Tutorial: Creating a 3D Look with 4K Footage in Adobe After Effects CC
在本教程中, we explore how to add depth and visual interest to your videos by applying 3D properties in Adobe After Effects and leveraging the additional pixel real estate in 4K footage used for 1080p HD projects.
在本教程中, I'll show you hot to create a 3D look with 4K footage using Adobe After Effects CC. In the project we'll use as an example, we're creating a video that will be delivered inb 1080p HD. Because the majority of us are creating online videos in 1080p HD (1920x1080), I thought it would be interesting to use the 3840x2160 or 4096x2160 UltraHD/4K footage that many of our cameras are capable of recording, and manipulate it to add 3D-like depth to our videos. 现在, I know that sounds like a lot of numbers, but the idea here is that we're playing with the extra image with which 4K recordings provide us.

Working with the 4K Clip in After Effects
We;ll start with the 4K clip loaded into After Effects. This clip was recorded with the GoPro, and we've already marked the In and Out points we want to use in our footage panel (下面的图2).

To begin, we'll Overlay Edit the clip into the After Effects timeline. The composition on the timeline has been created with 1080 settings. You can change these settings by pressing Command+K (Mac OS) or Ctrl+K (Windows) to open the Composition Settings dialog (下面的图3). 为了达到这个效果, you'll need to select one of the 1080 settings using the Preset pull-down, 然后点击确定.

现在, 当你移动游戏头时, you'll see that the 4K clip is much larger than than the 1080 settings. Drag your footage around in the Composition panel to see how much picture you have to play with.
In order to start manipulating the clip, we need to enable the 3D options for this layer. You can do this by navigating to the Cube icon next to the layer (下面的图4) and selecting it for that clip.

从这里, 在出现的下拉菜单中, we can click the disclosure triangle next to Transform to open the Transform properties and start playing with the values (下面的图5). 我喜欢调整X, Y, and Z Rotation values to the right or left to start getting some unique looks. 很明显, 你可以在这里玩, but how much rotational skew will work will vary based on your specific project and the look you're trying to achieve.
