In filmmaking, the 180-degree rule [1] is a basic guideline regarding the on-screen spatial relationship between a character and another character or object within a scene. The rule states that the camera should be kept on one side of an imaginary axis between two characters, so that the first character is always frame right of the second character. Moving the camera over the axis is called jumping the line or crossing the line; breaking the 180-degree rule by shooting on all sides is known as shooting in the round.
The 180-degree rule enables the viewer to visually connect with unseen movement happening around and behind the immediate subject and is particularly important in the narration of battle scenes.
In a dialogue scene between two characters, a straight line can be imagined running through the two characters. If the camera remains on one side of this line, the spatial relationship between the two characters will be consistent from shot to shot. Shifting to the other side of the characters on a cut will reverse the order of the characters from left to right and may disorient the viewer.
The rule also applies to the movement of a character as the "line" created by the path of the character. For example, if a character is walking in a leftward direction and is to be picked up by another camera, the character must exit the first shot on frame left and enter the next shot frame right.
A jump cut can be utilized to denote time. If a character leaves the frame on the left side and enters the frame on the left in a different location, it can give the illusion of an extended amount of time passing.
Another example could be a car chase: If a vehicle leaves the right side of the frame in one shot, it should enter from the left side of the frame in the next shot. Leaving from the right and entering from the right creates a similar sense of disorientation as in the dialogue example.
The imaginary line allows viewers to orient themselves with the position and direction of action in a scene. If a shot following an earlier shot in a sequence is located on the opposite side of the 180-degree line, then it is called a "reverse cut". Reverse cuts disorient the viewer by presenting an opposing viewpoint of the action in a scene and consequently altering the perspective of the action and the spatial orientation established in the original shot. [2]
There are a variety of ways to avoid confusion related to crossing the line due to particular situations caused by actions or situations in a scene that would necessitate breaking the 180-degree line. The movement in the scene can be altered, or cameras set up on one side of the scene so that all the shots reflect the view from that side of the 180-degree line. [2]
Another way to allow for crossing the line is to have several shots with the camera arching from one side of the line to the other during the scene. That shot can be used to orient the viewer to the fact that they are looking at the scene from another angle. In the case of movement, if a character is seen walking into frame from behind on the left side walking towards a building corner on the right, as they walk around the corner of the building, the camera can catch them coming towards the camera on the other side of the building entering the frame from the left side and then walk straight at the camera and then exit the left side of the frame.
To minimize the "jolt" between shots in a sequence on either sides of the 180-degree line, a buffer shot can be included along the 180-degree line separating each side. This lets the viewer visually comprehend the change in viewpoint expressed in the sequence. [2]
In professional productions, the applied 180-degree rule is an essential element for a style of film editing called continuity editing. The rule is not always obeyed. Sometimes a filmmaker purposely breaks the line of action to create disorientation. Carl Theodor Dreyer did this in The Passion of Joan of Arc ; Stanley Kubrick also did this, for example, in the bathroom scene in The Shining . [4] Directors Jacques Demy, Tinto Brass, Yasujirō Ozu, Wong Kar-wai, and Jacques Tati have also ignored this rule sometimes, [5] as has Lars von Trier in Antichrist . [6] In the seminal French New Wave film À bout de souffle (Breathless), Jean-Luc Godard breaks the rule in the first five minutes in a car scene which jumps between the front and back seats, improvising an "aesthetic rebellion" for which the New Wave would become known. [7] When the rule is broken accidentally, or for a technical reason (such as the inability to place a camera physically in the correct position), there are techniques which may be employed to attempt to hide it. For example, the editor may pre-lap a word or two of dialog prior to the cut, so that the viewer will concentrate on what is being said as a distraction from the breaking of cinematic convention.[ citation needed ]
Some styles used with the 180-degree rule can elicit an emotion or create a visual rhythm. By moving the camera closer to the axis for a close-up shot, it can amp up the intensity of a scene when paired with a long shot. [8] When the camera is moved further away from the axis for a long shot after a close-up shot, it may provide a break in the action of the scene. [9]
In the Japanese anime feature Paprika , two of the main characters discuss, and demonstrate, the disorientating effect of crossing the line. [10]
