Adjust effects

Auto Color, Auto Contrast, and Auto Levels effects

The Auto Color, Auto Contrast, and Auto Levels make quick global adjustments to a clip. Auto Color adjusts the

contrast and color of a clip by neutralizing the midtones and clipping the white and black pixels. Auto Contrast

adjusts the overall contrast and mixture of colors, without introducing or removing color casts. Auto Levels automat-

ically corrects the highlights and shadows. Because Auto Levels adjusts each color channel individually, it may

remove or introduce color casts.

Each effect has one or more of the following settings:

Temporal Smoothing Specifies the range of adjacent frames that Adobe Premiere Pro analyzes to determine the

amount of correction needed for each frame, relative to its surrounding frames. For example, if you set Temporal

Smoothing to 1 second, Adobe Premiere Pro analyzes the frames 1 second before the displayed frame to determine

the appropriate adjustments. If you set Temporal Smoothing to 0, Adobe Premiere Pro analyzes each frame indepen-

dently, without regard for surrounding frames. Temporal smoothing can result in smootherlooking corrections over

time.

Scene Detect Specifies that Adobe Premiere Pro ignores scene changes when you have enabled Temporal

Smoothing.

Snap Neutral Midtones (Auto Color only) Specifies that Adobe Premiere Pro finds an average nearly neutral (gray)

color in an image and adjusts the gamma values of that color to make it neutral.

Black Clip and White Clip Specify how much the effect clips the shadows and highlights to the new extreme shadow

(level 0) and highlight (level 255) colors in the image. Larger values produce an image with greater contrast.

Blend With Original Specifies the percentage of the effect to apply to the image.

Brightness & Contrast effect

The Brightness & Contrast effect adjusts the brightness and contrast of the entire clip. The value 0.0 indicates that

no change is made.

Channel Mixer effect

The Channel Mixer modifies a color channel using a mix of the current color channels. Use this effect to make

creative color adjustments not easily done with the other color adjustment tools. Create high-quality grayscale

images by choosing the percentage contribution from each color channel, create high-quality sepia-tone or other

tinted images, and swap or duplicate channels.

The Channel Mixer settings are the following:

Red, Green, Blue Specifies the contribution of the individual source channel to the output channel.

Constant Specifies the base amount of the input channel to be added to the output channel.
