Early experiments




Edwin S. Porter is generally thought to be the American filmmaker who first put film editing to use. Porter worked as an electrician before joining the film laboratory of Thomas Alva Edison in the late 1890s. Early films by Thomas Edison (whose company invented a motion camera and projector) and others were short films that were one long, static, locked-down shot. Motion in the shot was all that was necessary to amuse an audience, so the first films simply showed activity such as traffic moving on a city street. There was no story and no editing. Each film ran as long as there was film in the camera. When Edison's motion picture studio wanted to increase the length of the short films, Edison came to Porter. Porter made the breakthrough film Life of an American Fireman in 1903. The film was among the first that had a plot, action, and even a closeup of a hand pulling a fire alarm.

Other films were to follow. Porter's ground-breaking film, The Great Train Robbery is still shown in film schools today as an example of early editing form. It was produced in 1903 and was one of the first examples of dynamic, action editing (the piecing together scenes shot at different times and places and for emotional impact unavailable in a static long shot). Being one of the first film hyphenates (film director, editor and engineer) Porter also invented and utilized some of the very first (albeit primitive) special effects such as double exposures, miniatures and split-screens.

Porter discovered important aspects of motion picture language: that the screen image does not need to show a complete person from head to toe and that splicing together two shots creates in the viewer's mind a contextual relationship. These were the key discoveries that made all non-live or non live-on-videotape narrative motion pictures and television possible—that shots (in this case whole scenes since each shot is a complete scene) can be photographed at widely different locations over a period of time (hours, days or even months) and combined into a narrative whole. That is, The Great Train Robbery contains scenes shot on sets of a telegraph station, a railroad car interior, and a dance hall, with outdoor scenes at a railroad water tower, on the train itself, at a point along the track, and in the woods. But when the robbers leave the telegraph station interior (set) and emerge at the water tower, the audience believes they went immediately from one to the other. Or that when they climb on the train in one shot and enter the baggage car (a set) in the next, the audience believes they are on the same train.

Sometime around 1918, Russian director Lev Kuleshov did an experiment that proves this point. (See Kuleshov Experiment) He took an old film clip of a head shot of a noted Russian actor and intercut the shot with a shot of a bowl of soup, then with a child playing with a teddy bear, then with a shot an elderly woman in a casket. When he showed the film to people they praised the actor's acting—the hunger in his face when he saw the soup, the delight in the child, and the grief when looking at the dead woman. Of course, the shot of the actor was years before the other shots and he never "saw" any of the items. The simple act of juxtaposing the shots in a sequence made the relationship.

History of film editing technology

The original editing machine: an upright Moviola.

Before the widespread use of non-linear editing systems, the initial editing of all films was done with a positive copy of the film negative called a film workprint (cutting copy in UK) by physically cutting and pasting together pieces of film, using a splicer and threading the film on a machine with a viewer such as a Moviola, or "flatbed" machine such as a K.-E.-M. or Steenbeck. Today, most films are edited digitally (on systems such as Avid or Final Cut Pro) and bypass the film positive workprint altogether. In the past, the use of a film positive (not the original negative) allowed the editor to do as much experimenting as he or she wished, without the risk of damaging the original.

When the film workprint had been cut to a satisfactory state, it was then used to make an edit decision list (EDL). The negative cutter referred to this list while processing the negative, splitting the shots into rolls, which were then contact printed to produce the final film print or answer print. Today, production companies have the option of bypassing negative cutting altogether. With the advent of digital intermediate ("DI"), the physical negative does not necessarily need to be physically cut and hot spliced together; rather the negative is optically scanned into computer(s) and a cut list is conformed by a DI editor.

There are several editing stages and the editor's cut is the first. An editor's cut (sometimes referred to as the "Assembly edit" or "Rough cut") is normally the first pass of what the final film will be when it reaches picture lock. The film editor usually starts working while principal photography starts. Likely, prior to cutting, the editor and director will have seen and/or discussed "dailies" (raw footage shot each day) as shooting progresses. Screening dailies gives the editor a ballpark idea of the director's intentions. Because it is the first pass, the editor's cut might be longer than the final film. The editor continues to refine the cut while shooting continues, and often the entire editing process goes on for many months and sometimes more than a year, depending on the film.

