播放您录制的视频只是为了发现其中一些视频有可怕的相机抖动？有时，无论您的手艺有多好，您的视频都会出现一些不合时宜的情况。这会使您的视频看起来不那么专业、分散注意力或模糊您的主题——所有这些都是您想要避免的。
视频编辑软件Adobe Premiere Pro的创建者预见到了这种情况，并慷慨地提供了一种在后期制作中稳定抖动镜头的方法。它非常适用于最小到中等的抖动，并且可以真正使您的最终作品看起来更加抛光。在本Premiere Pro教程中，我们将向您展示如何在视频编辑过程中应用和使用这种稳定效果。
如何稳定抖动的视频(How to Stabilize Shaky Video)
在开始之前，您需要确保将要使用的视频剪辑导入Premiere。转到媒体浏览器(Media Browser)。在您的计算机上搜索您正在使用的视频文件。选择(Select)文件并将其拖到您的时间轴中。它们也将自动导入到项目文件中。
现在您已导入剪辑并在时间轴中，您可以开始使用Premiere中的(Premiere)Warp Stabilizer来稳定它们。请按照(Follow)以下步骤执行此操作。
- 确定(Decide)需要稳定的剪辑并选择它。
- 转到“效果(Effects)”面板，然后转到“Video Effects > Distort > Warp Stabilizer器” 。
- 单击(Click)并将其拖动到剪辑上，效果将被应用。
Premiere将需要几秒钟来分析视频，然后为您稳定它。然后，您可以在“预览(Preview)”面板中播放它，看看您是否喜欢结果。如果出现问题，您可以通过多种方式在“效果控件(Effect Controls)”面板中编辑此效果，使其看起来完全符合您的要求。
如何编辑稳定效果(How to Edit the Stabilization Effect)
如果您想更改稳定效果的任何内容，例如移动、稳定方法、边框、缩放等，您可以在效果控件(Effect Controls)中进行更改。以下是如何使用这些控件。
- 导航到效果控件(Effect Controls)面板。
- 查看您的经纱稳定(Warp Stabilization)效果，如果还没有打开下拉菜单。
在这里，您会看到一些可以更改的选项以获得不同的稳定效果。
稳定下拉 (Stabilization Dropdown )
这里的第一个选项是Result。这是您希望对视频产生影响的动作类型。您可以选择Smooth Motion或No Motion。
接下来，您可以更改运动的平滑程度。如果您想要更多微妙的稳定效果，您可以将此平滑(Smoothness)效果更改为较小的值。
然后是方法(Method)选项。这是使用Warp Stabilizer效果的一个重要方面，因为每种稳定方法在不同类型的情况下都有用。
Position方法仅使用视频中的位置数据来稳定它 。
“位置”、“缩放”和“旋转(Position, Scale, and Rotation)”方法使用所有这三个方法中的数据来稳定您的剪辑。
Perspective方法将固定视频的帧以稳定镜头的跟踪。
Subspace Warp方法仅稳定它分析的部分视频抖动，以使整个视频更加均匀。
通过为剪辑选择正确的方法，您将获得更自然的效果。例如，当使用Warp Stabilization时，您不希望视频看起来更流畅，但仍然有太多的运动并分散了主体的注意力。如果您尝试了所有可用的方法并且视频剪辑仍然看起来像这样，它可能太不稳定而无法保存。
方法(Method)下方的保留比例(Preserve Scale)复选框将保留原始素材的比例。有时，使用特定方法(Method)会改变素材的比例以获得更好的结果。您可以选中Preserve Scale，但它可能会导致视频看起来不正常。但这取决于剪辑本身。
边框下拉(Borders Dropdown)
使用Warp稳定器时，Premiere将通过裁剪视频的边界来改变它们以实现更好的稳定性。但是，如果您发现视频周围出现黑条，请转到“框架(Framing)”部分进行调整。
如果您选择了仅稳定(Stabilize Only)选项，这是黑条背后最可能的原因。不幸的是，Premiere不会缩放视频以将其取出，因此您仍会看到它们。
稳定，裁剪(Stabilize, Crop)选项可能会导致更明显的黑条。除了稳定之外，它还裁剪素材(crops the footage)以获得更稳定的效果，但不会缩放素材以隐藏裁剪。
如果您选择Stabilize、Crop、Auto-Scale，Premiere将缩放素材以取出条形。但是，这可能会导致视频分辨率低。
如果您选择Stabilize、Synthesize Edges，Premiere将根据您的视频添加像素并移除黑条。但是，此选项需要更多的处理能力。但是，要知道选择此选项将禁用自动缩放部分以及Crop Less Smooth More。
在框架(Framing)下拉列表下方，您会看到Auto-scale。这告诉您您的视频已被缩放了多少。您可以打开此下拉菜单来更改最大比例(Maximum Scale)级别。您还可以更改Action-Safe Margin，这将为视频添加边框。
如果您愿意，您可以向下更改附加比例(Additional Scale)并进一步缩放视频。
高级选项(Advanced Options)
为了获得更好的稳定性，您需要牢记以下几个选项。
首先，有详细分析(Detailed Analysis)复选框。如果开启这个，Premiere会做更深入的分析，让你获得更好的防抖效果。但是，这将使用更多的处理能力并导致更长的渲染时间。
如果您选择了Framing下的(Framing)Synthesize Edges选项，您还可以在此处更改Input Range以确定(Input Range)Premiere将使用多少秒来创建新边缘的正向和反向视频。
您还可以选择隐藏在视频稳定时出现的警告横幅。

抖动(Shaky)的视频是您在视频项目中最不想看到的事情之一，但有时很难避免意外的摄像机移动，尤其是在拍摄手持镜头时。值得庆幸的是，如果电影制作人和视频编辑人员(video editors)使用变形稳定器，他们可以依靠Adobe Premiere Pro CC来帮助稳定视频。(Adobe Premiere Pro CC)它使稳定过程变得简单，并且可以保存视频片段。
How to Stabilize Video in Premiere Pro
Playing back your recorded videos just tо find out some of them have that dreaded camera shakiness? Sometimes, nо matter how good your hаndiwork is, ѕituations happen where your video comes out a bit off-kilter. This can make your video look less professional, be distracting, or blur your subject – all things you want to avoid.
