Lumetri Scopes is a tool set in Premiere Pro for analyzing video colors and brightness, including Waveform, Vectorscope, Histogram, and Parade. 1. Waveform is used to view the brightness distribution and judge overexposure or underexposure; 2. Vectorscope observes the color saturation and tone distribution; 3. Histogram displays the overall brightness distribution; 4. Parade analyzes the brightness levels of the red, green and blue channels. Opening is to click on the "Window" in the top menu bar and select Lumetri Scopes. It is recommended to set it to display the current frame of the Program Monitor to stably observe the details. When using, you can adjust the parameters with Lumetri Color, and refer to the standard range to ensure picture quality, helping to make color adjustment more accurate and reliable.

During the editing process, it is very important to accurately grasp the color and exposure of the video. Lumetri Scopes is a very practical tool in Premiere Pro, which can help you intuitively see information such as brightness, color distribution, etc. of the picture. If you want to make color adjustments more professional, or just want to make sure the picture is not in trouble, then this panel is your "eyes".

What is Lumetri Scopes?

Lumetri Scopes is a set of image analysis tools provided by Premiere Pro, which are used to display video color, brightness, waveform and other data in real time. It is not as susceptible to ambient light as the naked eye, but uses charts to tell you what the picture looks like.

Several common Scopes include:

• Waveform : Check the brightness distribution and determine whether it is overexposed or underexposed
• Vectorscope : Observe color saturation and tone distribution
• Histogram : Understand the overall brightness distribution
• Parade : View the brightness levels of the red, green and blue channels respectively

These tools can help you make more accurate color tuning decisions rather than just relying on feelings.

How to turn on and set up Lumetri Scopes?

To use Lumetri Scopes, first find it. You can open it in the following ways:

1. Click the window (Window) at the top menu bar
2. Select Lumetri Scopes from the drop-down menu

By default, it may be a separate panel. You can drag it next to the program monitor to make it easier to refer to data while watching the screen.

In addition, it is recommended to set Scopes to display the currently previewed screen frame instead of refreshing dynamically during playback. This allows for more stable observation of details. The setting method is to click the pinion icon in the upper right corner of the Scopes panel and check Use Frame from Program Monitor .

How to understand several key Scopes?

Waveform: Is the brightness normal?

Waveform displays the brightness change of the screen from left to right. The vertical direction represents the brightness value (0~100%). If most of the content is concentrated above, it means that the picture is bright and there may be highlights overflow; if concentrated below, it may be too dark.

• If the waveform exceeds 100%, it means that some areas have been overexposed (details are missing)
• If the entire waveform is pressed on the bottom, the picture will appear gray or dark

It is recommended to look at Waveform before tuning the color, and keep it in a reasonable range when adjusting the brightness.

Vectorscope: Is the color natural?

Vectorscope presents the saturation and hue of the color. The closer the center is, the grayer the color is, and the more bright the outward. Different colors are distributed in different directions, such as red, green, and blue each occupy a corner.

• If the pointer points in a certain direction and is very long, it means that the color is very thick
• If the dots are scattered, it may be that the colors are not coordinated.

When adjusting colors, you can use it to determine whether the skin color is natural or whether the overall color is biased to a certain color.

Histogram: The overall brightness distribution is clear at a glance

Histogram is similar to the histogram in the camera, with black on the left and white on the right, and mid-toned in the middle. If the bar chart is piled on the left, the picture is dark; if the histogram is piled on the right, it is bright.

• When there is a large area of black or white in the image, "fault" may occur, which is normal
• If there is an empty piece in the middle of the bar chart, it may be a loss of details caused by excessive stretching.

Tips for practical use

• Use with Lumetri Color : While adjusting parameters in Lumetri Color, you can find the appropriate value faster while observing the changes in Scopes.
• Reference standard range : For example, broadcast-level video requires that the brightness must not exceed 100IRE, which can be strictly controlled in Waveform.
• Switch Scope type to quickly check : Sometimes you can find problems by just a glance, such as yellow skin tone, which can be found immediately in Vectorscope.

Basically that's it. Lumetri Scopes looks a bit complicated, but once you get familiar with the meaning of each chart, you will find that it is actually a very direct visual aid. At the beginning, you may need to compare several more pictures to practice your skills, and you will gradually develop the habit of watching Scope.
