More and more "Ye Qing Hui", the technical empowerment of the old film repair and improvement is not just the picture quality

Text | Lin Bomizi

In the Beibei Festival, the market has once again verified that "the classics will never be out of date."

During the North Film Festival this year, many classic films such as "Godfather", "Shell Motor Team", "Harry Potter and Magic Stone IMAX", "City of Sky", and other classic films have been snatched in less than 1 minute of invoicing, and they were snatched and empty, and while they were snatched and empty, and they were snatched and empty, and they were snatched and empty, and they were snatched and empty. In addition to these overseas content, the 4K repair version of the "Big Tissue Tiangong" 4K repair version of the first animated long film after the founding of the People's Republic of China also received the same treatment.

It should be said that classic films have always had a certain market. When they don't know what to watch, people will tend to relive the classic content. In the cinema market that has been impacted by the epidemic in the past two years, classic old films are also the reason why people have mobilized people to enter the cinema. According to the "2020 Cinema Research Report" released by Tao Tickets, the main force of the movie after the 95th after the 95th was re -entered. Classic films such as "Harry Potter and Magic Stone", the post -95s are also the user group with the most ticket -to -view movie viewing.

Most of the classic old films we can see today have experienced the process of repair. As more and more platforms start the process of repairing old films, we have also seen the charm of the technology that is amplified.

Why do we need a classic old film?

When it comes to classic old films, the annual holidays of "Returning Pearls" and "Journey to the West" seem to be unable to escape the topic. For many post -80s and post -90s, these classic film and television dramas can be said to have changed from consumer goods to necessity.

Watching old movies is no longer important for many people, what is important is the emotional precipitation and companion value.

Over time, we always face new things and new living conditions. In this "new", there are beauty and restlessness, and the past, because of the past, will bring us a sense of security. This is why TV series such as "Returning Pearls" can be repeatedly watched for more than ten years, because playing "Returning Pearls" may just make people feel relaxed.

Including online popular words such as "Ye Qing Hui", it also reflects people's preference for classic content. Classic old films and adolescents are related to the state and emotions. Pushing, this feeling also makes people feel different about classic old films.

In addition to the emotions that we project on the content, sometimes, old films are also a carrier of emotional continuity.

Like "Gourd Brothers", "Black Cat Sheriff", "Big Head Son and Little Dad", "Little Tadpoles Finding Mom" ​​and other classic cartoons. They are memories of childhood after 90s, and when they become parents and parents Later, I also hope that the classics I can see when I was a kid can be seen by my own children. This is also the emotional transmission through classic content.

From a more rational perspective, the value of classic content is not only emotional.

The content of the word "classic" is almost all of the quality of quality, which is obviously different from fast food content. Old films like "Godfather" have its charm no matter how long it is, in the display of content to human nature, and the content of "Shell Motor Team" has exerted imagination but left the characteristics of the times.

In the process of watching the classic old films, we are not just immersed in the wonderful stories in the past, but also have new feelings and new thinking because of the spirit and core conveyed. Known as a classic reason.

From this perspective, classic old films are an indispensable part of the market. However, with the advancement of technology, various high -resolution display equipment and transmission bandwidth have enhanced the market's viewing experience. At the same time, the market's requirements for video experience are getting higher and higher. The proportion of abandoning dramas in one minute is as high as 70%. This reality also puts forward new challenges to the humanistic and artistic value of classic old films.

What makes more and more old films rejuvenating?

In the past two years, the term "old film restoration" has been mentioned more and more because the industry realizes the diverse value of the classic content on the market, but the repair of the old film is not as easy as it is.

In the past, the old film restoration was a craft, which requires experienced repairers to include physical cleaning, "glue transfer" collection, digital repair and other links. Many of them take a lot of time and energy. The improvement of the improvement needs to be adjusted frame by frame. Conventional films are 20-45 frames per second. Each old film is 20 minutes-130 minutes. Such a film restoration can be imagined by the time consumption of picture quality. how long.

At the same time, an experienced repair division is scarce resources, and there are a few people who are willing to invest in old films. Some repair divisions stated in the documentary "The Movie", "A film is about 150,000 frames. Several people are repaired together, which can be restored 5000-6000 frames per day. Nothing, this is something I felt bitter at that time, I felt so bitter. "

This makes it a long and high -cost thing in the past. In 2014, the China Film Foundation launched an old film restoration fund. In the past 8 years, the Chinese government allocated 370 million yuan to complete the digital transcoding of nearly 7,000 movies and the repair of 210 movies.

Fortunately, the fixation of the old films is different now.