Director's cut

When shooting is finished, the director can then turn his full attention to collaborating with the editor and further refining the cut of the film. This is the time that is set aside where the film editor's first cut is molded to fit the director's vision. In the United States, under DGA rules, directors receive a minimum of ten weeks after completion of principal photography to prepare their first cut.

While collaborating on what is referred to as the "director's cut", the director and the editor go over the entire movie with a fine-tooth comb; scenes and shots are re-ordered, removed, shortened and otherwise tweaked. Often it is discovered that there are plot holes, missing shots or even missing segments which might require that new scenes be filmed. Because of this time working closely and collaborating – a period that is normally far longer, and far more intimately involved, than the entire production and filming – most directors and editors form a unique artistic bond.

Final cut
Main article: Final cut privilege
Often after the director has had his chance to oversee a cut, the subsequent cuts are supervised by one or more producers, who represent the production company and/or movie studio. There have been several conflicts in the past between the director and the studio, sometimes leading to the use of the "Alan Smithee" credit signifying when a director no longer wants to be associated with the final release.

Emotional versus Physical continuity
Continuity is a film term that suggest that a series of shots should be physically continuous, as if the camera simply changed angles in the course of a single event. For instance, if in one shot a beer glass is empty, it should not be full in the next shot. Live coverage of a sporting event would be an example of footage that is very continuous. Since the live operators are cutting from one live feed to another, the physical action of the shots matches very closely. Many people regard inconsistencies in continuity as mistakes, and often the editor is blamed. In film, however, continuity is very nearly last on a film editor's list of important things to maintain.

Technically, continuity is the responsibility of the script supervisor and film director, who are together responsible for preserving continuity and preventing errors from take to take and shot to shot. The script supervisor, who sits next to the director during shooting, keeps the physical continuity of the edit in mind as shots are set up. He is the editor's watchman. If shots are taken out of sequence, as is often the case, he will be alert to make sure that beer glass is in the appropriate state. The editor utilizes the script supervisor's notes during post-production to log and keep track of the vast amounts of footage and takes that a director might shoot.

Editors can choose between emotional and storytelling aspects of any given film over continuity- something that is much more abstract and harder to judge. (Which is why films often take much longer to edit than to shoot.) Emotional continuity, and the clarity of storytelling, can take precedence over "technicalities". In fact, very often something that is physically discontinuous will be completely unnoticeable if the emotional rhythm of the scene "feels" right. If you were to slow down scenes from many of your favorite movies, you could easily find many minuscule physical differences from one cut to the next, which are completely hidden by the course of the emotional events.

However, if a continuity error is glaring enough (as in the case of the beer glass), and the edit is emotionally necessary, it is increasingly common to order a visual effect to fix the problem. Such an effect is not "cheating" or unnecessary: as a rule, anything that distracts from the storytelling is worthy of elimination.

A good example of a continuity error is in the film Braveheart with Mel Gibson. In one of the battle scenes you see William Wallace (Mel Gibson) and his army of Scottish rebels charging into battle with the English. At one moment, you see him with no weapon. Then you see him with his claymore in hand. Then again he has no weapon. Then a pick axe. And when he finally closes in on the enemy, you see him draw his claymore from his back. This often goes unnoticed by audiences and it does not cause any real problems. The whole idea of the scene is to show the rebels fiercely charging into battle, and these errors do not actually interfere with that.

Methods of montage

In motion picture terminology, a montage (from the French for "putting together" or "assembly") is a film editing technique.

There are at least three senses of the term:

  • In French film practice, "montage" has its literal French meaning (assembly, installation) and simply identifies editing.

  • In Soviet filmmaking of the 1920s, "montage" was a method of juxtaposing shots to derive new meaning that did not exist in either shot alone.

  • In classical Hollywood cinema, a "montage sequence" is a short segment in a film in which narrative information is presented in a condensed fashion.


Soviet montage

Lev Kuleshov was among the very first to theorize about the relatively young medium of the cinema in the 1920s. For him, the unique essence of the cinema — that which could be duplicated in no other medium — is editing. He argues that editing a film is like constructing a building. Brick-by-brick (shot-by-shot) the building (film) is erected. His often-cited Kuleshov Experiment established that montage can lead the viewer to reach certain conclusions about the action in a film. Montage works because viewers infer meaning based on context.

