The trailer for the Unheard Film Festival is based on a visual representation of sound, and looks for the relationship between image and sound in a literal sense.
The trailer was finished in 2K and in the lead-up to the festival played in various cinemas.
In the trailer everything that makes a sound is represented as a sound wave and as the source of that sound. For example, a mouth is represented as a red wave rising to a crest when the voice is heard. The film was a live action shot that was later rotoscoped to define the waves appearing in it. In addition, colours accentuate the differences between various sound sources.
The film was shot in life action and rotoscoped to define the shapes in which the waveforms exist.
