Vectorscope

A vectorscope display. This display plots chroma values (U/V color placement) in two dimensional graph (which is called a vectorscope). It can be used to read of the hue and saturation of the current frame. The whiter a pixel in the vectorscope, the more pixels of the input frame correspond to that pixel (that is the more pixels have this chroma value). The V component is displayed on the vertical (Y) axis, with the bottom edge being V = 0 and the top being V = 255. The U component is displayed on the horizontal (Y) axis, with the left representing U = 0 and the right representing U = 255. Six blocks are highlighted to depict standardized color points for red (90, 16), green (54, 222), blue (240, 146), cyan (166, 240), magenta (202, 44), and yellow (16, 110). All valid chroma values fall within a circlular shape from the center to the outer edge of the plot.You may also select 'Field Split' option which will depict fields 1 and 2 separately (field 1 on top, field 2 on bottom).
