视频编辑器Adobe Premiere Pro CC(Adobe Premiere Pro CC)中有许多可用的效果，可以帮助您制作有趣的视频。缩放效果是一种效果，可以帮助您强调视频的某些部分或创建过渡。(create a transition)这创造了独特的视觉效果。
要完成放大效果，您需要知道如何缩小，以便返回到剪辑的原始视图。这就像放大一样简单，所以一旦您知道如何操作，您也将很快能够学会缩小。
在本文中，我们将教您如何执行这两项操作，以及如何在您自己的视频中使用这些放大和缩小效果。
如何制作放大效果
在开始本教程时，我们假设您已打开项目，并且要应用放大效果的剪辑已放置在时间轴中。从此时起，您可以按照以下步骤来创建效果。
- 单击(Click)要具有放大效果的剪辑。
- 前往效果控件(Effect Controls)面板并打开运动选项。
- 要放大剪辑的特定区域，请在“程序”面板中找到称为(Program)“锚点”(Anchor Point)的圆形蓝色目标，当您在面板中选择它时，该目标可能位于剪辑的中间。
- 使用鼠标单击锚点(Anchor Point)并将其拖动到剪辑中要放大的点。
- 现在，通过更改数值或使用滑块来使用缩放效果。(Scale)增加数字将导致锚点(Anchor Point)放大。
在播放过程中，您可能会注意到视频剪辑一播放就会出现放大效果。如果您想让放大效果在剪辑播放时更慢地发生，则需要利用关键帧来实现。如果您还不熟悉关键帧，请先查看我们有关该主题的文章(our article on the topic)。然后，按照以下步骤创建逐渐放大。
- 首先，将锚点(Anchor Point)放置在剪辑上要放大的区域。
- 单击(Click)“效果控件”(Effect Controls)面板中“锚点”(Anchor Point)旁边的秒表图标。
- 现在，将其设置为您想要放大起点的位置后，
单击“缩放”效果旁边的秒表图标。(Scale)
- 在效果控件旁边显示的关键帧时间轴中，将播放头（时间轴中的蓝色标记）滑动到剪辑中要结束放大的点。
- 使用缩放(Scale)效果并设置值，使其完全放大到您想要的点。更改“比例”(Scale)值后，将自动设置关键帧。
请记住，两个“缩放”(Scale) 关键帧(keyframes)距离越近，放大效果发生的速度就越快。因此，您可以通过将关键帧(keyframes)移近或移远来调整速度。这应该会产生平滑的放大效果。
如何缩小
如果您已经放大并想要缩小，则过程相对简单。放大和缩小都需要使用关键帧，因此如果您按照上述步骤实现了放大，则可以使用后续步骤来缩小。
- 从放大点的关键帧开始，将关键帧时间轴中的播放头移动到您希望剪辑完全缩小的点。
- 使用缩放(Scale)效果并将其滑回到放大之前的原始值。
- 将自动设置缩小的关键帧。您可以沿着关键帧时间轴滑动它来改变速度。
以原始比例缩小剪辑只会使剪辑后面的背景可见。如果您希望剪辑以缩小开始，则必须首先放大剪辑开头的比例，然后使用关键帧从那里创建缩小。
如何放大一个剪辑中的
多个点(Multiple Point)
也许您不仅需要一个剪辑中的一种放大效果，还需要两种放大效果。这是完全可能的，但您必须从一开始就使用Position效果而不是Anchor Point创建放大效果。按照以下步骤在一个剪辑中创建多个放大点。
- 将注意力转向位置(Position)效果并打开秒表，打开关键帧时间线。同时打开Scale的秒表，确保其处于原始值。
- 使用“位置”(Position)控件或双击“程序”(Program)面板中的剪辑，然后将剪辑的位置拖动到新的放大点。
- 将关键帧播放头移动到剪辑中您想要第二次放大的位置。
- 像以前一样使用缩放(Scale)效果来创建下一个带有关键帧的放大效果。
按照上述方法，您可以在一个剪辑中获得任意数量的放大效果。

How to Make a Zoom In or Out Effect in Adobe Premiere
There аre many effectѕ available in the video editor Adobe Premiere Pro CC which can help you make interesting videoѕ. Оne effect, which can help you emphasize certain parts of your video or create a transition, is a zoom effect. This creates a unique visual effect.