The creators of the video editing software Adobe Premiere Pro foresaw this situation and graciously included a method to stabilize your shaky footage in post-production. It works very well for minimal to medium shakiness and can really make your final piece look yards more polished. In this Premiere Pro tutorial, we’ll show you how to apply and use this stabilization effect during video editing.
How to Stabilize Shaky Video
Before starting, you’ll want to make sure the video clips you’ll be using are imported into Premiere. Go to the Media Browser. Search your computer for the video files you’re using. Select and drag the files into your timeline. They will automatically be imported into the project files as well.
Now that you have your clips imported and in your timeline, you can begin to stabilize them using Warp Stabilizer in Premiere. Follow these steps to do so.
- Decide which clip(s) you need to be stabilized and select it.
- Go to the Effects panel, and go to Video Effects > Distort > Warp Stabilizer.
- Click and drag it onto the clip and the effect will be applied.
Premiere will take a few seconds to analyze the video and then stabilize it for you. You can then play it back in the Preview panel to see if you like the results. If something is off, there are a few ways you can edit this effect in the Effect Controls panel to make it look exactly the way you want.
How to Edit the Stabilization Effect
If you want to change anything about the stabilization effect, such as the movement, method of stabilization, borders, scaling, or more, you can change these in the Effect Controls. Here’s how to use these controls.
- Navigate to the Effect Controls panel.
- Look under your Warp Stabilization effect and open the dropdown if it’s not already.
Here, you’ll see a few options you can change to get a different stabilization effect.
Stabilization Dropdown
The first option here is Result. This is the type of motion you want the effect to have on your video. You can choose either Smooth Motion or No Motion.
Next, you can change how smooth the motion is. If you want a bit more of a subtle stabilization effect, you can change this Smoothness effect to a lesser value.
Then there is the Method option. This is an important aspect of using the Warp Stabilizer effect, as each stabilization method can be useful in different types of situations.
The Position method uses only position data within your video to stabilize it.
The Position, Scale, and Rotation method uses data from all three of these to stabilize your clip.
The Perspective method will corner pin the frame of your video to stabilize the tracking of the shot.
The Subspace Warp method stabilizes only parts of the video that it analyzes to be shaky to make the whole video more uniform.
By selecting the correct method for your clip, you’ll get a more natural-looking effect. For instance, when using Warp Stabilization, you don’t want a video that, while looking smoother, still has too much movement and distracts from the subject. If you try all the methods available and the video clip still looks like this, it may be too shaky to save.
The Preserve Scale check box underneath Method will retain the scale of your original footage. Sometimes, using a specific Method will alter the scale of footage to get a better result. You can check off Preserve Scale, but it may cause the video to look off. But this depends on the clip itself.
Borders Dropdown
When using Warp stabilizer, Premiere will alter the borders of your video by cropping them to achieve better stabilization. However, if you notice black bars around your video, go to the Framing section to make adjustments.
If you have the Stabilize Only option selected, it’s the likeliest reason behind the black bars. Unfortunately, Premiere doesn’t scale the video to take them out, so you’ll still see them.
The Stabilize, Crop option can cause even more pronounced black bars. In addition to stabilization, it also crops the footage to get a more stable effect yet doesn’t scale the footage to hide the crop.
If you select Stabilize, Crop, Auto-Scale, Premiere will scale the footage to take out the bars. As a result, though, this can result in a low-resolution video.
If you select Stabilize, Synthesize Edges, Premiere will add pixels based on your video and remove the black bars. However, this option takes more processing power. However, know that choosing this option will disable the auto-scale section as well as Crop Less Smooth More.
Below the Framing dropdown, you’ll see Auto-scale. This tells you how much your video has been scaled. You can open this dropdown to change the Maximum Scale level. You can also change the Action-Safe Margin, which will add a border to the video.
You can go down to change the Additional Scale and scale the video even more if you wish.
Advanced Options
Here are a few options you’ll want to keep in mind to get better stabilization.
First, there is the Detailed Analysis checkbox. If you turn this on, Premiere will do a more in-depth analysis to get you a better stabilization effect. However, this will use more processing power and cause longer render times.
If you chose the Synthesize Edges option under Framing, you could also change the Input Range here to determine how much of the video both forward and backward in seconds Premiere will use to create new edges from.
You can also choose to hide the warning banner here that appears while the video is being stabilized.
