颜色是任何视频的重要组成部分，因为它可以吸引观众并吸引观众。创造性地使用颜色也是一种经典的讲故事技巧(storytelling technique)，因为颜色可以用来引发某些情绪反应。因此，确保您在视频项目中有意使用色彩效果非常重要。
Adobe Premiere Pro CC有大量颜色分级(color grading)工具供您使用。它们允许您调整黑白、色调、亮度等。在本文中，您将了解这些工具的用途、用途以及如何使用它们在视频编辑(video editing)中进行调色。
使用 Lumetri 颜色(Using Lumetri Color)
对于Premiere中的(Premiere)颜色分级(color grading)，您需要熟悉Lumetri 颜色(Lumetri Colo)面板(r panel)。您可以通过选择Premiere顶部的颜色(Color)工作区来找到它。在此面板中，您可以使用一些不同的功能来更改所选剪辑中的(clip or clips)颜色(way color)外观。
基本校正(Basic Correction)
此功能允许您对视频剪辑(video clip)中的颜色进行基本的常规更改。您可以更改的更改包括白平衡、色调和饱和度(tone and saturation)。这也是您可以导入 LUT 的(import a LUT)地方，这是您可以下载并在项目中使用的预制色彩校正设置。(color correction)这是修复肤色等基础知识的好方法。
有创造力的(Creative)
在创意(Creative)下拉菜单下，您可以选择外观(Look)或上传外观。这些是使您的剪辑看起来具有某种方式的简单方法，而无需处理所有设置。这些在技术上也是LUT(LUTs)，但它们改变了更多的外观，而(appearance whereas) LUT(LUTs)本身往往是更基本的颜色校正(color correction)。
您还可以在此处更改“调整(Adjustments)”下的设置，例如褪色胶片、锐化、鲜艳度和饱和度。您还可以在此处更改阴影和高光色调(shadow and highlight tints)。
曲线(Curves)
这些设置一开始使用图表可能看起来有点吓人，但是一旦您开始使用曲线，您就会很快了解它们的作用。曲线非常适合进行详细的编辑并使您的视频剪辑(video clip)看起来像您想要的那样。
一般来说，图表的左下角是调整阴影的位置，中间是中间色调，右上角是高光。如果您是第一次使用曲线，进行细微的更改可能会更加困难，因此请尝试使用曲线进行较大的更改，以便您可以看到剪辑的哪个部分正在被更改。
色轮和匹配(Color Wheels & Match)
在这里，您可以更改阴影、中间色调和高光的色调，以及这些色调的强度。您还可以使用颜色匹配(color match)将这些设置与时间线中的其他剪辑相匹配。
为此，首先选择要作为颜色参考点(reference point color-wise)的剪辑。然后，在时间线中选择另一个剪辑以匹配参考剪辑(reference clip)，然后选择应用匹配(Apply Match)。
HSL 中学(HSL Secondary)
此功能可在完成基本色彩校正(color correction)后使用。它允许校正特定颜色而不是整体图像。首先(First)，您可以使用吸管工具或选择颜色通道(color channel)来选择颜色。然后，您可以使用滑块调整色调、饱和度和亮度。
然后，您还可以去噪或模糊，并使用色轮(color wheel)校正所选颜色(chosen color)。
小插图(Vignette)
如果您想添加晕影作为视频效果(video effect)，这里有一些选项可以执行此操作，您可以更改数量、中点、圆度和羽化等设置。
使用 Lumetri 范围(Using the Lumetri Scopes)
您想学习如何在Adobe Premiere中使用的另一个颜色分级工具是Lumetri示波器。这些是波形图(waveform graphs)，可向您显示视频剪辑中的确切亮度级别。您可以在Premiere(Premiere)中使用几种不同的示波器，但主要的是Parade 和 Vecterscope(Parade and Vecterscope)。
Parade 示波器(Parade scope)可让您在视频图像中看到红色、绿色和蓝色波形并排显示，(video image)以便您轻松比较它们。图表上的 0 表示黑色，一直到 100 或完全白色。
当您使用Lumetri(Lumetri)工具更改颜色时，您将能够看到这些波形根据您所做的更改而移动。您使用此功能的次数越多，查看图表并了解它如何转换为您的图像就越容易。
另一个需要了解的重要范围是Vectorscope。这是一个圆形范围，可显示您选择的视频图像(video image)落在色轮的哪些部分。它还显示视频中的饱和度。更鲜艳的颜色将远离轮子的中心，而黑白图像将是死点。
导入和使用 LUT 的教程(Tutorial for Importing and Using LUTs)
LUT(LUTs)是一种简单的方法，可以让您的项目进行整体的基本颜色校正或调整(color correction or adjustment)，而不会自己弄乱Lumetri 颜色(Lumetri Color)设置。要使用LUT(LUTs)，您首先要找到一些在线下载。您可以找到免费或高级LUT(LUTs)，由您决定选择哪些。只需(Just)确保从信誉良好的来源下载它们即可。
