Film as cultural heritage is a concept that defines the historical and social relevance of cinematic works beyond their commercial value. This perspective, promoted by institutions such as UNESCO and FIAF, establishes that films are documents of the era in which they were created, reflecting political, technological, and artistic contexts. The conservation of this heritage is not limited to the physical preservation of copies, but includes restoration, digitization, and accessible dissemination. In this framework, film libraries and film museums act as guardians of audiovisual memory, ensuring that future generations can access these works. The entity encompasses both classic and contemporary productions, recognizing that heritage value is built over time and through critical reception. This approach transforms the film from an entertainment product into an intangible cultural asset that requires active protection and continuous academic study.
