Apply the Color Correction effects
The following procedure is a general
overview of applying the Color Correction effects. See the following
sections in this chapter for making adjustments using the specific
controls.
- Set up your workspace for color correction. If
possible, make sure a calibrated NTSC or PAL monitor is connected
to your computer.
- Apply one of the Color Correction effects to the clip
in a Timeline panel.
Note: If the clip is already selected in a Timeline panel,
you can drag the effect to the Video Effects area of the Effect
Controls panel.
- In the Effect Controls panel, expand the Color Correction
effect.
- Move the current‑time indicator to a frame that provides
the best example of colors that need to be adjusted.
- (Optional) Do any of the following to set preview options
when correcting color:
To view only the luminance values in a
clip, choose Luma from the Output menu. This option only affects
the preview in the Program Monitor, it doesn’t remove the color
from the video.
To display a before and after view of the clip in
one monitor, select the Show Split View option. You can specify
whether the split view is horizontal or vertical by choosing from
the Layout pop‑up menu. You can also adjust the relative proportion
of the before and after views.
- (Optional) Use the Tonal Range Definition control to
define the shadow, midtone, and highlight areas in the clip. You
can choose Tonal Range from the Output menu to view the tonal ranges
you defined. Once defined, choose from the Tonal Range menu to restrict
the color corrections to a specific tonal range. See also Define the tonal ranges in a clip.
Note: Only the Luma Corrector, RGB Corrector, and Three‑Way
Color Corrector effects let you apply adjustments to a specific
tonal range.
- (Optional) Click the triangle to expand the Secondary
Color Correction controls if you want to correct the exposure for
a specific color or range of colors. Use the Eyedropper tool or
the other Secondary Color Correction controls to specify the colors
to correct. See also Specify a color or range of colors to adjust.
Note: All Color Correction effects have Secondary Color
Correction controls except the Fast Color Corrector effect and Video
Limiter effect.
- Do any of the following:
To adjust color balance and saturation
using color wheels, adjust the Hue Balance and Angle wheels or numeric
controls in the Fast Color Corrector or Three‑Way Color Corrector
effect. See also Color balance, angle, and saturation controls.
To adjust luminance or color using a curve control,
use the curve adjustments in the Luma Curve or RGB Curves effect.
See also Adjust color and luminance using curves.
To adjust luminance by setting the black, gray,
and white levels, use the levels controls in the Fast Color Corrector
or the Three‑Way Color Corrector effect. See also Adjust luminance using levels.
See Luma
Corrector effect and RGB
Color Corrector effect.
To adjust luminance or color
using numeric controls, use the controls in the Luma Corrector or
RGB Color Corrector effect.
 Use keyframing
to animate your color correction adjustment. This is especially useful
when the lighting changes in a clip. See also About
keyframes.
- (Optional) Apply the Video Limiter effect after you’ve
made your color corrections to make the video signal conform to
broadcast standards while preserving as much of the image quality
as possible. It’s recommended to use the YC Waveform scope to make
sure the video signal is within the 7.5 to 100 IRE levels.
