In short: A boom operator holds the microphone on a long pole, out of shot, and keeps it as close to the speaker as the frame allows. They rehearse with the actors and camera, work under the sound mixer, and watch for shadows and reflections. If you need a boom at Granary, say so when you enquire. A sound recordist from £495 a day +VAT is on the crew rate card.
A boom operator holds the microphone on a pole, just out of shot, and places it as close to the speaker as the frame allows. The position is precise, and the boom has to move with the actors without ever appearing in the picture or making a noise.
What a boom operator does on a shoot day
- Rehearse the moves. Walk the scene with the actors and the camera team so the boom can follow the blocking.
- Find the frame lines. Know where the edge of the shot is at every point, so the microphone stays outside it.
- Place the microphone. Get it close to the speaker, angled to pick up the voice and not the room behind.
- Watch the shadows. A microphone or pole can throw a shadow on the set or the actor. Move before the take, not during it.
- Follow the take. Keep the boom steady and move with the speaker, and hold position when the actor pauses.
- Confirm with the sound mixer. The mixer checks the levels from the radio and boom microphones on every take and says when a take needs another go.
The boom operator's work is mostly invisible. A good one is noticed only when a scene sounds right.
Who they work with
The boom operator works under the sound mixer, who leads the sound department and records mainly dialogue. The sound mixer plans the approach with the producer and director, and checks the levels from every microphone. The boom operator also works with the sound trainee, who helps set up and looks after batteries, cables and kit, and with the camera team on the frame lines.
ScreenSkills describes the sound trainee as reporting to the sound mixer and working with the boom operator. For the sound side of a shoot, see what a sound assistant does and what a production sound mixer does.
Kit and skills
The boom operator works with a pole, a shock mount and a windshield, usually part of the sound department's kit. The sound mixer chooses the microphone. At Granary we record dialogue with lapel microphones. If a job needs a boom, ask when you enquire.
Skills that matter most:
- Holding a pole steady for long periods without letting the microphone drift.
- Reading a scene and anticipating the actor's movement.
- Working quietly, with the set and the actors aware of every move.
- Good listening, so you hear a noise before the mixer does.
- Stamina, because a boom is heavy after a long day.
How to become a boom operator
ScreenSkills describes sound careers as starting with a trainee role, so most boom operators begin as sound trainees. It lists these routes:
- Trainee roles. Apply through ScreenSkills' Trainee Finder, or ask a kit hire company about trainee places.
- Qualifications. Level 3 sound or music technology courses are useful, as are A-levels or Highers in maths, physics and music for a university route.
- Short courses. The National Film and Television School runs a location sound recording course.
- Experience. Build a portfolio through student films and a showreel, and work for a kit hire company to learn the equipment.
Apprenticeships exist but places are limited. ScreenSkills also suggests joining its events and networking on LinkedIn. Bectu, the media and entertainment union, takes members at the start of their careers and offers advice on problems at work, so it is worth looking at once you start getting booked.
Do you need one on a small shoot?
- A single presenter or interview with a lapel microphone: usually not. A lapel gives a clean voice without a boom.
- Several people talking in one shot, or a scene with no lapels: yes, a boom gives the most natural sound.
- A scripted scene with movement: usually yes. A boom operator is worth the day rate.
Our sound and post-production page describes the audio services we offer. Granary's indicative rate for a sound recordist starts from £495 a day +VAT. For a boom operator, ask us for a quote.

Questions we get asked

Do you need a boom operator on a small shoot?
Not for a single presenter wearing a lapel microphone. A boom helps when several people talk in one shot, when the scene has no lapels, or when the production wants a natural room sound.
