Film editors make movies. 

Making a movie is a big job. 

Making a movie takes many steps. One key part is film editing. 
Editors control four main things. First, they look at how shots look. They use light, color, and shapes to connect them. Second, they control the rhythm. Short shots can make a scene feel fast. Long shots can make it feel slow. Third, they manage space. They can show how different places connect. Fourth, they control time. They can use flashbacks to show the past.
Early films were just one long shot. They did not have stories. Later, pioneers like Robert W. Paul used more than one shot. 

Film editing is a special way to make movies. It is a creative and technical job. 
Editors have a lot of control over how a movie feels. They work with four main areas to craft the story. First, they look at graphic relations like light, color, and shapes. Second, they manage the rhythm by changing how long each shot lasts. Short shots can feel fast or even violent. Long shots can let the audience react to an action. Third, they control space to show how different places connect. Finally, they manipulate time using things like flashbacks to show the past.
In the beginning, films were very different. Early movies were just one long, still shot. They did not have stories or any editing at all. People just watched simple things like traffic moving on a street. 
Many filmmakers helped develop the language of movies. James Williamson made films like "Fire!" around 1900. 
Today, editing has changed because of digital technology. In the past, editors mostly worked on the picture. Now, digital systems let editors handle many more things. They might add temporary music or sound effects to a scene. This makes the editor's job much more important than before. They help shape the whole feeling of the film. It is a skill that brings all the parts of a movie together.
Film editing is both a creative and a technical part of the post-production process in filmmaking. It is the art and practice of assembling individual shots into a coherent sequence. An editor works with raw footage to select the highest quality shots. They remove unnecessary frames to ensure every shot is clean. This process transforms separate pieces of film into a finished motion picture. Many people call editing "the invisible art." This is because effective editing can captivate a viewer without them noticing the cuts. 
The role of an editor is much more than just mechanically joining pieces together. They must creatively work with many layers of a production. This includes images, story, dialogue, music, and pacing. They also consider the actors' performances to "re-imagine" or even rewrite the film. This creates a cohesive whole from many different parts. Some famous directors, known as auteurs, even edit their own films. Examples include Akira Kurosawa, Bahram Beyzai, Steven Soderbergh, and the Coen brothers.
According to the book "Film Art, An Introduction," editors control four basic dimensions. The first dimension is graphic relations between shots. Editors analyze the graphic configurations of shot A and shot B. They look at light and dark, lines and shapes, and volumes and depths. They also consider movement and stasis. To manage these relations, they might maintain brightness consistency or keep important elements in the center of the frame. They may also use visual matches to create continuity between shots.
The second dimension is the rhythmic relationship between shots. The duration of each shot is determined by the number of frames or length of film. By adjusting these lengths, a filmmaker controls the overall rhythm. For example, a brief flash of white frames can convey a sudden impact. Conversely, lengthening a shot can allow for an audience reaction. Editors can use shot length to create a steady beat or to change the tempo of a scene.
The third dimension involves the spatial relationship between shots. Editing allows a filmmaker to construct film space and imply connections between different points. They can juxtapose shots to establish spatial holes or build a complete space from component parts. This is called an analytical breakdown. The fourth dimension is the temporal relation between shots. Editing manipulates the time of action in a film. Filmmakers can control the order, duration, and frequency of events. They use techniques like flashbacks and flash-forwards to shape the narrative.
Historically, early films were very different from modern movies. The first films were short, static, and consisted of a single, locked-down shot. There was no story and no editing involved. These films simply showed activity, such as traffic moving along a city street. Each film ran only as long as the film remained in the camera. 
In the late 1890s, filmmakers began experimenting with complex techniques. Georges Méliès used Paul's "Cinematograph Camera No. 1" to create multiple exposures. This allowed him to layer images on top of each other. Around 1900, the Brighton School in England further developed action continuity. George Albert Smith made "As Seen Through a Telescope" in 1900. This film used a cut to a close shot and then a cut back to the original scene.
American filmmaker Edwin S. Porter helped advance these ideas in the early 1900s. He worked for the Edison Company and made "Life of an American Fireman" in 1903. This was the first American film with a plot and a continuous narrative. His most famous work, "The Great Train Robbery" (1903), featured twenty separate shots and ten different locations. 
Modern digital technology has significantly changed the editor's responsibilities. In the past, picture editors dealt only with the visual images. Sound, music, and visual effects editors handled other specific tasks. Today, non-linear digital editing systems have shifted these duties. It is now common for a picture editor to add temporary music or mock up visual effects. They might also add temporary sound effects to help the director. This expanded role makes the editor even more pivotal to a film's success.
