Audiovisual works (or motion pictures), in comparison to other copyrighted works, are works with complicated rights and obligations. Comparing copyright laws across the world becomes an essential task for the purpose of responding to our legislative needs. Despite discrepancies in the evolution of the legislative developments, copyright legislations on both sides of the Strait are still yet to be deemed as full-fledged and mature laws. The process of relentlessly discovering questions and solving problems continues as we apply the laws and exchange views. Both sides across the Strait share similar situation in this aspect.This paper compares the copyright laws on both sides of the Strait in relation to audiovisual works (or motion pictures). The preliminary conclusion is that Taiwan copyright law needs to address the issues of protecting audio and visual recordings, a right that is recognized by copyright laws in China, Germany and France.In addition, copyright laws on both sides of the Strait ought to, by modeling after the Japanese and French copyright legislations, clearly define the ”author” of a visual-audio work (or motion picture). Taiwan Copyright Law ought to clearly define the ownership of audiovisual works. The best option is to adopt the ”Legal Transfer Model” (Legal Ownership Model). Furthermore, the moral rights covered in Article 15 of the P.R.C. Copyright Law may give rise to contradictory applications of the rule. The underlying legislative theory demands further examination.Finally, the term of protection for the economic rights subsisting in audiovisual works (or motion pictures) is different from the term of protection for the pre-existing works of which the audiovisual works are consisted (e.g. novels, scripts, music scores, et cetera). In the event that the term of protection for an audiovisual work expires prior to that of its pre-existing component works, a question arises as to whether using the audiovisual work could potentially infringe the pre-existing works 'authors' copyright. Article 54 of Japanese Copyright Law is legislated in a way that clearly addresses this issue and may be used as a reference for copyright legislations on both sides of the Strait.
