Checking/Adjusting Brightness and Color

Even a video finely displayed on a PC monitor may cause problems like highlight/shadow detail loss when actually displayed on a TV monitor. Although the best solution is to edit the video in an environment that the final video is screened while checking the screening regulations, in many cases, editing must be performed without such environment and regulation check means. In such cases, use the vector scope or waveform to check the brightness and colors, and perform the editing process.

Checking Brightness and Color

Vector scope and waveform can monitor the brightness and colors, allowing fine adjustment of detailed parts that cannot be seen by eyes.

1Move the timeline cursor and display the image to check the color data on the Recorder.

2Click [Toggle Vector Scope/Waveform Display] on the timeline.

The [Vector Scope/Waveform] dialog box appears.

(1)	Information area	Display the coordinate values and color information of the position where the mouse cursor on the preview window is placed.
(2)	Vector scope	Display color distribution of the image shown in the preview window. The circle represents the color circle, and the distance from the center represents the saturation.
(3)	Waveform	Display chroma and luminance levels of the image on the preview window. No problem will occur when the IRE is within 0 to 100.

Note

Displaying the vector scope/waveform increases the CPU load. Display it only when necessary.

Adjusting Brightness and Color

1In the folder view of the [Effect] palette, click the [Video Filter] tree.

2Click [Color Correction].

3Drag and drop [Color Balance] to the clip (video part) on the timeline.

4Select [Color Balance] in the [Information] palette, and click [Configure].

The [Color Balance] dialog box appears.

5Check [Safe Color].

Make an automatic adjustment to keep the video signal within the YUV color space.

6Click [OK].

Although safe color clips a range of luma (luminance) 16-235 and chroma 16-240, and the chroma is not automatically adjusted within the safe area, it is calculated so that luma/chroma will be within IRE0-100.
