Apple Final Cut Pro 7 - Manual (Page 1330)

Different third-party video interfaces have different controls for adjusting the video signal
being captured.
• If your video interface uses Brightness and Contrast sliders: Make the following adjustments.
• Adjust the Brightness slider so that all of the bars in the Waveform Monitor are set
near the upper purple targets in the background.
• Adjust the Contrast slider so that the tops of the bars and the bottoms in the
Waveform Monitor are within the boundaries of the top and bottom targets.
• Continue adjusting the Brightness and Contrast sliders until there is an acceptable
range of brightness between the 100 and 0 percent targets.
• If your interface uses Black Level and White Level sliders: Make the following adjustments.
• Adjust the Black Level slider so that the third bar from the left is at the 0 percent
target toward the bottom of the Waveform Monitor.
• Adjust the White Level slider so that the second bar from the left is at the 100 percent
target at the top of the Waveform Monitor.
6 Adjust the clip’s hue and saturation using the Vectorscope for reference.
The Vectorscope is on the right and displays the color values of the different areas of the
video frame as a point graph. Each point on the circular graph represents one of the color
bars. The goal is to line up these points with their respective targets.
• Adjust the Hue slider to rotate the points around the center of the graph.
• Adjust the Saturation slider to move the points closer to or farther from the center of
the graph. If this slider is properly adjusted, each point falls within a purple target box.
Adjusting Capture Settings on Source Tapes Without Color Bars
If there are no color bars on your source tapes, you can adjust your tapes using the flesh
tones of people in the shot. As long as a person’s skin tones look accurate, chances are
the rest of the colors in that shot will look fine. To help you find the correct flesh tone, a
special marker appears in the Vectorscope to the left of the center of the Vectorscope
scale. This line indicates the hue of a person’s skin tones.
