Tarkovsky opposed to the movie editing and considered that the basis of the art of cinematography (movie art) is the internal rhythm of images. He considers cinema as a representation of distinctive currents or time waves, transmitted in the film through its internal rhythm. Rhythm is at the heart of the "poetic film". A rhythm like a movement inside the frame ("sculpting in time"), not as a sequence of images in time. Time within the frame expresses something significant and true that goes beyond the events itself, received differently by each spectator. The rhythm is not determined by the length of the sequences, but by the pressure of time passing through them.
