What is the difference between post-production of film and television and digital film and television?

Generally speaking, film and television post-production includes three aspects: first, the combination of shots, which is usually called editing; Second, the production of special effects. For example, the special transition effect of the lens, fade in and out, circle in and out. Now it also includes the use of animation and 3D special effects. Thirdly, after the appearance of sound and stereo sound enter the film, we should also consider a problem of post-sound production, including vertical montage in film theory. These three points are indispensable parts of film and television post-production.

Computer-based digital nonlinear editing technology has greatly developed editing means. This technology records materials into a computer and uses the computer to edit them. It adopts the nonlinear mode of film editing, but it uses simple mouse and keyboard operation instead of manual operation, and the editing results can be played back immediately, so the efficiency is greatly improved. At the same time, it can not only provide all the special effects of various editors, but also provide complex special effects that editors can't do through the expansion of software and hardware. Digital nonlinear editing not only combines the advantages of traditional film editing, but also develops further, which is a great progress in film editing technology. Since 1980s, digital nonlinear editing has gradually replaced the traditional methods in foreign film production and become the standard method of film editing. In China, the use of digital nonlinear editing for film editing is still a matter of recent years, but it has developed very rapidly. At present, most directors have realized its advantages.

Composition software: AE, Combustion, DFsion, Shake, premiere, etc. , the two are different from each other, that is, hierarchical and nodal composition software (the former two are hierarchical and the latter two are nodal).

Three-dimensional software: 3D MAX, MAYA, Softimage, Zbrush, etc.

It is not easy for vocational high schools to learn these courses well.
