Auto Color, Auto Contrast, and Auto Levels effects
The Auto Color, Auto Contrast, and Auto Levels effects make quick global adjustments to a clip. Auto Color adjusts
contrast and color 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 automatically
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 The range of adjacent frames, in seconds, analyzed to determine the amount of correction
needed for each frame, relative to its surrounding frames. If Temporal Smoothing is 0, each frame is analyzed
independently, without regard for surrounding frames. Temporal Smoothing can result in smoother looking
corrections over time.
Scene Detect If this option is selected, frames beyond a scene change are ignored when the effect analyzes
surrounding frames for temporal smoothing.
Snap Neutral Midtones (Auto Color only) Identifies an average nearly neutral color in the frame and then adjusts the
gamma values to make the color neutral.
Black Clip, White Clip How much of the shadows and highlights are clipped to the new extreme shadow and
highlight colors in the image. Be careful of setting the clipping values too large, as doing so reduces detail in the
shadows or highlights. A value between 0.0% and 1% is recommended. By default, shadow and highlight pixels are
clipped by 0.1%—that is, the first 0.1% of either extreme is ignored when the darkest and lightest pixels in the image
are identified; those pixels are then mapped to output black and output white. This clipping ensures that input black
and input white values are based on representative rather than extreme pixel values.
Blend With Original Determines the effect’s transparency. The result of the effect is blended with the original image,
with the effect result composited on top. The higher you set this value, the less the effect affects the clip. For example,
if you set this value to 100%, the effect has no visible result on the clip; if you set this value to 0%, the original image
doesn’t show through.
Convolution Kernel effect
The Convolution Kernel effect changes the brightness values of each pixel in the clip according to a mathematical
operation known as a convolution. The Convolution Kernel Settings include a set of controls that represent cells in
a 3x3 grid of pixel brightness multipliers. Labels on the controls, which begin with the letter “M,” indicate their
position in the matrix. The M11 control, for example, affects the cell in the first row and first column of the grid; the
M32 control affects the cell in the third row and second column. The pixel being evaluated falls in the center of the
grid, at the M22 location. Use this effect for fine control over the parameters of various emboss, blur, and sharpen
effects. For a given effect, it is easier to apply one of the Convolution Kernel presets and to modify it, than to create
the effect from scratch using the Convolution Kernel effect itself.