下载 LUT 后，请按照以下步骤在 Premiere 中使用其中一个：
1. 转到Lumetri Color > Basic Correction > Input LUT。
2. 单击下拉菜单并选择浏览( Browse)。
3. 在文件资源管理器(file explorer)中，找到您要使用的LUT并选择它。(LUT)然后它将应用于您的剪辑。
LUT可用作进一步颜色校正和颜色分级(color correction and color grading)的起点(jumping-off point)。简单地(Simply)将LUT添加到您的剪辑并停在那里可能会使您的颜色看起来不一致(color look inconsistent)，因为根据剪辑的原始照明和颜色，每个剪辑上的(lighting and coloring)LUT看起来并不相同。因此，在添加LUT之后，您需要检查您的剪辑并从那里进行颜色校正(color correct)，以免出现任何不一致。
什么时候应该进行颜色分级？(When Should You Color Grade?)
您可能想知道在视频编辑过程中的什么时候应该开始考虑颜色分级(color grading)。说实话(Truthfully)，您可以在编辑时的任何时候开始，但在所有剪辑编辑完成并固定下来后 ，仅对颜色分级是更好的工作流程。(color grade)
如果您正在编辑LOG 素材(LOG footage)或许多专业相机拍摄的去饱和、中性素材，则尤其如此。这将需要更多的颜色分级工作来获得完成的外观，并且如果您需要更改(grading work)剪辑顺序或长度(clip order or length)等内容，您将不希望进行大量的后退步骤。
因此，在开始色彩工作(color work)之前，请确保您的素材已按照您希望的方式完全编辑。它应该是您编辑工作流程中的最后一步。
Adobe Premiere 中的颜色分级以获得更好的视频(Color Grading in Adobe Premiere For a Better Video)
Premiere是可用于对素材进行颜色分级的最佳程序之一，因为它有多种颜色工具可用于此目的。无论(Whether)您只是需要一些基本的修正还是想对您的视频进行创意改造，上述工具都将帮助您在自己的视频制作(video production)中实现它。
How to Color Grade in Adobe Premiere Pro
Color is an important part оf any videо, as it can attract viewers and engage your audience. Creative use of color is also а сlassiс storytelling technique, as color can bе used to elicit certain emotional responseѕ. So, making sure you’re υsing color effects deliberately in your video projects is important.
Adobe Premiere Pro CC has plenty of color grading tools for you to use. They allow you to adjust blacks and whites, hues, brightness, and more. Throughout this article, you’ll learn what these tools are, what they’re for, and how to use them to color grade in your video editing.
Using Lumetri Color
For color grading in Premiere, you’ll want to acquaint yourself with the Lumetri Color panel. You can find this by selecting the Color workspace at the top of Premiere. In this panel, there are a few different features you can use to change the way color looks in a selected clip or clips.
Basic Correction
This feature allows you to make basic, general changes to the color within your video clip. Changes you can alter include white balance, tone and saturation. This is also where you can import a LUT, which are pre-made color correction settings you can download and use in your project. This is a good way to fix basics like skin tones.
