This tutorial will demonstrate an advanced method of adding a slider or jib effect to timelapse footage in Adobe After Effects CC 2014.
在本教程中, I’ll show you how to create a moving time-lapse effect using Adobe After Effects Creative Cloud 2014. In 另一个最近的教程, I showed you how to add a slider or jib effect to your timelapses by using Adobe Premiere with 2K footage in a 1080 sequence. 一定要去看看 这个教程 一个简单的方法来实现这个外观.
This tutorial is going to show you a more advanced method of that technique with a use of a few extra features in Adobe After Effects.
开始在After Effects
我们将开始导入剪辑到Adobe After Effects. 我们将创建一个新的合成，并选择1080的预设(下面的图1). 接下来，我们将添加一个2K甚至4K剪辑到时间轴.
图1. 在合成设置对话框中选择1920x1080像素
You can turn the audio off for this clip by selecting the speaker button to the left of your clip (下面的图2)，因为我们并不关心这个项目的音频.
图2. 点击这里关闭剪辑的音频.
The first step we'll take is to adjust the duration of our clip from just under 8 minutes down to 10 seconds. You can do this by right-clicking in the Duration area and scrolling down to Columns (下面的图3). Here, you want to make sure that the check mark next to duration is enabled.
图3. 点击这里打开时间拉伸对话框.
Now, we can alter the duration of this clip and have After Effects do the math for us. 我们知道我们需要一个10秒的剪辑长度, so let's enter that as the new duration in the Time Stretch dialog (下面的图4). 按OK. Now After Effects has adjusted the length of our clip to fit the 10-second duration. Do a RAM preview to see what clip looks like sped up from 7 minutes, 58 seconds to 10 seconds.
