Montage editing involves juxtaposing short shots to represent ideas through techniques like repetition, rhythm, and metaphor. Pioneered by Soviet filmmakers in the 1920s-1930s like Eisenstein, montage aims to disorient the viewer through non-linear cutting in contrast to continuity editing. When constructing a montage, editors should vary shot durations, employ techniques like freeze frames or speed adjustments, use multiple visual layers, and ensure sound design supports the montage structure rather than following a strict beat. Montage aims to add shots rather than subtract them through disorienting and symbolic associations between images.
