Auto Contrast Dynamically adjusts contrast and vibrance, helping you achieve well-balanced visuals without tedious keyframing.
Place this on a clip that appears too dull, dark, or otherwise washed out. Set Intensity to 100 as a starting point while playing the clip, then decrease Intensity as desired. Finally, adjust Vibrance to get the right look.
Intensity increases the relative strength of the automatic contrast for each frame. If you see little or no effect, that means the image already has high contrast. In footage with varying contrast throughout, such as walking from inside a house to the sunny outdoors, Auto Contrast helps compensate and evens things out.
Vibrance is a special type of saturation that boosts natural tones without appearing harsh. You can also decrease it if you want the image to appear duller.
