Definition of block out

The term "block out" has its origins in the film and theater industries, where it refers to the preliminary stages of creating a visual or theatrical piece. In films, "blocking" refers to the arrangement of actors and camera movements in a shot. This process helps the director and cinematographer visualize how the scene will play out and allows them to plan for camera angles and movements. "Blocking out" is the initial phase of blocking, when actors and crew members roughly sketch out the positions and movements they'll make during the scene. In theater, "blocking" refers to the movement patterns that actors follow during their performances. Blocking out is done during rehearsals and helps actors understand where they'll move and when. Throughout the blocking process, actors make notes on their scripts, outlining where they need to move during each line or scene. The final product is a series of notes and diagrams that the actors can follow during a performance for fluid, orchestrated movement. The concept of "blocking out" is also used more broadly to mean eliminating other elements or people from a space or task. In construction, "blocking out" refers to enclosing a certain area or space with formworks or temporary barriers to set up the structure's foundation or walls. In writing or editing, "blocking out" may mean removing excess material or details to help focus on the essential elements of the piece. In each context, blocking out serves another stage in a larger process, helping to refine and improve the final product by clarifying movement, installing temporary barriers, or eliminating superfluous material.
