The boom operator gets the microphone as close as the frame allows.

The job

You hold the main boom above or below the actors, as close as the frame allows, and move it with the dialogue. On UK drama this is usually the 1st assistant sound, who runs the department on the floor while the mixer's at the cart.

You agree boom positions with the operator and gaffer to stay out of frame and out of the lamps. You also support the mixer with kit, radio mics and the sound report.

A typical day

• Set up the boom and check kit with the sound assistant.
• At blocking, watch the actors and dialogue and pick your position.
• Check frame lines with the operator and shadows with the gaffer.
• During takes, move with each line, listening on cans.
• Between setups, plan the next position. At wrap, pack the boom and help the mixer.

Nobody notices a boom in the right place. Everybody notices a dip in frame or a shadow on the wall. Sort it with the operator and gaffer before the take, not after.

Skills

• Reading frame lines and anticipating dialogue.
• Strength and stamina to hold a boom through long takes.
• Knowledge of microphones and their pick-up patterns.
• Diplomacy with camera, lighting and cast.
• Knowing the script.

Who you report to
