Why is the Production Sound Mixer so important? What are some of their responsibilities in a film?
The saying goes that people will watch a movie with bad video, but will never sit through bad audio. Sound mixers are tasked with just that -- the recording and mixing of dialogue and other audio effects.
Two weeks before shooting, production sound mixers usually meet with the producer and director to confirm on creative intentions, financial statuses, and any equipment needs. Following this discussion, the production sound mixers will meet with the costume and visual effects departments to discuss microphone placement on the actors.
During production, the production sound mixers meet early to plan microphone choice, final placement of microphones on actors and the equipment that will be used by the boom operators to ensure the best quality possible.
