The concert of "Hot·Love" poured into Leslie Cheung's enthusiasm for the Chinese music scene, and has become a classic work in the hearts of many viewers. CCTV once gave this concert a high evaluation that "from performance form, artistic concept, costume props, and audience responses, all represent the highest level of Chinese concerts, and no one has surpassed them to this day."
He performed his tortuous and legendary life in a concert, and also brought an avant-garde, gorgeous and elegant audio-visual feast to all the audiences.
is a classic work recreating Leslie Cheung. On April 1 this year, the "Leslie Cheung 2000 "Hot Love" Concert Ultra-clear Repair Edition" was jointly presented by Tencent Cloud Multimedia Laboratory's top algorithm team, Tencent Music Entertainment Group and Global Music's brand Polygin, and jointly presented by Tencent Cloud, WeChat Video Account, Tencent Video and other teams for the first time.
This is also the first time that the masterpiece of the "Hot Love" concert has been repaired in ultra-high definition, and has been treasured on Polygon Records before. Thanks to the support of digital repair technology, this "Symbol of the Times" that has been blocked for more than 21 years has been unlocked for the first time. Through live broadcasts on platforms such as WeChat Video, Tencent Video, and Tencent Music Entertainment Group, it has relived the peerless style on Leslie Cheung's stage.
Dust-sealed master belt was repaired for the first time
Every April 1, many fans of Rong will express their remembrance through various forms such as sharing Leslie Cheung's works during his lifetime and pay tribute to the classics.
Now spring has passed and autumn has been around for 21 years. Due to the storage media of shooting equipment and video materials at that time, Polygon now has mastering belts for 21 years and the "Hot Love" concert version circulating on the Internet, the video quality is generally poor.
In view of this, Tencent Music Entertainment Group contacted Universal Music at the beginning of this year, and the two sides decided to start the mastering work of the "Hot Love" concert through multimedia laboratory restoration technology.
took several months of preparation. Leslie Cheung's "Hot Love" concert masterpiece was repaired for the first time, and was presented as scheduled at 8 pm on April 1st in the form of a global live broadcast, which resonated with countless fans of the glory.
"Keep the warmest side of the world, keep warm and spend the coldest day..." In the live broadcast room of the concert that night, many fans put Leslie Cheung's classic lyrics on the public screen to express their nostalgia for Leslie Cheung and his classic works.
also left a message saying that the ultra-clear repaired version, Leslie Cheung's face, stage and other details are clearly visible, and she feels like she dreams of 2,000 years.
Leslie Cheung is no longer a simple name, but a cultural imprint of an era. With the rise of Cantonese pop music, Polygon witnessed the golden age of Hong Kong's record industry, and Leslie Cheung is one of the most influential singers under Polygon.
"As a king-level singer, Leslie Cheung can achieve self-breakthrough in the concert and face himself sincerely, which is one of the reasons why he cannot be replaced in the Chinese music scene." Music critic Ding Huifeng said, "A lot of the content displayed in the concert of "Hot Love" is very advanced, and even in 2022, if you look back, you will still feel that this concert is very amazing."
music brings warmth, and the video account "Yin Yuehui" ecology is booming. In December last year, Westlife's first online live concert appeared on the video account, attracting more than 27 million people to watch and break the circle strongly. At the beginning of 2022, WeChat Video Account and the Central Committee of the Communist Youth League jointly held a large-scale live broadcast of "Chasing the Light", and the "Chasing the Light" concert also brought strength and warmth to many audiences at the beginning of the new year.
In addition, musicians such as Chen Hongyuhua have also held "online concerts" on the video account platform. In addition, many medium and long-tail music creators continue to release short video works and carry out live broadcasts, and high-quality music content is constantly being presented to the majority of video account users. Against the background of the epidemic, even though I haven't watched a concert for a long time, "You can listen to live and watch concerts by opening the video account" is becoming the daily life of more and more people.
