Artificial intelligence powers film and television drama "Classic Forever"
"I love watching old dramas and movies now, because the classics will never be out of date." Dong Qiang, a "post-90s" guy, is a senior "old drama" and "old movie" lover. Classical film and television dramas such as Detective Di Renjie, "Underground War" and "Old Well" are his normal life. Dong Qiang found that since 2019, some of his favorite classic film and television dramas have become clearer in picture and sound. What he didn't know was that the improvement of the viewing experience of these classic film and television plays is inseparable from artificial intelligence technology.
Data show that the annual production of Chinese-made TV dramas has stabilized at more than 300 units and 10,000 episodes over the years, ranking first in the world. At the same time that TV series are constantly updated, classic movies and TV series with collective memory are still popular with many audiences.
"Classic chewing repeatedly, the more you chew, the more flavor, you can see different connotations every time." Dong Qiang said that there are still many young people like him who like to watch old dramas and movies repeatedly. "It brings Give me a feeling of blood and relaxation. "
The reporter learned that there are two ways to repair classic film and television dramas: one is to repair it manually, and the other is to use computer technology to repair it. In recent years, iQiyi and Youku, Chinese Internet audiovisual platforms, have begun to restore classic old dramas and movies. In 2019, iQiyi launched the "Classic TV Drama Digital Repair Project", which uses independent research and development of ZoomAI intelligent enhancement technology to digitally repair 49 classic TV dramas and 22 movies in 4 batches; on the eve of National Day, Youku repaired it with exclusive technology. 27 patriotic classic movies and TV series.
For ordinary viewers such as Dong Qiang, the repaired TV series gives them a better audiovisual experience; for Internet audiovisual platforms, this means that they need to empower the repair work through technological innovation.
According to Liu Junhui, senior director of iQiyi's intelligent platform department, ZoomAI is an image quality enhancement solution developed by iQiyi. It consists of multiple algorithm modules such as super resolution, color enhancement, sharpening, scratch removal, and white balance. , Repair and enhance the picture quality through artificial intelligence technology.
Liu Junhui said that there are three links in the restoration of classic film and television dramas. One is to digitally convert old dramas with lower resolution to adapt to the restoration. The other is to recolor and enhance the color to solve the problem of dark colors. The third is to restore the drama. Clear picture and denoise sharpening to solve media scratch and noise problems.
"It's easier said than done. We need to correct a little bit of skin color, picture, color temperature, etc. in different situations," said Wang Zhaonan, executive editor of iQiyi. The repair of old dramas is complicated, and artificial intelligence must first learn how to target different images. The repair was performed, so the programmers sought advice from the artificial repair team of the China Film Archive, and compared the artificially repaired TV series "Desire" with the artificial repair version, and then learned how to improve the quality of the episode while ensuring its sense of time and realizing Film and television works "repair the old."
"Every classic film and television drama is a microcosm of longing for a better life, and it is also an expectation of future life." Wang Zhaonan believes that in the future, artificial intelligence will be able to repair 4K, 8K and other high-definition videos, so that those who can spread and scream. Xiang's works achieve "classic perpetuity".
