Apple Final Cut Pro 7 - Manual (Page 1312)

The RGB Parade scope is useful for comparing the relative levels of red, green, and blue
between two clips. If one clip has more blue than another, the difference shows up as an
elevated blue waveform in the one, and a depressed blue waveform in the other. In the
previous screen shot, the overall image contains quite a bit of blue. By comparison, the
shot of the couple dancing below has substantially less blue and far higher levels of red,
which can be seen immediately in the RGB Parade scope.
This image contains
much less blue than
the previous image.

control is helpful for revealing minuscule areas that otherwise might be invisible on the
scopes.

scope.
• Scales brightness: Controls the brightness of the grid lines (known as graticule lines on
traditional video scopes).
