In sound cinema, editing does not simply involve arranging the sequence of images but also assembling images and sounds.
Audio-visual editing has given rise to a wide range of effects based on the synchrony or disjunction between image and sound.
This session focuses on some of these effects.
Diegetic sounds usually coincide with what the images show.
But editing and sound mixing can create effects of spatial-temporal disjunction:
- Diegetic voice-over commenting images from the past,
- Sound bridges between two sequences,
- Intrusion on the image of one scene by the sound from another scene, particularly in the case of crosscutting.
Like image editing, audio-visual editing can produce rhetorical effects analogy, emphasis, discrepancy, counterpoint.
Most of these effects rely on the use of off-sounds, including noises, voices or music.
