The primary role of a film editor is to assemble and arrange the shot footage into a coherent and cohesive sequence that tells the story and conveys the intended message of the film.

Cross-cutting is an editing technique where two or more shots of different subjects or locations are intercut to create a sense of parallel action or contrast. This technique is often used to build suspense, create a sense of urgency, or compare and contrast different characters or storylines.

A jump cut is an editing technique where two shots are abruptly joined together, creating a sense of disorientation or disruption. This technique is often used to create a jarring effect, emphasize a particular moment or action, or convey a sense of urgency or chaos.

Fade-in/Fade-out is an editing technique where one shot gradually fades out while simultaneously fading in the next shot. This technique is often used to create a smooth transition between scenes, indicate a passage of time, or create a sense of mystery or intrigue.

A dissolve is an editing technique where one shot gradually fades out while simultaneously fading in the next shot, creating a smooth and seamless transition between scenes. This technique is often used to indicate a passage of time, change in location, or to connect different storylines or characters.

Cut-on-action is an editing technique where one shot is cut to another shot of the same subject or scene, but from a different angle or perspective, as the subject performs a specific action. This technique is often used to create a sense of continuity and fluidity in the film's narrative.

The '180-degree rule' is a guideline in film editing that helps maintain continuity in the spatial relationship between characters and objects within a scene. It states that the camera should be positioned on one side of an imaginary line connecting two characters or objects, and should not cross that line during the scene, to avoid confusing the audience about the characters' positions relative to each other.

Match cuts are editing techniques where two shots are joined together based on a visual or thematic similarity between the two shots. This technique is often used to create a smooth transition between scenes, emphasize a particular moment or action, or to create a sense of continuity and coherence in the film's narrative.

Associative editing is an editing technique where two shots are joined together based on a visual or thematic similarity between the two shots, but not necessarily continuous in time or space. This technique is often used to create a sense of emotional or psychological connection between two scenes, or to convey a deeper meaning or symbolism within the film.

Rhythmic editing is an editing technique where the length, pacing, and rhythm of the shots are used to create a sense of pace and momentum in the film. This technique is often used to build tension, suspense, or excitement, or to create a particular mood or atmosphere.

Oppositional editing is an editing technique where two shots are joined together based on a visual or thematic contrast or opposition between the two shots. This technique is often used to create a sense of tension, conflict, or irony, or to emphasize the differences between two characters or situations.

Montage is an editing technique where a rapid succession of shots is used to convey a passage of time, a series of events, or a particular mood or atmosphere. This technique is often used to condense time, create a sense of rhythm or momentum, or to convey information quickly and efficiently.

Parallel editing is an editing technique where two or more shots are intercut to show different storylines or events that are happening simultaneously or in parallel. This technique is often used to create a sense of tension, suspense, or excitement, or to compare and contrast different characters or situations.

Ellipsis is an editing technique where a portion of the story or action is omitted or condensed, creating a gap or jump in the narrative. This technique is often used to speed up the pace of the film, create a sense of mystery or intrigue, or to focus on specific moments or events.

Associative editing is an editing technique where two shots are joined together based on a visual or thematic similarity between the two shots, but not necessarily continuous in time or space. This technique is often used to create a sense of emotional or psychological connection between two scenes, or to convey a deeper meaning or symbolism within the film.