Although, strictly speaking, U.S. film director D.W. Griffith was not part of the montage school, he was one of the early proponents of the power of editing — mastering cross-cutting to show parallel action in different locations, and codifying film grammar in other ways as well. Griffith's work in the teens was highly regarded by Kuleshov and other Soviet filmmakers and greatly influenced their understanding of editing.

Sergei Eisenstein was briefly a student of Kuleshov's, but the two parted ways because they had different ideas of montage. Eisenstein regarded montage as a dialectical means of creating meaning. By contrasting unrelated shots he tried to provoke associations in the viewer, which were induced by shocks.

Montage sequence

Main article: Montage sequence
A montage sequence consists of a series of short shots that are edited into a sequence to condense narrative. It is usually used to advance the story as a whole (often to suggest the passage of time), rather than to create symbolic meaning. In many cases, a song plays in the background to enhance the mood or reinforce the message being conveyed. One famous example of montage was seen in the 1968 film 2001: A Space Odyssey, depicting the start of man's first development from apes to humans

Continuity editing

What became known as the popular 'classical Hollywood' style of editing was developed by early European and American directors, in particular D.W. Griffith in his films such as The Birth of a Nation and Intolerance. The classical style ensures temporal and spatial continuity as a way of advancing narrative, using such techniques as the 180 degree rule, Establishing shot, and Shot reverse shot.

Alternatives to continuity editing (non-traditional or experimental)

Early Russian filmmakers such as Lev Kuleshov further explored and theorized about editing and its ideological nature. Sergei Eisenstein developed a system of editing that was unconcerned with the rules of the continuity system of classical Hollywood that he called Intellectual montage.

Alternatives to traditional editing were also the folly of early surrealist and dada filmmakers such as Luis Buñuel (director of the 1929 Un Chien Andalou) and René Clair (director of 1924's Entr'acte which starred famous dada artists Marcel Duchamp and Man Ray). Both filmmakers, Clair and Buñuel, experimented with editing techniques long before what is referred to as "MTV style" editing.

The French New Wave filmmakers such as Jean Luc Godard and François Truffaut and their American counterparts such as Andy Warhol and John Cassavetes also pushed the limits of editing technique during the late 1950s and throughout the 1960s. French New Wave films and the non-narrative films of the 1960s used a carefree editing style and did not conform to the traditional editing etiquette of Hollywood films. Like its dada and surrealist predecessors, French New Wave editing often drew attention to itself by its lack of continuity, its demystifying self-reflexive nature (reminding the audience that they were watching a film), and by the overt use of jump cuts or the insertion of material not often related to any narrative.

Editing techniques

Vsevolod Pudovkin noted that the editing process is the one phase of production that is truly unique to motion pictures. Every other aspect of film making originated in a different medium than film (photography, art direction, writing, sound recording), but editing is the one process that is unique to film. Kubrick was quoted as saying: "I love editing. I think I like it more than any other phase of film making. If I wanted to be frivolous, I might say that everything that precedes editing is merely a way of producing film to edit."
Edward Dmytryk stipulates seven "rules of cutting" that a good editor should follow:
"Rule 1: Never make a cut without a positive reason."
"Rule 2: When undecided about the exact frame to cut on, cut long rather than short."
"Rule 3: Whenever possible cut 'in movement'."
"Rule 4: The 'fresh' is preferable to the 'stale'."
"Rule 5: All scenes should begin and end with continuing action."
"Rule 6: Cut for proper values rather than proper 'matches'."
"Rule 7: Substance first—then form."

According to Walter Murch, when it comes to film editing, there are six main criteria for evaluating a cut or deciding where to cut. They are (in order of importance, most important first, with notional percentage values.):

Emotion (51%) — Does the cut reflect what the editor believes the audience should be feeling at that moment?
Story (23%) — Does the cut advance the story?
Rhythm (10%) — Does the cut occur "at a moment that is rhythmically interesting and 'right'" (Murch, 18)?
Eye-trace (7%) — Does the cut pay respect to "the location and movement of the audience's focus of interest within the frame" (Murch, 18)?
Two-dimensional plane of the screen (5%) — Does the cut respect the 180 degree rule?
Three-dimensional space of action (4%) — Is the cut true to the physical/spatial relationships within the diegesis?

Murch assigned the notional percentage values to each of the criteria. "Emotion, at the top of the list, is the thing that you should try to preserve at all costs. If you find you have to sacrifice certain of those six things to make a cut, sacrifice your way up, item by item, from the bottom."-Murch
