At present, users, creators, and platforms jointly participate in the production and dissemination of audiovisual culture, building a distinctive content system and cultural ecology. How to provide users with better quality content has become a common problem faced by platforms and creators. Recently, some online video platforms have introduced measures aimed at promoting algorithms towards excellence, including multiple initiatives to integrate and mine high-quality content. Taking Bilibili as an example, it is explicitly proposed to deeply investigate the creative ecology of content creators (content creators), select high-quality articles with insight, warmth, knowledge, and enthusiasm, and prioritize their promotion and exposure, guiding the creation of the entire site towards excellence. At the same time, it is also proposed to invite relevant departments and authoritative professional institutions to provide theoretical and professional guidance for content creators. With the support of the platform, the vitality of creators can be released to a greater extent. At present, many online video platforms have unique content creators constantly emerging. Tiktok and Kwai mainly focus on vertical screen short videos, while Bilibili mainly focuses on horizontal screen medium and long videos. Not long ago, Bilibili announced the list of the Top 100 UP Owners for 2024, with 4 people winning the title for the 7th consecutive year. Nearly 90% of the Top 100 UP Owners have been updated on Bilibili for more than 5 years. From this, it can be seen that UP creators who focus on creating high-quality medium to long videos for a long time are more likely to gain user love. These professional, influential, and innovative UP hosts meet people's diverse cultural needs. Some university professors have stepped out of their ivory towers and become well-known creators with millions of followers. For example, Professor Dai Jianye from Central China Normal University has set up a "Poetry Writing Genius" column to challenge users and attract many young people to actively "submit assignments". Ancient poetry themed videos have become a space for young people to exchange knowledge and showcase themselves. Professor Luo Xiang from China University of Political Science and Law's "Luo Xiang Talks about Criminal Law" series of videos not only analyzes hot events, but also often "leads by reading classics", inspiring and guiding viewers to draw wisdom behind the law. Creators from all walks of life are also using their professional knowledge and skills to provide people with exquisite "internet spiritual food". For example, Muyu Shuixin, who has been listed as one of the top 100 UP hosts for seven consecutive years, completed the explanation of some ancient Chinese history in "Records of the Grand Historian" with documentary quality in 2024, and the total online views exceeded 200 million. At the same time, online video platforms are also spaces for young people to showcase and record their individual lives. Users interact with UP hosts in the form of likes, shares, comments, collections, etc., meeting each other's needs of "wanting to be seen" and "seeing more", collectively creating a new atmosphere of contemporary life aesthetics. For example, the UP host LinksPhotograph uses a camera to record cultural landscapes, from the dreamy starry sky of Mount Gongga in Sichuan to the permafrost of Iceland, constantly inspiring people's expectations for the distance. UP host Thief Moon Social Food Encounter leads the audience through food culture, seeing the customs and traditions of different regions, and experiencing the simple and unadorned emotions between people. Creators from different fields have demonstrated the diversity and richness of life, spreading a positive, resilient, and upward attitude towards life; All generations of image producers share their aesthetic styles and creative experiences, and different aesthetic spaces of life blend and enhance each other, promoting creativity and innovation in the cultural and artistic fields. Online video is a new form of literature and art promoted by the Internet and digital technology. Content creators with a large number of fans should "dedicate the best spiritual food to the people". Eliminating the bad and preserving the good, promoting the good and eliminating the bad, and striving for excellence and goodness should be the philosophy of every platform and content creator. Only in this way can online audio-visual content bloom brilliantly in the garden of literature and art. (New Society)
