Whether it is a form of experimentation with the possibilities of cinema, or as a way to get around the constraints of a traditional production, or the immediate result of an increasing ease of sharing a work with the public through new technologies, there are several examples, from works presented at festivals such as Yorgos Lanthimos ("Nimic"), the recording of a cinematic trip by João Pedro Rodrigues ("Potemkin Steps") and José Luis Guerin ("De una Isla") or even Jonathan Glazer's film ("The Fall") which interrupted the BBC's broadcast. 

For many it is a return to a format they adopted at the beginning of their career, a path from short to feature that is part of a director's normal journey. 

It is this path that allows shorts to be a window to the future of their authors, a reflection of a defining time of their cinema.
