The term "B-roll" is now limited to secondary footage that adds meaning to a sequence or disguises the elimination of unwanted content. This technique of using the cutaway is common to hide zooms in documentary films: the visuals may cut away to B-roll footage of what the person is talking about while the A camera zooms in, then cut back after the zoom is complete. The cutaway to B-roll footage can also be used to hide verbal or physicaltics that the editor and/or director finds distracting: with the audio separate from the video, the filmmakers are free to excise "uh"s, sniffs, coughs, and so forth. Similarly, a contextually irrelevant part of a sentence or anecdote can be removed to construct a more effective, succinct delivery. This can also be used to change the meaning of the speaker to fit the view of the producer. In fiction film, the technique can be used to indicate simultaneous action or flashbacks, usually increasing tension or revealing information.
