Sound Meets Picture

In film sound mixing, dialogue, music, and effects are placed so they hit at the exact moment they should on screen. Mixers line up each sound with the picture, then balance how loud each one is.

In the picture

  1. A film frame: one moment of the picture that a sound is matched to.
  2. A waveform on a track: the shape of one sound from start to finish.
  3. A fader: the control for one track’s loudness.
  4. Headphones: the monitor for hearing the final blend.

Examples

  • A door slam in a scene is moved a few frames earlier so it hits when the door closes.
  • A song swells under a quiet conversation, then drops when the talking stops.

    • A sound’s alignment with the picture

    • One track’s loudness
  3. Why can a small timing shift of a few frames matter in film sound mixing?

    • It can make a sound feel natural or wrong
