在电视节目制作中,合成画面是应用非常广泛的技术,与电影中的合成画面制作方法不同。视频合成画面是采用全新的电子技术,将两种或两种以上的视频影像信号合成在一起,形成一个具有一定意义的新的合成影像,这就是我们常说的视频合成画面。视频合成画面的方法有两种:一种是线性视频合成;另一种是非线性视频合成。下面我将对两种合成方法做一下简单说明。一、线性视频合成线性编辑合成方法的特点是只需拨动视频切换系统控制盘上的控制、操作键即可实现,它需要的是一整套视频信号处理设备——视频切换系统,就是平常我们所说的特技机、演播室、视频源(两架以上摄像机)及主控制内的所有视频设备。这种视频合成方法,它可直接在合成过程中通过监视器观察合成后的图
In the production of television programs, the composition of the screen is a very wide range of applications, and the movie in the production of different methods of synthesis. Video synthesis screen is the use of new electronic technology, the two or more video signals together to form a new synthetic image of some significance, which is what we often say that the video synthesis. There are two ways to synthesize video: One is linear video synthesis; the other is nonlinear video synthesis. Below I will make a brief description of the two methods of synthesis. First, the linear video synthesis Linear editing method is characterized by simply dialing the video switching system control panel on the control keys can be achieved, what it needs is a complete set of video signal processing equipment - video switching system is usually us The stunt machines, studios, video sources (two or more cameras) and all video equipment in the main control. This video synthesis method, which can be directly observed in the synthesis process synthesized by the monitor
