become a neutral black. Like using the White Balance control, these adjustments affect all the colors in the clip.
You can also click the color swatch next to the eyedroppers and use the Adobe Color Picker to select a sample color.
Make quick luminance corrections
The Fast Color Corrector and the Three-Way Color Corrector effects have automatic controls for making quick adjustments to the luminance in a
clip. For a video on correcting color and luminance with the Fast Color Corrector, see the
Adobe website .
1. Select the clip in a Timeline panel and apply either the Fast Color Corrector or the Three-way Color Corrector. See also Apply effects to
clips .
2. In the Effect Controls panel, click the triangle to expand the Fast Color Corrector or the Three-way Color Corrector controls.
3. (Optional) Select the Show Split View option if you want to view a before and after comparison of your adjustment in the Program Monitor.
You can specify whether the split view is horizontal or vertical by choosing from the Layout menu. You can also adjust the relative proportion
of the before and after views.
4. Click any of the following buttons to quickly adjust the luminance to broadcast standards:
Raises the black levels in a clip so the darkest levels are above 7.5 IRE. A portion of the shadows is clipped and the
intermediate pixel values are redistributed proportionately. As a result, using Auto Black Level lightens the shadows in an image.
Applies both the Auto Black Level and Auto White Level simultaneously. This makes the highlights appear darker and
shadows appear lighter.
Lowers the white levels in a clip so the lightest levels do not exceed 100 IRE. A portion of the highlights is clipped and
the intermediate pixel values are redistributed proportionately. As a result, using Auto White Level darkens the highlights in an image.
Color balance, angle, and saturation controls
The Fast Color Corrector and the Three-way Color Corrector effects offer Hue Balance and Angle color wheels and a Saturation control for
balancing color in your video. Color balance is just what its name implies, balancing the red, green, and blue components to produce the desired
color of white and neutral grays in the image. Depending on the desired effect, you may not want the color balance in a clip to be completely
neutral. Perhaps you want an intimate family scene to have a warm (reddish) color cast or maybe the scene in your crime documentary requires a
cool (bluish) color cast.
When making adjustments with the color wheel and Saturation control, it’s useful to open a Reference Monitor to view the Vectorscope ganged
to the composite video in the Program Monitor.
The color wheel adjustments offer the following adjustments:
Rotates the color toward a target color. Moving the outer ring to the left rotates the colors toward green. Moving the outer ring to the
right rotates the colors toward red.
Controls the intensity of the color introduced into the video. Moving the circle out from the center increases the magnitude
(intensity). The intensity can be fine-tuned by moving the Balance Gain handle.
Affects the relative coarseness or fineness of the Balance Magnitude and Balance Angle adjustment. Keeping the perpendicular
handle of this control close to the center of the wheel makes the adjustment very subtle (fine). Moving the handle toward the outer ring makes the
adjustment very obvious (coarse).
Shifts the video color toward a target color. Moving the Balance Magnitude circle toward a specific hue shifts the color
accordingly. The intensity of the shift is controlled by the combined adjustment of the Balance Magnitude and Balance Gain.
