Which term refers to creative work that is not under copyright and can be freely used?

Public domain refers to creative work that is no longer under copyright protection, allowing anyone to use, reproduce, and modify the material without seeking permission or paying royalties. Works can enter the public domain for several reasons, such as the expiration of copyright protection, deliberate designation by copyright holders, or the nature of the work itself, such as government publications.

Understanding public domain is crucial for creators and producers, especially in video production, as it allows for the use of materials that can enrich a project without legal issues or costs associated with copyright. This is particularly useful for filmmakers looking for resources like music, literature, or visual arts to incorporate into their projects while avoiding licensing fees.

The other choices represent different concepts. Open source generally refers to software whose source code is made available for modification and distribution, but it does not apply to all types of creative work. Exclusive rights pertain to the privileges granted to copyright holders, allowing them to control the use of their work. Creative Commons provides a variety of licensing options that enable creators to share their works while retaining some degree of copyright protection, which is different from work that is entirely in the public domain.
