20.2 视频效果

Example 1 (Continued)
示例1(续)
9. Click on the FX button for the video track Zebras. When the Add FX window is displayed, make sure that All Plugins is selected in the left pane. In the right pane click on Video processor then OK. Instead of a window with a standard familiar plug-in interface you will see something quite different. Currently no effect has yet been loaded.
9.点击视频轨道Zebras的FX按钮。当显示添加FX窗口时,确保在左窗格中选中了“全部插件”。在右窗格中,单击“Video processor(视频处理器)”,然后单击确定。您看到的不是一个标准的熟悉插件界面的窗口,而是完全不同的东西。目前还没有加载任何效果。
10. Let's add a title. From the presets drop down list choose Overlay: Text. This might look a bit strange (see right).
10.让我们添加一个标题。从预置下拉列表中选择“叠加: 文本”。这看起来可能有点奇怪(见右图)。
11. The first black column displays the parameter controls. These determine the size, appearance and position of the text.
11.第一个黑色列显示参数控件。它们决定了文本的大小、外观和位置。
12. The second column contains the actual EEL code used to create the effect. Notice that your video window currently displays the message #text="". Y Click in this pane and edit this line to read Text=”Zebras”; (edit only the text between the quote marks, nothing else), then press Ctrl S to save. The text in your video window changes.
12.第二列包含用于创建效果的实际EEL代码。请注意,视频窗口当前显示的消息是: #text=""。在此窗格中单击Y,并编辑此行,以显示text="Zebras";(仅编辑引号之间的文本,不编辑其他内容),然后按Ctrl+S保存。视频窗口中的文本会更改。
13. Lets create some effects. Click first on this FX's text height parameter control button, then on the Param button (top right), then Show track envelope. Add points and adjust this envelope as shown here.
13.让我们创造一些效果。首先单击此FX的文本高度参数控制按钮,然后单击“参数按钮”--“显示轨道包络”。添加点并调整此包络,如下所示。
14. With your mouse adjust the y position knob to approx 0.07. Play the video. The text will now appear higher up, starting very small and growing larger. Setting text bright to 0 will make the text more clearly visible
14.用鼠标将y的位置旋钮调整到大约0.07。播放视频。文本现在将显示在更高的位置,开始时非常小,然后逐渐变大。将文本亮度设置为0,会使文本更清晰可见
15. Let's suppose we only want to display the title for 10 seconds or so. This can be achieved by adding a bypass envelope. Click on the automation button for the Zebras video track (labelled “trim”). Under the heading text overlay select Bypass. Close the window: a bypass envelope will be displayed just beneath the track.
15.假设我们只想标题显示10秒左右。这可以通过添加旁通包络来实现。点击Zebras视频轨道(标记为“修剪”)的自动化按钮。在标题“文本叠加”下,选择“旁通”。关闭窗口:旁通包络将显示在轨道正下方。
16. At or around the 10 second mark, add a point to this envelope and drag that point up, as shown below:
16.在10秒标记处或附近,在此包络中添加一个点,并向上拖动该点,如下图所示:
17. Save the file and play the video.
17.保存文件并播放视频。
18. Now let's add a visual effect. In the FX chain for the Zebras video track, add a second instance of the video processor.
18.现在让我们添加一个视觉效果。在Zebras视频轨道的FX链中,添加视频处理器的第二个实例。
19. Into this effect load the preset Transition: horizontal wipe. This preset includes the parameter control, labelled wipe pos.
19.在这个效果中加载预置的“过渡: 水平擦拭”。此预置包括参数控件,标记为“擦拭位置”。
20. Save the file and play it. Notice you can now only see half of the picture in the video window: the other half is blackened out!
20.保存文件并播放。请注意,您现在只能在视频窗口中看到图片的一半:另一半已经变黑了!
21. We can fix this with an automation envelope. Add and envelope for this track for the parameter wipe pos on the horizontal wipe effect.
21.。我们可以用自动化包络来解决这个问题。为该轨道添加一个水平擦拭效果中的“擦拭位置”参数包络。
22. Adjust this envelope as shown below: you do not need to be exact in positioning the points.
22.。如下所示调整此包络线: 您不需要精确定位这些点。
23. Save the file and play the video. The picture will now scroll out from the right at the end of the video.
23.保存文件并播放视频。图片现在将从视频末尾的右侧滚动。
In the next example we will be a little more ambitious with our use of effects.
在下一个示例中,我们将在使用效果方面更加雄心勃勃。
Note 1: When you modify and the code of a video effect, you are only changing it for that single instance, you are not changing the default. If you make a mistake or get confused, simply remove the plug-in from the FX chain, reinsert it and start again.
注1: 当您修改视频效果的代码时,您只更改了该单个实例的代码,而不是更改默认设置。如果您犯了错误或感到困惑,只需将插件从FX链中移除,重新插入,然后重新启动即可。
Note 2: Pressing F1 from within a preset code window will open a help window which includes a list of parameters used by that preset,.
注2: 在预置代码窗口中按F1将打开一个帮助窗口,其中包含该预置使用的参数列表。
