Vergence— un film de Tina Frank /

“Vergence”, un mot du domaine de l’optique lié à la convergence et à la divergence des rayons de soleil. Il indique aussi des mouvements lents et involontaires effectués par les yeux afin de centrer une image sur la rétine. Convergence et divergence déterminent la stabilité et la définition avec lesquelles un objet est perçu.
Ces définitions sont le point de départ du jeu optique rythmique réalisé par Tina Frank et Florian Hecker.

Vergence, a term from the field of optics, refers to the convergence or divergence of light rays. It also designates slow involuntary movements made by the eyes to center an image on the retina. Convergence and divergence determine the stability and definition with which an object is perceived.
Such dictionary definitions provide the point of departure for the rhythmic optical game of deception that Tina Frank and Florian Hecker initiate in their collaborative work entitled Vergence. The ratio of audio and video components are neither convergent nor divergent; expressed simply they overlap, move apart, then back together, accelerate each other, and so on. This sort of interlocking of sound and image repeats within both components, and as a result they remain autonomous to a great extent.

On the visual level, a black-and-yellow pattern of bars dissolves in stroboscopic flickering and movements in a number of different directions. The spaces this creates arch, spin, implode—this includes blow-ups, fades and zoom effects. In terms of the sound, a series of overlapping percussive patterns and pulses—in the form of throbbing, rattling, clattering, scraping and rattling—evoke the greatest possible variety of perceptive associations. Binaural, stereophonic and quadraphonic effects work together to break open systematically arranged auditory spaces: in front and behind, to the right and left, they run together unceasingly.
A finely constructed techno-psychedelic granular stream sweeps over the senses in Vergence, in an endless variety of modulations, concentrations and refractions. Hallucinogenic and evocative of images—until the colors come and the rhythms, seemingly endless, reverberate in the viewer’s mind.
