Animating Effects with Per-Parameter Keyframes in Sony Vegas Pro 11
In this tutorial you'll learn how to make the most of Vegas's new by-parameter keyframing capabilities for effects plug-ins that ship with Vegas Pro 11 using the new Sony 文本 & 以标题插件为例.
In this first installment of our series of tutorials on using the new features in Sony Vegas Pro 11, we're going to talk about an improvement that Sony has made to many of the video plug-in effects included with Vegas Pro, whereby you can now keyframe several individual parameters of those effects.
什么是关键帧?
Before we discuss some of the new elements of keyframing effects in Vegas Pro, I'd like to provide a little background on keyframing for those not familiar with the term. Keyframing is just a way of marking points in events or changes that happen over time to ensure that those changes occur smoothly rather than simply jumping from one state to another.
Douglas Spotted Eagle illustrates this pretty well in 拉斯维加斯专业11编辑车间他的新书《百家乐软件》将于4月出版. He equates keyframes 在视频 to your timeline of the day. 比如，6点钟，你起床. 六点半，你洗澡. 7点钟，你去上班. All these things happen over time, rather than the instants at which you begin and end them.
虽然这在日常生活中似乎是显而易见的, 在视频, you need keyframes to make sure events happen gradually over time, and to exercise optimum control over the parabola of those events.
In this tutorial you'll learn how that translates into Vegas for effects and the changing of parameters for effects, and how to make the most of Vegas's new keyframing capabilities for effects plug-ins that ship with Vegas Pro 11.
在索尼标题中创建标题 & 文本插件
To illustrate the new keyframing-by-parameter capabilities, we're going to use one of the titlers that's in Vegas Pro 11. To begin, right-click on your timeline and select Insert 文本 Media from the menu that appears (图1).
