Split screen

A film technique that displays two or more images simultaneously within one frame. It can present parallel actions, multiple viewpoints, or a visual comparison.

Compositing: The combining of visual elements from separate sources into a single image. Split screen combines separately framed images within one film frame.
Timecode: A numeric code used to identify particular frames or moments in audiovisual media. Matching timecodes helps align simultaneous events across split-screen panels.
Early cinema: The period and practices of filmmaking from cinema's beginnings through the early twentieth century. Early filmmakers explored ways to show multiple views within one image.
Multiple exposure: A photographic or cinematographic technique that records more than one exposure on the same image area. Multiple exposure superimposes images rather than separating them into panels.
Film editing: The process of selecting, arranging, and joining shots to shape a film. Editors coordinate split-screen panels with cuts, pacing, and sound.
Telephone scene: A dramatic scene in which characters communicate by telephone, often from separate locations. Split screen can show both ends of a conversation at once.
Georges Méliès: A French filmmaker and stage magician known for pioneering cinematic special effects and fantasy films. Méliès used multiple exposures and masking effects related to split-screen construction.
Superimposition: The layering of two or more images so they appear together in a single frame. Split screen preserves distinct image regions, while superimposition layers them.
Matte (filmmaking): A mask or painted image used to control which parts of a film frame are exposed or combined. Matte techniques can define the boundaries between simultaneous images.
Parallel editing: An editing technique that alternates between actions occurring in different places, often implying simultaneity. Split screen makes parallel action visible simultaneously rather than alternating shots.