To complete the zoom in effect, you will need to know how to zoom out so you can get back to the original view of your clip. It’s just as easy as doing a zoom in, so once you know how to do that you’ll quickly be able to pick up zooming out too.
In this article we’ll teach you how to do both, and how to use these zoom in and out effects in your own videos.
How to Make a Zoom In Effect
To begin this tutorial, we’ll assume that you already have your project open and the clip you want to apply the zoom in effect to is placed in your timeline. From this point on, you can follow the steps below to create the effect.
- Click on the clip which you want to have a zoom-in effect.
- Head to the Effect Controls panel and open the Motion options.
- To zoom in to a particular area of your clip, in the Program panel locate the circular blue target, called the Anchor Point, likely in the middle of your clip when you select it in the panel.
- Using your mouse, click and drag the Anchor Point to the point in your clip you want to zoom in to.
- Now, use the Scale effect by either changing the numerical value or using the slider. Increasing the number will produce a zoom-in on the Anchor Point.
During playback, you may notice the zoom in effect happens as soon as the video clip plays. If you want to have the zoom-in effect take place more slowly, as the clip plays, you’ll need to utilize key frames to do so. If you’re not acquainted with key frames yet, check out our article on the topic first. Then, follow these steps to create a gradual zoom in.
- First, place the Anchor Point on the area you want to zoom in to on your clip.
- Click on the stopwatch icon next to Anchor Point in the Effect Controls panel.
- Now, click on the stopwatch icon next to the Scale effect, after setting it to where you want your zoom in starting point to be.
- In the keyframe timeline that appears next to your effect controls, slide the playhead (the blue marker in the timeline) to the point in your clip where you want the zoom in to end.
- Use the Scale effect and set the value so it’s fully zoomed in to the point you want. A keyframe will automatically be set once you change the Scale value.
Keep in mind that the closer together your two Scale keyframes are, the faster the zoom in effect will take place. So, you can adjust the speed by moving the keyframes closer or further apart. This should produce a smooth zoom in effect.
How to Zoom Out
If you’ve already zoomed in and want to zoom back out, the process is relatively simple. Zooming both in and out requires using keyframes, so if you followed the steps above to achieve a zoom in, you can use these next steps to zoom back out.
- From the keyframe of your zoom in point, move your playhead in the keyframe timeline to the point you want your clip to be fully zoomed out.
- Use the Scale effect and slide it back to the original value, before the zoom in.
- The keyframe for the zoom out will automatically be set. You can slide it along the keyframe timeline to alter the speed.
A zoom out of a clip already at its original scale will only make the background behind the clip visible. If you want your clip to begin with a zoom out, you’ll have to first enlarge the scale at the beginning of the clip and use keyframes to create a zoom out from there.
How to Zoom In to Multiple Point In One Clip
Maybe you want not only one, but two zoom in effects within one clip. This is entirely possible, but you’ll have to create your zoom in effects from the beginning with the Position effect instead of the Anchor Point. Follow these steps to create multiple zoom in points within one clip.
- Turn your attention to the Position effect and turn on its stopwatch, opening the keyframe timeline. Also turn on the stopwatch for Scale, making sure it’s at its original value.
- Use the Position controls or double-click on your clip in the Program panel and drag the position of your clip to your new zoom in point.
- Move your keyframe playhead to the point in the clip where you want a second zoom in.
- Use the Scale effect the same as before to create your next zoom in with keyframes.
You could potentially have as many zoom in effects as you want in one clip by following the method above.
Create Visual Interesting Videos With a Zoom In or Out
A zoom in can have many useful or stylistic purposes within a video, and knowing how to create one is important beginner knowledge to have when it comes to video editing. Thankfully, it’s not too difficult to do this in Adobe Premiere Pro, especially if you have some knowledge already in using effects and editing keyframes.
