What is the specific purpose of film and television editing? Thank you.

The entire work of decomposing and reorganizing film audio and video materials. Cut-ting refers to the specific process of film processing. Montage refers to both the artistic skills of lens assembly and the artistic effects obtained by editing. In some countries, it is synonymous with "editing". Editing is the selection, selection and assembly of a large amount of material shot in a film, and finally compiles it into a work that is coherent, smooth, clear and artistically appealing. It is an important part of film art creation and indispensable for film production. It is an important process and a re-creation of a film from shooting to completion. In the early stages of filmmaking, the stage play was simply captured on film intact, which was actually a moving photo of the stage play. At the beginning of the 20th century, starting from the American film director D.W. Griffith, the split-shot shooting method was used to break down the content into different shots and shoot them separately. For example, using close-ups, close-ups and other shots to highlight details, and using panoramic and long shots To introduce the environment, use a series of short shots to create atmosphere and rhythm through rapid transitions, thus making the film break away from the frame of stage drama, event photography, and become an independent modern art, which also gave rise to the art of editing. Editing is originally part of the director's job, and it is a very important part. With the continuous development of science and technology, movies have evolved from early silent films to sound films. The editing process has become more and more complex. In addition, with the continuous updating of film expression techniques, the director's creative tasks have become more and more arduous. He can no longer Now that I have time to operate editing equipment and edit videos myself, editing professionals have gradually emerged: editors and editing assistants. Editors, like photographers, artists, and sound engineers, are close collaborators of the director. Starting from the preparatory stage of the film crew, he participated in all creative activities related to the director, such as discussing the shot script, rehearsing the scene (that is, the shot rehearsal before shooting), etc. He must fully understand the concepts and assumptions of the editor, director, and actor, and then edit the film according to the scene and shot scripts provided by the director and the more specific plan during shooting. Storyboarding (director design) and montage (shot editing) are two aspects of the same thing. The former is intention and the latter is implementation. Therefore, some people also call editing "the post-production work of splitting shots." But "late period" does not mean simple craft operations, it is a stage rich in creative labor. Whether the lens assembly is appropriate directly affects the integrity and appeal of the screen image, and determines the quality of the completed film. The degree of reliance on editing varies depending on the working habits of different directors. However, in addition to fully reflecting the director's creative intentions, the editor can also propose new editing ideas based on the director's shot-by-shot script, suggesting that the director add certain shots or Deleting certain shots, re-adjusting and supplementing the original shot design to make the context of a certain paragraph or plot of the film clearer, the meaning clearer, and the rhythm more distinct.
