Tutorial: Adjusting Color and Brightness in Adobe Premiere Pro CS5.5

When you compress video for the web, the video can darken and colors can become muted. 在本教程中, I'll show you how to correct color and adjust brightness and color saturation with Adobe Premiere Pro's Fast Color Corrector.

When you compress video for the web, the video can darken and colors can become muted. 在本教程中, I’ll show you how to correct color and adjust brightness and color saturation with Adobe Premiere Pro’s Fast Color Corrector. 如果你是Final Cut Pro 7的用户, I’ll also show you that Premiere Pro’s tools work very similarly to those that you’re used to and should be much easier to learn than those used in Final Cut Pro X. 让我们来看一看.

图1(下面) 显示了我们将要处理的片段, which was shot at 流媒体 West in Los Angeles last year. 有两个问题:首先, the color is a bit off—the sign is white and not brown—and second, 我的脸有点太黑了. So we’ll fix both of those with the Fast Color Corrector.

工作在Premiere Pro的波形监视器

在Premiere Pro中调整亮度之前, open the Waveform monitor by first selecting Window > Reference monitor. The Reference monitor opens with composite video showing; change it to the Waveform monitor by clicking the Output button and selecting YC Waveform 图2(下面).

The Waveform monitor shows the Brightness value of the pixels on a scale from 0–100 IRE, 0是黑色. (The Brightness value of the black you see in 图2 is 7.5.) After the adjustments that we’ll make in the Waveform monitor, the black portions of the image will be close to zero and the whites will be close to 100. You can see my face in the Preview Monitor on the right, which is represented by the clump of pixels circled in 图3(下面). 如果我前后移动视频, 那一团像素随着我的头移动而移动, which highlights the fact that the horizontal location of the pixels in the video corresponds to where they’re located in the Waveform monitor. So it’s pretty easy to see exactly what you’re adjusting in the Waveform monitor and that’s helpful for a couple of reasons that we’ll discuss throughout the tutorial.

现在让我们来调整波形. I prefer to show only brightness adjustments so I’ll deselect the Chroma checkbox at the top of the Reference monitor (下面的图4).

I like my blacks to be set at zero IRE, so I’ll click set up and bring the blacks down to 0. I like the intensity set to 100 because it’s easier to read, but these are subjective and you can find the settings that work best for you. 当我们观察波形时, 我们关心两件事:第一, 我们希望白人最多能接近100人. 第二个, we want the blacks to be around zero; once the blacks come off of zero, 一切都开始褪色. 无论你做什么调整, you want to make sure that blacks portions of the image stay at zero, 对我这种肤色的人来说, 你希望脸的斜度在70到80度之间. 所以当我说脸太黑时, basically what I’m saying is that the values are clumped between 50 and 60 and I would prefer to see them between 60 and 70, 或者65-75.

We need to adjust the face without pulling the blacks off of the 0 IRE value and without boosting the whites way into the 110 or 120 range.