The technical challenge behind the repair of "immersion"
"With the accumulation of technology such as the laboratory's repair engine, the clarity of the concert video can be greatly restored. However, for problems such as fast color and picture switching in the concert video, coupled with the low clarity of the video material, how to repair the old as before and bring the audience the immersive experience integrated into it is a big challenge for the team."
Repairing historical image works and even damaged images is no problem for experienced multimedia laboratories, but when receiving this demand, Xia Zhen, an expert researcher at Tencent Cloud Multimedia Laboratory, and his team were still relatively nervous.
After many research and technical verifications, Xia Zhen and his team have set a hard standard for this repair work, that is, the repaired images can bring a "live" viewing experience to the fans of the Rong Dynasty. The technical code to unlock this "key of time" is the "ultra-clear immersion repair engine" of the multimedia laboratory.
Tencent Cloud Multimedia Laboratory is one of the world's leading multimedia communication and processing R&D teams. It has accumulated complete solutions and leading technical levels in the fields of multimedia data transmission and compression, smart converged media, interactive immersive media, etc. It also has a deep technical accumulation in the field of image repair, and has a number of industry-leading old film repair technologies such as the "ultra-clear immersive repair engine".
The repair engine has many highlights, such as "face repair". It is based on the face repair model developed by Tencent Cloud Multimedia Laboratory. It uses face detection, face repair and fusion modules to migrate image repair to the video process, add inter-frame stability processing to solve the stability of face detection, optimize multi-angle face effects, and solve the complex scene problems encountered by dynamic faces in videos.
In order to create a "face-to-face" effect for people, the laboratory team also made special algorithmic adjustments to the details of Leslie Cheung's concert. A static image of Leslie Cheung in the center of the stage was captured from the repaired video. After zooming in, it seemed that the outline of the refracted image of the stage could be seen through his eyes.
"As a fan of honor, during the restoration process, my brother's smile gradually appeared in front of me, which moved me deeply. I was also very happy to be able to make some contributions to the inheritance of classic images through technology!" After watching the live broadcast of the concert restoration that night, as well as the audience's active interaction and feedback on the public screen, Xia Zhen finally breathed a sigh of relief.
technology has great potential to help inherit classic culture.
In fact, behind the live broadcast of Leslie Cheung's "Hot Love" concert, it is reflected that China has a large number of classic film and television works and cultural images that need to be repaired urgently. At present, digital technology is becoming an important driving force for cultural heritage and promoting the development of the ultra-high-definition video industry.
The "Action Plan for the Development of Ultra HD Video Industry" jointly issued by the Ministry of Industry and Information Technology, the State Administration of Radio and Television, and the China Central Radio and Television Station clearly states that by 2022, the total scale of the ultra-high-definition video industry will exceed 4 trillion yuan, and the production of ultra-high-definition content will exceed 30,000 hours per year. However, in the ultra-high-definition content production, there are pain points such as high cost and low efficiency in ultra-high-definition content production, classic old films and videos to high-definition, which have become the key factors restricting the development of the industry.
At present, Tencent Cloud Multimedia Laboratory has formed a relatively complete matrix of intelligent old film repair technology. In addition to Leslie Cheung's "Hot Love" concert, he also participated in the high-definition restoration of classic films and TV series such as "Kangxi Dynasty" and "The World" and precious historical images.
" Through the Polykin's "Hot Love" concert restoration project, we can see the value of digital technology in supporting classic video works and traditional culture. Our team is also actively cooperating with some cultural institutions to discuss the restoration of more classic film and television works.”
Dr. Liu Shan, an outstanding scientist of Tencent and general manager of Tencent Cloud Multimedia Laboratory, said that Tencent Cloud Multimedia Laboratory will continue to explore the social value of digital technology in the future, promote the implementation and application of multimedia technology in multiple industrial fields, while practicing Tencent’s sustainable social value innovation and helping the inheritance of classic culture.
