This book has been conceived from a series of speeches which took place during the Filmforum Festival of Udine and Gorizia whose main theme was the use of moving images in the space of contemporary art. The aim of this publication is to create a scientific framework of some of the most important artistic experiences: from the use of archive images to the newest participatory practices. The book consists of essays selected during the Filmforum Festival and the MAGIS International Film Studies Spring School and texts from invited researchers. It examines the ways in which the transient qualities of time have been used in contemporary moving images production and in their display.