For example, last October, the volcanic engine and watermelon video held in Beijing to hold the "Restoration of the Old Good" classic video 4K repair conference, saying that the two parties will jointly restore 100 classic animations. As of now, 71 films have been completed. The 4K repair version of "Bagua Tiangong" is one of them. In less than a year, more than 70 animated films are improved, and the efficiency improvement lies in technical support. It is understood that when the volcanic engine faces the repair of the old film, it adopts a set of picture quality to improve the full -link solution from picture quality testing, non -participation scores, picture quality scores, targeted post -processing, and playback recycling. Old film quality determines the degree of repair for an old film, and then uses different technologies to "symptomatic medicine" according to the specific level.

In terms of improvement, the volcanic engine uses super -resolution reconstruction and to fuzzy algorithms, so that the algorithm model learns high -definition video characteristics, so as to complete the conversion of videos from low to high -definition, and generate missing details;

In terms of improvement, the smart frame algorithm is used to analyze the content of the front and rear frames to generate intermediate frames to increase the frame rate to increase the smoothness of the screen;

In terms of color, the algorithm is used to perform automated detection and correction of the color bias of the picture, and to adapt to the color standards of the latest display equipment, the brightness range of the old film is expanded;

To eliminate defects, the volcanic engine combines traditional signal processing and deep learning algorithms to repair different degrees of granular noise, bad points, and scratches of different sizes.

After such a set of processes, the repair of the film seems to have been completed, but the repairs of the old film of the volcanic engine have aroused our attention because it uses technology, but does not "superstitious" technology.

For example, in the process of repairing, the algorithm sometimes misjudges the details of the texture. As a result, the subtitle contour is blurred, so after the volcanic engine confirms that the algorithm cannot solve everything, it has determined the three -step method of "algorithm+artificial+algorithm" to complete the whole process of the old film repair: first use the algorithm to improve the old film, The overall image quality, then use artificially to find the flaws that the algorithm cannot solve for auxiliary labeling, and finally adjust the algorithm for secondary optimization.

This processing step is to keep the artistic effects and artistic style of the old film in the process of improving the picture quality and eliminating defects, and to repair and restore it as much as possible, rather than destroy it. The old animated film can still see the reasons for the charm of the old film.

That is, because there is a platform that rationally use artificial and algorithm technology such as volcanic engines, the efficiency of the repairs of old films greatly improves, so that more and more old films can stand in the market again. Opportunities for young people.

The optimization of the full link of technology empowerment is that the content changes is that the content is more life

The first appearance of many old films was on TV, cinema, and even open -air movies. Nowadays, the development of online video platforms has changed people's viewing habits and viewing scenarios. The classic content has also been moved to the Internet, becoming an important content asset for online video platforms.

Last year, 49 exclusive restoration classic movies on the iQiyi platform received over 12 million views. After Youku launched the "HD Repair Plan" in 2017, the HD classic library also ushered in more than 60 million 90 After watching the movie users, I contributed 42.7%of the viewing time, which is probably why many video platforms today value the repair of the old film.

As a volcanic engine that provides cloud services, in the process of reimbing the old film, not only pays attention to the improvement of the picture and sound, but also take into account the optimization of the video platform online. This is also a cloud service platform based on the Internet. From content fixes to the "full link picture quality optimization plan" of communication optimization.

It is understood that all the repaired old films, especially the classic cartoons broadcast on watermelon videos, are optimized and technical support by volcanic engines in multiple links, including distribution, playback, experience data, quality platform data, etc. That is to combine user data and algorithms to send classic old movies to suitable users.

In other words, the repaired classic content was not "thrown" to the platform, but was carefully placed on a suitable shelf through the optimization of technology. For example, users who are interested in ink style on weekdays may see the classic animation of "Xiao Xun Finding Mom" ​​through the platform's recommendation, and then from surprise to like. This user is satisfied with the video platform is the video platform. We provide more values ​​provided on the old film repair link.

In order to make this value be played larger, the volcanic engine video on demand and intelligent processing products also launched a low -cost picture quality enhancement solution for the lighter magnitude model. Combined with the leisure time processing strategy, the collection of complex algorithms will be collected. The reinforcement technology of image quality has reduced the threshold for usage and assisted more corporate customers in large -scale applications, so that optimizing the image quality is no longer exclusive to the big video platform.

We look at various cultural content in order to get emotional and ideological satisfaction. The fixing of the old films of each platform is to provide more emotional value with the help of classic content while enriching people.Including the empowerment of watermelon video, the volcanic engine not only cooperates with its old film repair, but also opens some of the capabilities of the old films, so that ordinary users can repair old photos on it and regain the beautiful memories of the past.The existence of technology is to improve efficiency and provide more reasonable solutions. Behind more efficient, it is often linked to people's quality of life. The technical empowerment changes not only the appearance of classic old films in people's eyes, but also means us.Life is changing.These technologies provided by volcanic engines also mean that technology can no longer only serve the industry, but also serve every ordinary person, so that we can focus more on the present and future beautiful life. This is also the brought by technology empowerment.The maximum value.
