Editing B-roll (section)

==Film and video production==
Films and videos may [[Cutaway (filmmaking)|cut away from the main story]] to show related scenery or action. [[Establishing shot]]s may be used to show the audience the context of the story. These secondary images are often presented without sound, or with very low level sound, as the sound from the primary footage is expected to continue while the other images are shown. The various shots presented without sound are called ''B-roll''.<ref name="Irving and Rea 2014">{{cite book |url=https://books.google.com/books?id=6pvcAwAAQBAJ&pg=PA172 |page=172 |title=Producing and Directing the Short Film and Video |first1=David K. |last1=Irving |first2=Peter W. |last2=Rea |publisher=CRC Press |year=2014 |isbn=9781136048425}}</ref>

B-roll may be shot by smaller [[second unit]] crews, since there is no need for sound. In film, smaller [[MOS (filmmaking)|MOS]] cameras, lacking sound circuitry, may be used for greater portability and ease of setup.<ref name="Irving and Rea 2014"/> In [[electronic news-gathering]] (ENG) and [[documentary film]] projects, B-roll footage is often shot after the main interview is shot, to provide supporting scenes for what was said by the interview subject.<ref name="Compesi and Gomez 2014">{{cite book |url=https://books.google.com/books?id=K5vhCgAAQBAJ&pg=PA268 |page=268 |last=Compesi |first=Ronald |last2=Gomez |title=Introduction to Video Production: Studio, Field, and Beyond |publisher=CRC Press |date=2015 |isbn=9781317347156}}</ref> In a [[docudrama]] project, B-roll may refer to dramatic re-enactment scenes staged by the producer and performed by actors, to be used as cutaway shots.<ref name=Wales2017>{{cite book |url=https://books.google.com/books?id=giglDwAAQBAJ&pg=PA17 |page=17 |last=Wales |first=Lorena M. |title=The Complete Guide to Film and Digital Production: The People and The Process |publisher=Taylor & Francis |date=2017 |isbn=9781315294889}}</ref>
