Waveform

The waveform plots the brightness of the image, each column of the waveform corresponds to a column of pixels in the source video. The pixels of each column are then plotted in a scale from 0 to 110 IRE. The range from 0 to 7.5 IRE is highlighted in blue and indicates a black value that is below traditional NTSC broadcast range. The range from 100 to 110 IRE is highlighted in red and indicates a white value that is above broadcast range. For most analog media the intended pixel luminsotiy values should exist between 7.5 and 100 IRE. You may also select 'Field Split' option which will depict fields 1 and 2 separately (field 1 on top, field 2 on bottom).
