Multiple images displayed simultaneously on screen — split-screen, picture-in-picture, or mosaic layouts. Gance pioneered it in 1927; essential for simultaneous action in thrillers and modern interfaces.
Showing multiple image streams simultaneously in editing – that is the core of Polyvision. Not simply montage one after another, but spatially separated, simultaneous images on one screen or a display. Nothing special happens on set; the trick lies in post-production and the visual design, which must already be considered during shooting.
The classic application: split screen. Action on the left, reaction on the right – both visible at the same time. This creates tension through comparison, parallel, or contrast. Phone calls work elegantly with it: caller and receiver in their respective spaces, the eye jumps back and forth without us feeling a cut. With picture-in-picture layouts, a smaller screen sits in the corner. Common for surveillance camera shots or when we are meant to follow two plotlines simultaneously without hard cuts.
Abel Gance was the pioneer in 1927 – Napoléon used triptych projections, three images side-by-side. That was revolutionary for its time; today we see Polyvision everywhere: thriller sequences use split-screen to enhance pursuit or tension. Andy Warhol experimented with it in his films to make boredom and everyday life visible – multiple identical or different takes in parallel. TV episodes, especially crime and action series, constantly resort to it.
Practical on set: If you know that footage will be split later, you pay attention to framing and lighting for each composition separately. A split-screen needs two well-lit, interesting images side-by-side – poorly framed content is unconsciously perceived, even if it only occupies half the screen. Audio design becomes more complex: two spaces, two soundscapes that must not clash.
Today, Polyvision is standard in streaming and apps – dashboard aesthetics everywhere. The editing suite offers countless options: mattes, keys, dynamic window sizes. The viewer gets used to reading and watching in parallel. This changes the narrative speed: more information in less time, but also higher cognitive effort. Use it consciously – not as a gimmick, but as a narrative structure.
