1, color temperature adjustment.
Color temperature refers to the cold and warm colors of the picture, which is usually used to express time, scene and emotional atmosphere. You can change the color and atmosphere of the picture by adjusting the color temperature, such as increasing the blue tone to show the cold environment and weakening the yellow tone to show the psychedelic feeling.
2. Curve adjustment.
Curve adjustment can change the brightness, contrast and saturation of the picture. By adjusting the curve, the brightness of the picture is more balanced, the contrast is clearer and the saturation is more natural. Usually, S-curve adjustment can be used to increase the three-dimensional sense and layering of the picture.
3, color balance adjustment.
Color balance adjustment usually includes brightness, saturation and hue. You can make the color of the picture more natural and balanced during the adjustment process. For example, by adjusting the color balance, you can sell a picture that turns the night picture into a normal tone.
4. Color separation adjustment.
Color separation adjustment can separate different colors of the picture, making the picture clearer, brighter, more saturated and more vivid. This adjustment method needs to consider saturation, color, brightness and other factors at the same time.
5, color scale adjustment.
Color scale adjustment can adjust the black-and-white balance of the picture, making the picture clearer, clearer, brighter and more vivid. By adjusting the color scale, the dark parts or bright parts in the picture can be eliminated, and the balance and optimization of the picture can be achieved.
The purpose of video color matching:
1, improve the picture quality.

By adjusting various parameters of the picture, we can eliminate the color difference, color difference, insufficient brightness and other problems in the picture, and make the picture more full, vivid and clear.
2. Express the emotion of the film.
Through video color matching, the emotion and atmosphere of the film can be expressed, making the film more appealing and expressive. For example, by adjusting the color temperature, tone and other parameters of the picture, the characteristics of the picture, such as warm tone, richness and color depth, can be expressed, so as to achieve the purpose of expressing the emotion of the film.
3, a unified picture style.
In the process of film and television production, the shooting conditions, light and background of the lens are different, and the color, vertical color and brightness of the picture will be different. Through video color matching, we can unify the picture style, make the picture style of the whole film more harmonious and achieve better aesthetic effect. It can also enhance the artistic effect of the picture and make the picture more visual impact, artistic appeal and ornamental.
