Editing Film crew (section)

== Sound production ==
; [[Production sound mixer]]
: The production sound mixer (or sound recordist) is the head of the sound department on location and is responsible for the operation of the audio mixer and recorder(s) which receive feeds from the microphones on set. It is their responsibility to decide how they will deploy their team to capture the sound for each shot, select which microphones will be used for each setup, mix audio from all of the microphones in real time into a "mix track" that will be used while viewing rushes and during the edit, and sometimes in the final film, and to maintain logs of audio related issues for post production. The sound mixer is considered a department head, and is thus completely responsible for all aspects of production sound.
; [[Boom operator (media)|Boom operator]]
: The boom operator, first assistant sound or "1st AS", is responsible for using microphones on the end of boom poles (lightweight telescopic poles made of aluminium, or more commonly, carbon fibre) held above actor's heads during a scene to capture dialogue. It is also their responsibility to relay information from the "floor" back to the production sound mixer regarding upcoming shots, troublesome noises that the mixer will need to be made aware of if they can not be silenced, and for mounting radio microphones on actors. In France, the boom operator is called the [[perchman]].
; [[Utility sound technician|Second assistant sound]]
: The second assistant sound, utility sound technician, or "2nd AS", is the assistant to the boom operator and is responsible for moving and preparing sound equipment for use around the set while the boom op watches rehearsals and prepares for the next shot, as well as handling wireless audio feeds to the director, script supervisor and producers, and laying carpet and other sound dampening materials in locations with problematic floors or a troublesome acoustic. In addition, the 2nd AS is regularly called upon to operate a second boom in scenes with a larger number of actors or where actors are physically spaced too far apart for the 1st AS to cover all of the dialogue with one microphone. The 2nd AS also regularly aids in the radio mic'ing of cast when there are a large number of actors in a scene. The term "sound utility technician" is now considered an outdated term by [[Broadcasting, Entertainment, Communications and Theatre Union|BECTU]] in the UK and 2nd AS is preferred, with sound utility technician as a role being omitted from recent versions of the rate card.<ref>{{Cite web |url=https://www.bectu.org.uk/advice-resources/library/1568 |title=Sound Branch 'Production Sound' Ratecard (Published January 2016) – BECTU |access-date=May 8, 2016 |archive-url=https://web.archive.org/web/20160603005305/https://www.bectu.org.uk/advice-resources/library/1568 |archive-date=June 3, 2016 |url-status=dead }}</ref> The role is sometimes informally known as a "cable wrangler" or "cable boy".