Empirical evidence exploring the importance of maintaining the 180-degree rule is limited. [11] The basic premise is that abiding by the rule helps keep characters on the correct side of the screen. [12] Thus, it is assumed that if the rule is violated, it can lead to distraction [13] and disrupt the flow of the moment. [14] This is then extrapolated to affect the rhythm, or emotions of the scene. However, these notions are rooted in filmmakers' subjective reports, rather than empirical evidence. [11]
Some research has demonstrated that crossing the line can negatively affect the accuracy of spatial representation of the scene. [15] [16] Furthermore, flipping the characters' positions can disrupt the viewer's understanding of the relative orientations on screen. [17] Violations appear to also affect spatial memory for the location of objects in a scene, but they do not affect memory for the narrative, the order of unfolding events, [18] nor the understanding of narrative flow. [19]
Broadly speaking, empirical research indicates that abiding by the 180-degree rule is not necessary in a practical sense. Accurate spatial representations may not be important for the scene, nor are they remembered across the longer duration of a movie. [17] [20] Furthermore, more recent research has demonstrated that while viewers can spot violations, the presence of these violations has a negligible effect on the enjoyment of the scene or movie. [21]
Film editing is both a creative and a technical part of the post-production process of filmmaking. The term is derived from the traditional process of working with film which increasingly involves the use of digital technology. When putting together some sort of video composition, typically, one would need a collection of shots and footages that vary from one another. The act of adjusting the shots someone has already taken, and turning them into something new is known as film editing.
The film industry is built upon many technologies and techniques, drawing upon photography, stagecraft, music, and many other disciplines. Following is an index of specific terminology applicable thereto.
In cinematography, a tracking shot is any shot where the camera follows backward, forward or moves alongside the subject being recorded. Mostly the camera’s position is parallel to the character, creating a sideway motion, tracking the character. Tracking shots differ in motion from dolly shots, where the camera follows behind or before the character resulting in either an inward or an outward movement. Often the camera is mounted on a camera dolly which rides on rails similar to a railroad track; in this case, the shot is referred to as a dolly shot. A handheld steadycam or gimbal may also be used for smaller scale productions. The camera is then pushed along the track while the scene is being filmed, or moved manually when using a handheld rig. The effect can be used to create a sense of movement, to follow a character or object, or a sense of immersion to draw the viewer into the action.
A jump cut is a cut in film editing that breaks a single continuous sequential shot of a subject into two parts, with a piece of footage removed to create the effect of jumping forward in time. Camera positioning on the subject across the sequence should vary only slightly to achieve the effect. The technique manipulates temporal space using the duration of a single shot—fracturing the duration to move the audience ahead. This kind of cut abruptly communicates the passing of time, as opposed to the more seamless dissolve heavily used in films predating Jean-Luc Godard's Breathless, which extensively used jump cuts and popularized the technique in the 1960s. For this reason, jump cuts are considered a violation of classical continuity editing, which aims to give the appearance of continuous time and space in the story-world by de-emphasizing editing, but are sometimes nonetheless used for creative purposes. Jump cuts tend to draw attention to the constructed nature of the film. More than one jump cut is sometimes used in a single sequence.
A film transition is a technique used in the post-production process of film editing and video editing by which scenes or shots are combined. Most commonly this is through a normal cut to the next shot. Most films will also include selective use of other transitions, usually to convey a tone or mood, suggest the passage of time, or separate parts of the story. These other transitions may include dissolves, L cuts, fades, match cuts, and wipes.
In filmmaking and video production, a shot is a series of frames that runs for an uninterrupted period of time. Film shots are an essential aspect of a movie where angles, transitions and cuts are used to further express emotion, ideas and movement. The term "shot" can refer to two different parts of the filmmaking process:
Continuity editing is the process, in film and video creation, of combining more-or-less related shots, or different components cut from a single shot, into a sequence to direct the viewer's attention to a pre-existing consistency of story across both time and physical location. Often used in feature films, continuity editing, or "cutting to continuity", can be contrasted with approaches such as montage, with which the editor aims to generate, in the mind of the viewer, new associations among the various shots that can then be of entirely different subjects, or at least of subjects less closely related than would be required for the continuity approach. When discussed in reference to classical Hollywood cinema, it may also be referred to as classical continuity.
