’을 이용할 수 있습니다.

동영상에 홀린 SNS, 이제는 영상으로 기록한다!

SNS는 동영상을 선호하는 추세입니다. 인스타그램을 예로 들었을 때, 검색 후 나오는 첫 번째 인기 게시물은 대부분 동영상인 경우가 많고 ‘릴스’를 개시하면서 동영상 콘텐츠 전용 플랫폼을 만들었죠. 특히 릴스는 동영상 SNS 틱톡과 유사한 면이 많아 빠른 시간에 인기 있는 동영상 플랫폼으로 자리잡았습니다. 게다가 최근 유튜브가 급부상해 브이로그로 자신의 일상을 보여주는 크리에이터들이 증가하면서 동영상을 기록의 수단으로 이용해 SNS에 업로드 하는 사람들이 많아졌습니다.

하지만 SNS 세상 속에서 보정 없는 브이로그 콘텐츠는 외면 받기 십상인데요, 대부분의 사람들이 이미지의 전체적인 색감, 피부 톤 등을 보정하면서 퀄리티를 높이기 때문에 보정 없는 ‘날 것’의 동영상은 상대적으로 콘텐츠의 질이 하향되어 보이기 때문입니다. 이러한 문제를 해결하기 위해 많은 콘텐츠 크리에이터들은 촬영부터 보정이 되어 있는 카메라 어플리케이션을 사용하는 추세이며, 고성능의 카메라를 구입하기도 합니다.

보정 카메라 어플리케이션과 고성능 카메라 모두 영상의 퀄리티를 높여줄 수 있지만, 분명한 단점을 가지고 있습니다. 우선 카메라 어플리케이션의 경우 피부 톤을 고르게 맞춰주고, 얼굴의 장점을 살려줄 수 있지만 영상의 화질이 보장되지 않습니다. 게다가 어플리케이션으로 촬영하게 되면 화질이 떨어지는 경우가 많아 태블릿 PC나 데스크톱과 같은 큰 화면에서 보면 오히려 퀄리티가 낮아 보일 위험이 있죠. 그리고 고성능 카메라는 어떤 디스플레이에서도 또렷한 화질을 자랑하지만 가격이 매우 높다는 단점을 가지고 있습니다.

자연스러운 보정에 간편함까지 갖춘 최적의 동영상 보정 솔루션 ‘업스케일링’

그리고 업스케일링은 앞서 언급한 두 가지 단점을 보완하면서 자연스러운 보정이 가능하다는 장점까지 갖춘 최적의 동영상 보정 솔루션이라고 할 수 있습니다. 업스케일링은 화질을 개선해주는 기술인데, 사용하고자 하는 목적에 따라 자유자재로 활용할 수 있죠. 예를 들어 촬영한 영상의 해상도가 작아도 큰 TV 디스플레이에서 또렷하게 영상을 감상할 수 있도록 도와주기도 하며, 영상의 전체적인 색감을 환하게 보정하고 싶을 때도 업스케일링은 매우 유용합니다.

특히 최근에는 AI를 이용한 업스케일링이 주목받고 있는데요, 작은 영상이 흐릿해지는 이유는 가장 가까이에 있는 화소들의 평균값을 단순히 복사해서 붙여넣기 때문에 영상 내 경계선이 오히려 무너지게 되기 때문입니다. 하지만 AI를 활용하게 될 경우 딥러닝 모델이 화소를 예측해서 생성하기 때문에 보다 자연스러우면서 또렷한 보정이 가능합니다. 예를 들어 얼굴이 나온 영상을 업스케일링 한다면 피부는 깨끗하게 만져주면서 음영은 살리고, 전체적인 피부 톤을 화사하게 만들어줘 장점을 돋보이게 합니다.

그리고 업스케일링이 최적의 동영상 보정 솔루션으로 떠오르는 또 다른 이유는 간편하다는 점입니다. 특히 소프트웨어를 설치하지 않아도 온라인으로도 할 수 있다는 큰 이점이 있는데요, 온라인 비디오 업스케일링 사이트 코쿤클라우드는 촬영된 영상을 업로드 하면 원하는 사이즈에 맞춰 영상을 변환해주고, AI가 화소를 생성해줘 자연스러운 보정이 가능합니다. 게다가 변환 시간이 매우 빠른 편이어서 인터넷만 있다면 어디서든 빠르게 퀄리티 좋은 결과물을 받아볼 수 있죠.

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’

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.
