Continuity refers to action moving through multiple locations without interruptions. It usually refers to the degree to which a film is self-consistent without errors, jump cuts, or mismatched shots and details.

The final edited structure of a completed film includes events or scenes/sequences arranged as if they had occurred continuously, when, in fact, they were shot out of sequence.

In the early 20th century, a system of editing was developed to provide a continuous and clear movement of events/images. A continuity cut refers to an editing cut that takes the viewer seamlessly, unobtrusively, and logically from one sequence or scene to another, to propel the narrative along. A blooper or flub is a continuity error.
