Vector Scope

Zebra Pattern

Zebra pattern is a feature that overlays some stripes onto the image that indicate exposure levels. Areas that are close to overexposure will be laid a striped pattern acting as a warning indicator to the user that the highlights are blown out and not recorded and the user should adjust the exposure accordingly. The zebra function is a very useful feature in checking the amount of brightness to which the subject has been exposed.

Histogram

A histogram is a graphical representation of the tonal values of your image. Dark tones are displayed on the left side and tones get lighter as you move rightward. Vertical axis displays the amount of tones . In general, an evenly distributed image should yield a bell-shaped curve as most tones should gather in the middle portion of the histogram between darkest and lightest tones.

RGB Parade

The RGB parade is a helpful tool to separate out the three color channels of digital video in order to improve your video edits.

Vector Scope

The Vector Scope is used to measure Hue and Saturation in a video image. The proximity a signal to the color markers on the rim indicate what color it is. If the signal gathers at the center, it means the video image has no color information or simply black-and- white. It may not help if your video image contains too much skin tones but it is definitely a good tool for monitoring the image colors.
