One of the last stages of filmmaking is done in the post-production of the film, during which the selection and linking of the scenes in the raw film (footage) and turning them into sequences is used to reach the final film. In the world of film, “editing” plays the same role as the mind in reality; That is, it reveals what is hidden, and what is obvious, but does not need to be seen, is hidden; It means choosing the best image to see. This step includes selecting the views and their size, arranging the views, scenes and sequences in a row, mixing all the sounds and determining their volume, and finally merging and synchronizing the final sound with the image. This is done through the use of decoupage script, the rules and principles of filmmaking, and the artistic taste and creativity of the editor. Although this stage is also called assembly and editing, it is the artistic aspect of this stage, and assembly and editing mostly means using tools.

By compiling, a narration can be told continuously and fluently. Compilation compresses time and place, emphasizes and juxtaposes different and scattered elements, and arranges them so as to create specific semantic patterns. Editing also shapes the reaction of the audience. For example, presenting a series of short scenes that intersect quickly can create a sense of excitement, adventure and anticipation in the viewer, while long scenes are relaxing, emphasize the dramatic element of the scene and make the viewer more familiar with the characters in the film. They get involved. The combination of sound and image also has a very important effect on the viewer. For example, whether the conversations are audible or not, presenting music at certain moments of the film, increasing and decreasing the volume of the sounds, hearing the ambient sound, etc., all create a special meaning and direct the viewer’s emotions in one direction.

Editing usually begins at the same time as filming, in which the editor takes over the films that are taken each day (Rush) and, in consultation with the director, puts them together. When the filming is over, the filmmaker is in control of the film, which, in a crude and subtle way, follows only the course of events of the film. The editor starts editing with this film. With the director’s opinion, he selects the best shots and compares the sound pattern of the film with the image. This version of the film, which is the first version of the film to reach its final form, is called the Rough Cut. Of course, this version is also called the filmmaker’s edited version, because it more or less contains the filmmaker’s view of the film and has not yet been much interfered with by anyone else.
