With the continuous development of digital technology and its wide application in various industries, in the mid-1990s, non-linear editing appeared around us and developed rapidly. The so-called non-linear editing is to video clips in accordance with the order and length of the original, free to arrange, edit the way, after the completion of the program can be arbitrarily change the length of one of the paragraphs or insert delete other paragraphs. Compared with linear editing, non-linear editing is more convenient and efficient. As digital technology becomes more and more mature and information storage capacity can be expanded almost infinitely, non-linear editing applications in broadcasting, film, and TV program production will become more and more extensive.
From the perspective of the non-linear editing system , it can integrate video recorders, digital aerobatic machines, editing machines, multitrack recorders, mixers, MIDI creations, time bases and other devices, covering almost all the traditional post-production equipment. This highly integrated feature makes the advantages of nonlinear editing systems even more pronounced. It is therefore not surprising that it can take an increasingly important position in the broadcast and television industry. In a nutshell, nonlinear editing systems have the advantages of high signal quality, high level of production, investment saving, investment protection, and networking.
High signal quality
With traditional video tape editing programs, the material tape wears many times and mechanical wear is irreparable. In addition, in order to make special effects, it must also be “replicatedâ€. Every time it is “replicatedâ€, it will result in a signal loss. In the end, for quality considerations, often have to reluctantly cut off love, give up some good artistic ideas and processing methods. In a non-linear editing system, these defects do not exist, and the signal quality will be consistent regardless of how it is handled or edited and copied. Of course, because of the compression and decompression coding of the signal, there is some quality loss, but the loss is greatly reduced compared to “copyingâ€. In general, the loss of quality of the acquired signal is less than half of the loss of transcription. Since the system requires only one acquisition and one output, the non-linear editing system can guarantee a program band equivalent to the quality of the second version. However, using a conventional linear editing system, such high signal quality can never be achieved.
High production level
Using traditional editing methods, to create a program for a period of ten minutes, it often takes up to forty-five minutes of material, repeatedly review and compare, and then select the editing group of the lens and make the necessary transitions. , special effects processing. This includes a lot of mechanical duplication. In the non-linear editing system, a large amount of material is stored on the hard disk, which can be called at any time, and does not require time-consuming and laborious frame-by-frame search. The search for material is extremely easy, without having to rewind back and forth like a traditional editor. Dragging a slider with the mouse can instantly find the frame you need. Searching and writing are easy. The entire editing process is just like word processing, which is both flexible and convenient. At the same time, a wide variety of tricks, refurbished, and freely combinable special effects methods make the programs produced rich and colorful, raising the level of production to a new level.
long life
The high integration of the non-linear editing system with traditional equipment minimizes the equipment required for post-production and effectively saves investment. And because it is a non-linear editing, only one video recorder is needed. During the entire editing process, the video recorder only needs to be started twice, once to input material, and once to record the program tape. This avoids a lot of wear on the drum, which greatly extends the life of the video recorder.
Easy to upgrade
The improvement of the level of film and television production has always put forward new requirements for the equipment. This contradiction is difficult to solve in the traditional editing system because it requires continuous investment. Using a non-linear editing system can better solve this contradiction. The non-linear editing system adopts an open structure that is easy to upgrade and supports many third-party hardware and software. Usually, the increase in functionality only needs to be achieved through software upgrades.
Networking
Networking is a major development trend of computers. Non-linear editing systems can make full use of the network to easily transmit digital video, achieve resource sharing, and can also use computers on the network for collaborative creation. For the management and query of digital video resources, it is very easy. . In some television stations, non-linear editing systems are using the Internet to play a greater role.
