Key terms to know.
Whether you’re using a vectorscope or another color correction tool during video editing, there are a few important terms to know. First, color correction is the process of altering the colors of an image within a film. Color correction, along with other editing choices, provides consistency and sets the tone for the film.
Color grading is like a supercharged version of color correction. Grading refers to altering a film to match a tone or theme. Most edits will often use a combination of both.
Here are a few more key terms:
- Additive color: A color created by combining the primary colors of red, blue, and green.
- Chroma: Also known as chrominance, this is the color information within a shot.
- Color gamut: The entire range of colors and brightness that can be displayed on a device. It’s important for a colorist to stay within this scope.
- Dynamic range: The range between maximum and minimum light intensity in a video image.
- Luminance: Also called luma, this is the brightness of a color.
- White balance: The process of making sure whites are represented as the human eye would perceive them in context.
Maintain the balance.
There are two important aspects to understand when reading a vectorscope: hue and saturation. In Adobe Premiere Pro, for example, vectorscopes will give two pieces of information.
1. The scope is structured like a color wheel, and the marker on the monitor will point in a specific direction that indicates the hue of the clip you’re working with. Hue is the primary color that is present within the clip.
2. The length of the marker indicates saturation. Saturation refers to the intensity of a given color. So, if your vectorscope shows a long marker pointing toward green, the hue and saturation of your clip are predominantly green.
