Video editing

Video editing is the post-production process of selecting and combining video shots to create a finished piece. Editors work with raw footage, trimming clips, arranging them in sequence, and adding transitions, titles, and sound. The goal is to serve the story or message, controlling pacing and guiding the viewer's attention. Modern editing is typically done on non-linear editing (NLE) software, which allows random access to any part of the footage, unlike linear tape-to-tape editing. Key tasks include cutting, splicing, color correction, and audio mixing.¹

The earliest film editing was done by physically cutting and splicing celluloid film. The first notable use of editing for narrative effect is often attributed to Edwin S. Porter's The Great Train Robbery (1903), which used cross-cutting to build suspense. The 1920s saw the development of continuity editing, codified by Soviet filmmakers like Sergei Eisenstein, who used montage to create meaning. The introduction of magnetic tape in the 1950s allowed electronic editing, and the 1970s brought the first digital editing systems, such as the CMX 600. The 1990s saw the rise of NLE software like Avid and Final Cut Pro, which revolutionized the field by making editing faster and more accessible.²

Editors employ a range of techniques to shape the viewer's experience. The cut is the most basic edit, but its placement can create continuity or discontinuity. The 180-degree rule and match on action help maintain spatial coherence. Montage sequences compress time and convey information rapidly. Transitions like dissolves and wipes have stylistic connotations; for example, a dissolve often signals a passage of time. Editors also use rhythm and pacing to evoke emotion, as seen in the rapid cutting of action scenes or the long takes of art cinema. Color grading and sound design are integral to the final look and feel.

In professional productions, editing is a collaborative effort. The editor works closely with the director to realize the vision, and may be assisted by assistant editors who organize footage and prepare sequences. The workflow typically involves logging and syncing footage, creating a rough cut, then a fine cut, and finally the picture lock, after which sound and visual effects are added. Editors must have a keen sense of storytelling, technical proficiency with software, and the ability to work under tight deadlines. In documentary and reality TV, editors often shape the narrative from hours of footage, a role that requires strong editorial judgment.³

Beyond the mainstream, video editing has niche applications and historical oddities. For instance, the first use of editing for propaganda was in Soviet films like Battleship Potemkin (1925), which used montage to evoke emotion. In the 1960s, the French New Wave directors like Jean-Luc Godard used jump cuts to break conventions. The term 'invisible editing' refers to the Hollywood style that hides cuts to maintain realism. In the digital age, editing has expanded to include 360-degree video and virtual reality, requiring new techniques. Also, the role of the editor was historically underrecognized; it wasn't until the 1930s that editors received screen credit.⁴

Non-linear editing (NLE)

A system that allows random access to video clips on a timeline, enabling flexible editing without physical cutting.

Montage

A sequence of shots edited together to condense time or convey a concept, often associated with Soviet film theory.

Jump cut

An abrupt cut that creates a discontinuity in time or space, often used for stylistic effect.

Continuity editing

A style of editing that aims to maintain a coherent and logical flow of action, using techniques like the 180-degree rule.

Rough cut

An early version of a film edit that is not yet polished, used to assess the overall structure.
