新闻演播中的背景是至关重量的,形成的方法通常有二种。一种是采用抠像将所需的画面衬托在播音员后面,这种方法可快速地更换背景,演播区要求低,其缺点是人物与背景间缺少协调统一的立体感。另一种就是构造一个实际的新闻背景,从而克服了抠像的不足,但也产生了另一个缺点,即对演播区的要求高,资金投入大,不易更换。怎样才能将上述两种方法的优点结合在一起呢?
The background in a news studio is of the utmost importance, and there are usually two types of methods. One is the use of keying to bring the desired picture behind the announcer, this method can quickly change the background, studio area requirements are low, the disadvantage is the lack of coordinated character and background between the three-dimensional sense. The other is to construct a real news background, thus overcoming the lack of keying, but also has another drawback, that is, the requirements of the studio high, capital investment, difficult to change. How can we combine the advantages of these two methods?
