The document outlines six priorities for a production mixer when recording audio on set: 1) Getting usable dialogue is the top priority. 2) Maintaining proper audio perspective to match the camera viewpoint. 3) Syncing sound effects without compromising dialogue. 4) Recording wild lines and off-camera dialogue for coverage. 5) Capturing wild sound effects not available in libraries. 6) Recording ambiance and room tone to patch holes in the edited soundtrack.
