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.

CYWORLD

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.

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

Moreover, it is also the charm of kokoon.cloud 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 kokoon.cloud 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 kokoon.cloud’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?

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.

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, kokoon.cloud 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, 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.

On 24th Mar, online video upscaling based on cloud service, ‘kokoon.cloud’ renovated open. Kokoon.cloud is getting famous at home and abroad because they serve fast and easy online video upscaling, and it can upscale up to 4K and great quality. We decide to renovate website for better service to more users.

Through this renovation, we focused on maintaining ease of use as before and adding new tools so that users upscale with higher quality. First, separate workspace and add preview tool, especially we introduce new upscaling version that added new AI models. Users can get upscaling results tailored to their favor.

1. Make workspace for focusing on upscaling

kokoon.cloud workspace

Kokoon.cloud separate main page and workspace to users can upscale their video more easily. In addition, users can set details like resolution, video format, quality, etc. to taste, it calls ‘option’. You can make various options on a video to different results.

Even though workspace is separated and provides more sophisticated upscaling through setting options, kokoon.cloud maintains the ease of use. Upload your video on workspace and set option on your way, then click ‘PROGRESS CONVERTING’ button to upscale. If you click the original video, only display the video’s result, so users can see which one is the upscaling video without being confused.

2. ‘Preview’, you can compare B/A before download.

kokoon.cloud preview

‘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, kokoon.cloud 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.

Kokoon.cloud added new features for new website, the most notable part is ‘Deepfield-SR2’, another version of upscaling. Kokoon.cloud’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 kokoon.cloud.

‘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 kokoon.cloud, main page.

kokoon.cloud how to use?

The main page of kokoon.cloud 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 kokoon.cloud’s communities like YouTube, Facebook, and Blog.

kokoon.cloud 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 kokoon.cloud users through newsletters and SNS communities. All of this is thanks to steady increase kokoon.cloud’s users and the continued positive evaluations of our upscaling quality.

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.

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

Google

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.
