Chroma Key色度键A video key effect in which one video signal is inserted in place of areas of a particular color in another video signal. Blue and green are the chroma key colors most frequently used.一种视频键的效果，即一个视频信号被插入替换到另一个视频信号中，替换的区域是另一信号中的特别的颜色区域。使用得最多最频繁的色键颜色是蓝色和绿色。=========================================Key键An effect where a portion of a background scene is replaced by a new video. Key cut and key fill signals are involved, though in some cases the same signal may be used for both (self key).一种背景场景的一部分被一个新的图像替代的效果。键切割和键填充信号是相关的，在某些情况下这两种信号可以是同一个（自键）。=========================================Key Cut键切割In key effects, the key cut signal is used to specify where to cut a hole in the background that will be filled with the key fill video. The key cut signal determines the shape of the key effect.在键效果中，键切割信号被用来指定将背景图像中哪里抠出一个空洞并被键填充信号填充。键切割信号决定键效果的形状。=========================================Key Fill键填充In key effects, the video signal which fills the hole cut in the background video.在键效果中，在背景图像中填充进切割空洞的视频信号。=========================================Key Invert键翻转Reversing the polarity of a key, such that material formerly keyed out will be keyed in, and vice versa.反转一个键的性质，这样一来素材中先前是键出的将变为键入，反之亦然。=========================================Key Mask键遮罩A key mode which allows use of a wipe pattern generator to prevent some undesirable portions of the key cut signal from cutting holes in the background video.一种键模式，它允许使用划像图案产生器来避免背景图像的切割空洞中某些键切割信号不合需要的部分。=========================================Key Priority键优先权The stacking order of multiple keys. The keyed signal with the highest priority appears in front of all the others. Keyed signals appear below higher priority keys and in front of lower priority keys, in a stack. A key priority transition changes the order of the keys without changing the background output.多种键的层次次序。优先权最高的键控信号在所有其它的键之前出现。在优先权栈中，键控信号在优先权高于它的键之后出现并在优先权低于它的键之前出现。键优先权的改变只改变键的次序而不改变背景图像的输出。=========================================Line
