Apple Final Cut Pro 7 - Manual (Page 1329)

The Waveform Monitor and Vectorscope appear below the Log and Capture window. On
the left is the Waveform Monitor, which displays the brightness levels of the color bars
within the video frame as a graph. Each “step” of the graph corresponds to one of the
color bars. The goal is to adjust the brightness and contrast so that the levels of the bars
match their ideal targets, shown in purple.

Note: Don’t worry if the graph appears to be “noisy”; this is normal for analog video
played back from tape.
