近年来,随着计算机技术和影视数字化技术的飞速发展,非线性编辑技术也得到了快速发展和普及。由于非线性编辑系统的设备占用空间小,系统功能集成度高,优越的编辑随意性和无多版复制问题,因而在片头制作、栏目包装、节目编辑等电视节目制作领域已有广泛的应用。然而,非线性编辑系统虽然提供了编辑的方便性、随意性和瞬时性,大大缩短了编辑的时间,但是它也增加了另外一些与节目本身无关的工作量,例如,把大量素材录入硬盘、制作完成后的节目输出、特技效果的生成、各种数据的清除与整理等等。因此,通常它的实际制作效率并没有许多厂商所宣传的那么理想。1995 In recent years, with the rapid development of computer technology and digital video technology, nonlinear editing technology has also been rapidly developed and popularized. Nonlinear editing systems have been widely used in the field of film production, program packaging, program editing and other television program production due to their small device footprint, high system integration, superior editing freedom and no multi-copy problems. However, the non-linear editing system has greatly reduced the editing time by providing convenience, arbitrariness and instantaneity of editing, but it also adds other workloads unrelated to the program itself, for example, recording a large amount of material on the hard disk, After the completion of the production program output, the generation of special effects, a variety of data removal and finishing and so on. Therefore, usually its actual production efficiency is not as ideal as many manufacturers have advertised. 1995
