The increasing impact of the network environment on image copyright makes research on the issue of SNS reproducing video copyright crucial for the copyright protection of China's network industry. This paper conducts a comparative analysis of copyright protection laws and regulations for SNS re-edited images in China and Germany across different historical periods. It also examines the copyright infringement liability system for user-generated content on video sharing websites. The study aims to develop a solution for copyright protection in the online video industry that meets China's national conditions, considering the responsibility of infringing users, the identification system of infringement liability of SNS re-edited video sharing websites, the legal compensation system, and the subjects of rights protection, combined with empirical analysis of relevant cases. Both Germany and China have defined corresponding legal responsibilities for users in cases of infringement. For example, Article 46 of the Copyright Law of the People's Republic of China specifies that if a user spreads copyrighted works on the internet without permission, the copyright owner may require the network service provider to take necessary measures to prevent the spread of the works. Similarly, German tort law requires users to undertake corresponding responsibility for their actions in cases of network torts. Therefore, both countries have similar rules regarding user responsibility in infringement cases. The results of the comparative analysis of copyright protection laws and regulations in China and Germany, with a focus on SNS reproducing video copyright, have significant implications for the copyright protection of China's network industry. The study ultimately aims to provide a suitable solution for copyright protection in the online video industry that aligns with China's national conditions.
