1. (book publishing) A role involving the commissioning of new books and the coordination of their creation and production. A copy editor checks manuscripts for errors and consistency ready for printing.
2. In the compilation of edited books and the production of journals, the role of coordinating the work of contributors.
3. (periodical publishing) A role involving the overall control of content, format, and publication.
4. (film) A role involving logging, cutting, and assembling film rushes into a presentable form (although today it is invariably done using a nonlinear editing system). An editor usually makes decisions in close association with the director, or sometimes the producer.
5. In video and audio post-production, a role that is very similar to a film editor, but using videotape or audio recordings instead of film.
