712 RD 2

This title appears to be a specific experimental or amateur film, likely associated with the 1974 piece attributed to the avant-garde tradition or an individual artist's catalog. In the case of films from 1964–1977, copyright renewal is automatic under the 1992 Amendment; however, the work's protection status is contingent on it having been published with a valid copyright notice. A search of the United States Copyright Office online database (which contains records from 1978 forward) and the Stanford Copyright Renewals database yields no registration or renewal documentation for a film titled '712 RD 2'. Because it was produced during the 'notice window' (1964–1977), its status as public domain would depend on whether it was distributed without a proper notice (17 USC §405). Given the likely non-commercial or experimental nature of the title, it is highly probable it was never formalised with a registration, but the absence of evidence regarding its publication/notice status makes a definitive 'public domain' or 'protected' determination impossible.
