Boom operator
The boom operator puts the microphone where the dialogue is, holds it there through the take, and keeps it out of frame and out of the light.
It is a physical craft that looks simple until you have done it for an eleven-hour day.

The job
What does a boom operator do?
You learn the scene and the lines, work out where each character will be and who speaks next, then swing the boom between them so every line is on-axis and close.
You watch the frame line, the shadow the boom is throwing, and the light you are about to cross. You also rig radio mics with the recordist, place plant mics, and cable the set.
The unglamorous end: arms above your head for hours, standing on an apple box against a wall, in the rain, being told the boom is in shot. Shoulders and elbows pay for this grade.
The requirement
What is a boom operator good at?
Anticipation, physical endurance and a memory for dialogue.
Anticipation
Knowing who speaks next before they do.
Frame awareness
Judging the frame line and the shadow from where you stand.
Stamina
Arms up, still, take after take.
Quiet feet
Moving through a set without adding a sound to it.
Rigging
Radio mics and plant mics hidden well enough to survive a wide shot.
Kit
Tools of the trade.
| What | The actual items |
|---|---|
| Poles | Carbon fibre boom poles, internally cabled and not, in several lengths. |
| Microphones | Sennheiser MKH 416 or 8060, Schoeps CMIT, hypercardioids for interiors. |

| Personal | Comfortable headphones, gloves, a folding step, and something to lean on. |

Routes in
How do I become a boom operator?
A grade you get by being trained by a recordist, more than by applying.
Sound trainee
The direct entry: cables, batteries, bags, then a pole.
Factual and corporate
Own a simple kit and boom real jobs immediately.
Music and live
Live engineers cross over with the ears already trained.
Shorts and student films
Where most boom operators learned to swing.
A degree is not required. An audio or music technology course helps with the theory, and is explicitly not essential to being hired.
A recordist who wants you back is the whole of the job market for this grade.
