What do music, sound effects, dialogue, international sound and mixing mean respectively?

Music refers to the background music in the film, which mainly plays the role of setting off the atmosphere, describing the characters' personality and promoting the development of the plot. Generally divided into active music and passive music. Active music refers to music that can be traced back to the source, such as the music from the speakers in the picture, which mainly reflects the real situation. Passive music is equivalent to voice-over, which mainly sets off the atmosphere and describes the plot and the characters' hearts.

Sound effect refers to sound effect, which can be roughly divided into two categories: realism and design sense. Realism is mainly composed of onomatopoeic words, which restores the sound of pictures that are difficult to record in reality. There are also some sound effects full of design sense, such as the monster cries in science fiction movies, which need to be designed by synthesizing sound. Sometimes the lens language of the picture will be accompanied by sound effects, such as the bullet time slow motion in The Matrix will be accompanied by low-frequency sound effects to express the time ban.

Dialogue refers to the voice of the characters in the picture. Generally speaking, the later stage of dialogue can be divided into record and ADR record according to the mouth shape.

International pronunciation refers to the dialogue in the picture. If the film is planned to be released overseas, it is necessary to make a multilingual version of the dialogue so that the local voice can be made when it is released overseas.

Mixing refers to the reasonable collocation of channel materials such as music, sound effects, dialogue and international sounds, including the perfect integration of loudness and frequency bands, so as to achieve the harmonious integration of these elements.