In filmmaking and photography, the Dutch angle, also known as Dutch tilt, canted angle, vortex plane, or oblique angle, is a type of camera shot that involves setting the camera at an angle so that the shot is composed with vertical lines at an angle to the side of the frame, or so that the horizon line of the shot is not parallel with the bottom of the frame. This produces a viewpoint akin to tilting one's head to the side. In cinematography, the Dutch angle is one of many cinematic techniques often used to portray psychological uneasiness or tension in the subject being filmed. The Dutch angle is strongly associated with German expressionist cinema, which employed it extensively.
Tilting is a cinematographic technique in which the camera stays in a fixed position but rotates up/down in a vertical plane. Tilting the camera results in a motion similar to someone raising or lowering their head to look up or down. It is distinguished from panning in which the camera is horizontally pivoted left or right. Pan and tilt can be used simultaneously. In some situations the lens itself may be tilted with respect to the fixed camera body in order to generate greater depth of focus.
Classical Hollywood cinema is a term used in film criticism to describe both a narrative and visual style of filmmaking that first developed in the 1910s to 1920s during the later years of the silent film era. It then became characteristic of American cinema during the Golden Age of Hollywood from about 1927, with the advent of sound film, until the 1960s. It eventually became the most powerful and pervasive style of filmmaking worldwide.
This article contains a list of cinematic techniques that are divided into categories and briefly described.
Screen direction is the direction that actors or objects appear to be moving on the screen from the point of view of the camera or audience. A rule of film editing and film grammar is that movement from one edited shot to another must maintain the consistency of screen direction in order to avoid audience confusion. Continuity Editing is an essential rule that filmmakers follow to push their narrative forward in a navigable manner.
A script supervisor is a member of a film crew who oversees the continuity of the motion picture including dialogue and action during a scene. The script supervisor may also be called upon to ensure wardrobe, props, set dressing, hair, makeup are consistent from scene to scene. The script supervisior keeps detailed notes on each take of the scene being filmed. The notes recorded by the script supervisor during the shooting of a scene are used to help the editor cut the scenes together in the order specified in the shooting script. They are also responsible for keeping track of the film production unit's daily progress.
Camera coverage, or coverage, is the amount and kind of footage shot used to capture a scene in filmmaking and video production. The film editor uses coverage in post-production to assemble the final cut.
An eyeline match is a film editing technique associated with the continuity editing system. It is based on the premise that an audience will want to see what the character on-screen is seeing. An eyeline match begins with a character looking at something off-screen, followed by a cut of another object or person: for example, a shot showing a man looking off-screen is followed by a shot of a television. Given the audience's initial interest in the man's gaze, it is generally implied on the basis of the second shot that the man in the first was looking at the television, even though the man is never seen looking at the television within the same shot.
The over-the-shoulder shot is a camera angle used in film and television, where the camera is placed above the back of the shoulder and head of a subject. This shot is most commonly used to present conversational back and forth between two subjects. With the camera placed behind one character, the shot then frames the sequence from the perspective of that character. The over-the-shoulder shot is then utilised in a shot-reverse-shot sequence where both subject's OTS perspectives are edited consecutively to create a back and forth interplay, capturing dialogue and reactions. This inclusion of the back of the shoulder allows audiences to understand the spatial relationships between two subjects, while still being able to capture a closer shot of each subject’s facial expression. In film and television, the filmmaker or cinematographer’s choice of an OTS shot’s camera height, the use of focus and lenses affect the way audiences interpret subjects and their relationships to others and space.
In the post-production process of film editing and video editing, a cut is an abrupt, but usually trivial film transition from one sequence to another. It is synonymous with the term edit, though "edit" can imply any number of transitions or effects. The cut, dissolve, and wipe serve as the three primary transitions. The term refers to the physical action of cutting film or videotape, but also refers to a similar edit performed in software; it has also become associated with the resulting visual "break".

The psychology of film is a sub-field of the psychology of art that studies the characteristics of film and its production in relation to perception, cognition, narrative understanding, and emotion. A growing number of psychological scientists and brain scientists have begun conducting empirical studies that describe the cognitive and biological underpinnings of motion pictures or what has been called "psychocinematics". Early theoretical approaches included works by psychologists Hugo Münsterberg and Rudolf Arnheim. Cognitive film theorists David Bordwell and Noël Carroll fostered its philosophical underpinnings.
