Color correction


Color correction effects are designed to enhance the visual quality of layers by adjusting their colors. Color correction is intended for the initial color manipulation and for fixing problems.

Also see Color grading.

Auto color, contrast & levels

These effects automatically adjust the layer's color, contrast or levels.

The image below shows the different results of auto color, auto contrast and auto levels from top to bottom:

autograding

By default the auto grading effects update on each frame, which can cause fluctuations in the layer's appearance as the contents of the frame change.

By activating the Select frame property you can manually choose a frame to use as the source for the automatic adjustment, which will be used for the duration of the layer.

Brightness & contrast

Quick adjustment of the layer's brightness and contrast.

Color balance

Individually adjust the balance of red, green and blue in the layer's shadows, midtones and highlights.

The Preserve luminosity property retains the layer's original brightness when altering the colors.

Color correction wheels

Requires the Starter pack

This effect provides a visual way to quickly adjust the highlights, midtones and shadows of your layer.

You can drag on the color wheels to adjust the color balance of highlights (top wheel), midtones (middle wheel) and shadows (bottom wheel). The further out from the center of the color wheel you drag the point, the more saturated the colors will become.

The sliders can be used to adjust the strength and lightness of the adjustment, and the rotator on the wheels changes the hue.

Additional controls can be found in the property groups below the wheels, including a white balance property which functions the same as the separate white balance effect.

Here you can see the difference the color wheels effect can make to a layer, with the original shown first and the color corrected version below it:

Color temperature

Use to warm or cool your layer.

Crush blacks & whites

An alternative to simply altering the contrast, this enables you to change the black and white points separately for finer control.

Curves

Requires the Colorist pack

Curves is a powerful color correction and grading tool, based on an editable graph. Here's an example of the curves graph as soon in the Controls panel:

Curves

The horizontal axis on the graph represents the input, which is the original image. The vertical axis represents the output, which is the graded result. Therefore if you follow a line vertically up from any point on the graph until you hit the curves, then track to the left, you can see how the input is being changed.

Therefore with the default curves graph you can see that the input values are identical to the output values:

Curves original

Two easy presets are provided, one of which resets the graph to the default straight line and another which creates an s-curve:

s-curve

Where the graph becomes steeper you will see increased contrast, whereas a shallower incline will reduce contrast. In the case of an s-curve, the center of the graph is steeper, which increases contrast in the mid-tones, at the expense of detail in the shadows and highlights.

Given that the focus of a frame is often in the mid-tones (such as actor's faces), an s-curve is often an effective way to add perceived detail and contrast to a shot.

Curves can be used to adjust the RGB channels combined or each channel individually. Adjusting individual channels can be useful for correcting white balance and lighting issues.

Exposure

Requires the Starter pack

Simulates the effect of letting more light into the camera lens.

Exposure

Gamma

Individually alter the gamma of red, green and blue channels.

Hotspots

A quick and easy way to isolate the bright areas of your layer.

Hue, saturation & lightness

Control over the hue, saturation and lightness of each color channel.

HSL

Levels histogram

Levels gives you detailed information about the channel composition of the layer. The graph tabs or the sliders can be used to constrain the layer. The histogram is a more accurate way to assess colors than by eye.

Pro skin retouch

Requires the Repair pack

Apply realistic and subtle post-production make-up to your actors, with fine control over skin color, detection thresholds, skin treatment and highlight glow.

Skin retouching has three distinct sections:

Skin Detection, used to define the area to be processed. This area is called the skin matte.
Skin Treatment, for adjusting the amount of processing.
Glow, for adding a subtle glow to the skin area.

The view menu is used to switch between the final result, the skin matte and the source skin in isolation. Switching between these view modes makes it easier to adjust the skin detection settings.

Item

Description

Skin Color

Sets the base color for skin detection. This should be adjusted based on the subject's skin color.

Brightness Threshold

Limits the skin detection based on brightness.

Chroma Threshold

The skin detection is performed in the YUV color space. The chroma threshold defines the distance around the selected color used to create the detection circle.

Softness

Feathers the edge of the skin matte.

Elliptical Deformation

Adjusts the shape of the YUV detection circle into an ellipse, which is a more optimized shape for skin detection.

Blur Selection

Blurs the resulting skin matte.

Smooth

Smoothes the skin by applying a blur.

Edge Threshold

The skin treatment attempts to retain edge detail while smoothing the skin. The edge threshold determines how much detail is retained.

Saturation

Adjusts the color intensity of the skin. A subtle saturation boost often creates a healthy appearance.

Exposure

Easily highlight underlit skin.

Brightness

Strength of the glow.

Threshold

Applies a threshold to the skin. Higher thresholds reduce the amount of skin used to generate the glow.

Radius

Higher radius will create a softer, more diffuse glow.

Colorize

The glow can be influenced towards a specific color.

View

Switch between the final result, the skin matte and the source skin. Note that this view mode will affect final rendering.

White balance

If your video was shot with incorrect white balance, this effect can help to correct the problem. Use the color pipette to select a part of the video that should be white and the layer will be corrected.

In the example below, the white balance has been set to the wall behind the actress. The top image is the original, with an overly warm, yellowish appearance, while the bottom image shows the corrected white balance.
