Cinema that makes time itself the subject — not compressing it, but stretching, manipulating, or examining how we perceive it. Slow film, durational work.
Time here is not simply depicted—it becomes material. Time-based cinema consciously works against the classic editing pace, against the narrative compression we know from mainstream cinema. Instead, it stretches sequences, lets the camera stand still, and accepts emptiness and stillness as dramatic elements. This is not boredom, but a different negotiation between viewer and movement.
In practice, this means: a 7-minute shot of an empty room where nothing happens becomes an act of attention. The camera is not filming for something—time itself becomes the statement. Yasujirō Ozu did this masterfully: his pillow shots linger on locations that the action has long since left. Michael Snow, Chantal Akerman, Agnes Varda in their more experimental phases—they all used duration as a formal statement. On set, this means: patience with the take, no nervous checking of the clock. In the edit then: Resist the urge to trim. The length is the point.
This fundamentally differs from mere slowness. Slow Cinema (see there) can certainly be narrative—think of Lav Diaz or Béla Tarr, where time is stretched but functions psychologically or atmospherically. Time-based cinema in the true sense abstracts even further: time becomes structure, a perceptual machine. This variant is also called duration film—every second counts because all seconds are equally valid.
Practically, this is a conscious counter-strategy to audience expectations. No tension through editing rhythm, no drama through montage tension. Instead, presence emerges. You sit within the image, rather than consuming it. This demands a rethinking from the audience—and from you as a filmmaker, absolute certainty in your creative decisions. Every second without editorial justification must be deliberate.
