Brightness and Contrast
Alters the overall color and luminance values of your output media le to a brighter or darker
level. Some QuickTime codecs darken your video le, so you can use this lter to compensate.
Choose any number between –100 and 100, but avoid extreme settings, because they confer a
very washed-out quality.
The Brightness and Contrast lter contains the following controls:
•
Brightness: Adjusts brightness to any number between –100 and 100.
•
Contrast: Adjusts contrast to any number between –100 and 100.
Color Correct Highlights, Color Correct Midtones, Color Correct Shadows
Depending on which of these three lters you choose, corrects white balance inaccuracies and
creates color eects on the bright, midtone, or dark areas of your clip. You can adjust red, green,
and blue values independently between –100 and 100.
The three Color Correct lters contain the following controls:
•
Red: Adjusts the red value between –100 and 100.
•
Green: Adjusts the green value between –100 and 100.
•
Blue: Adjusts the blue value between –100 and 100.