Creative
Under the Creative dropdown, you can choose a Look or upload one. These are easy ways to make your clip look a certain way without having to deal with all the settings. These are technically also LUTs, but they change more of the appearance whereas LUTs themselves tend to be a more basic color correction.
You can also change settings under Adjustments here such as faded film, sharpen, vibrance, and saturation. You can also change the shadow and highlight tints here.
Curves
These settings may look a bit intimidating at first with the graphs, but once you begin to use curves you’ll understand what they do quickly. Curves are great for making detailed edits and getting your video clip to look just the way you want.
Generally, the bottom-left of the graph is where you will adjust for shadows, the middle for mid-tones, and the top-right for highlights. Making subtle changes may be more difficult if it’s your first time using curves, so try making big changes with curves so you can see what part of your clip is being altered.
Color Wheels & Match
Here you can change the hue of shadows, mid-tones, and highlights, as well as the intensity of these hues. You can also use the color match to match these settings to other clips in your timeline.
To do this, first select the clip you want to be the reference point color-wise. Then, choose another clip in your timeline to match to the reference clip, and select Apply Match.
HSL Secondary
This feature can be used after completing a basic color correction. It allows for correction of a specific color instead of the image overall. First, you can select a color using the eyedropper tool or choosing a color channel. Then you can adjust for hue, saturation, and lightness using the sliders.
You can then also denoise or blur, and use the color wheel to correct the chosen color.
Vignette
If you’d like to add a vignette as a video effect, there are options here to do so and you can change the settings such as the amount, midpoint, roundness, and feathering.
Using the Lumetri Scopes
Another color grading tool you’ll want to learn how to use in Adobe Premiere is the Lumetri scopes. These are waveform graphs that show you the exact levels of lightness in your video clips. There are a few different scopes you can use in Premiere, but the main ones are Parade and Vecterscope.
The Parade scope allows you to see your red, green, and blue waveforms within your video image right beside each other so that you can easily compare between them. The 0 on the graph denotes black and goes all the way up to 100, or completely white.
As you make changes to the colors with Lumetri tools, you’ll be able to see these waveforms move according to the changes you make. The more you use this feature, the easier it will be to look at the graph and understand how it translates onto your image.
Another important scope to know about is the Vectorscope. This is a circular scope which shows you which parts of the color wheel your selected video image falls on. It also shows the amount of saturation in your video. More vivid colors will fall further from the center of the wheel, while black and white images will be dead center.
Tutorial for Importing and Using LUTs
LUTs are an easy way to give your project an overall, basic color correction or adjustment without messing with the Lumetri Color settings yourself. To use LUTs, you’ll first want to find some to download online. You can find both free or premium LUTs, it’s up to you which ones you choose. Just make sure to download them from a reputable source.
Once you have LUTs downloaded, follow these steps to use one in Premiere:
1. Go to Lumetri Color > Basic Correction > Input LUT.
2. Click on the dropdown and select Browse.
3. In the file explorer, find the LUT you wish to use and select it. It will then be applied to your clip.
A LUT can be used as a jumping-off point for further color correction and color grading. Simply adding a LUT to your clips and stopping there may make your color look inconsistent, as the LUT will not look the same on every clip depending on the original lighting and coloring of the clips. So, after adding a LUT, you’ll want to go through your clips and color correct from there so that there aren’t any inconsistencies.
When Should You Color Grade?
You may be wondering at what point in the video editing process you should start to think about color grading. Truthfully you could begin at any point while editing, but it’s better workflow-wise to only color grade after all your clip edits are finished and set in stone.
This is especially true if you’re editing LOG footage, or the desaturated, neutral footage many professional cameras shoot. This will require much more color grading work to achieve a finished look, and you won’t want to have to make massive back steps if you need to change something like the clip order or length.
So, make sure your footage is completely edited the way you want it to be before starting color work. It should be one of the very final steps in your editing workflow.
Color Grading in Adobe Premiere For a Better Video
Premiere is one of the best programs you can use to color grade footage as it has a wide range of color tools available for this purpose. Whether you just need some basic correction or want to give your video a creative makeover, the tools outlined above will help you achieve it in your own video production.
