Working with Effects

This group of values is used to reduce or strengthen the color intensity within the ranges of colors with the primary red, green and blue.

There are 3 scales on top: red to cyan, green to magenta and blue to yellow. If you click the mouse on the values and drag to the right, the colors get closer to red, green and blue, if you drag to the left, the colors become closer to cyan, magenta and yellow correspondingly. According to the scale of black to white on the left the values of the upper cells are used for lights, the middle cells are used for midtones, and the bottom cells – for shadows of the image. To set color balance you also can double-click the cell and enter the value via the keyboard. Alternatively, use the arrow up to add and arrow down to subtract the values (pressing the button once equals one point). Hit "Enter" to save the changed value and exit the keyboard control mode.

Min. value is -100.0; max. value is 100.0.

Select the "Preserve lightness" checkbox to save the original lightness of the image.

This tool is used for replacing colors of the video clip with different ones and is useful for setting lights and shadows of the image.

The cells from the "Source" column contain colors to be replaced; the ones from the "Target" column define the colors to be used instead. The gray scale indicates that the top cells match the tones for lights, the middle cells match the midtones, and the bottom cells are used to correct shadows.

There are two ways to choose colors for matching. Click on the cell with color and select the desired color in the standard "Color" window that appears:

You also can use the color picker tool. Press the "Dropper" button and when the mouse cursor turns into a dropper you can click on any color on the monitor screen to pick it for matching. The cursor will change back into regular when you pick a color.

Select the "Preserve lightness" checkbox if you need to maintain original lightness of the image.

It is possible to adjust contrast, brightness, gamma, hue and saturation of the image.

The values in column "Master" indicate the full color signal and adjust color for the whole image. Enter the values via keyboard or use the mouse to change them – drag to the right to make the values higher, drag to the left to reduce the values:

You can also adjust contrast, brightness and gamma for RGB components separately in the cells of the corresponding columns.

Min. value for contrast, brightness and saturation is -100.0, max. is 100.0; the range of values for gamma is from 0.1 to 3.0; the value of hue is adjustable from -180.0 to 180.0.

In this section you can replace colors of the clip by adding tint and setting the white color balance.

The following color controls are available in the HSL tab:

Move the scroll of the HSL controls to adjust the brightness, contrast, saturation and hue parameters of the current clip. All introduced changes are displayed instantly in preview.

Here you can adjust black and white limits for the clip:

The "Invert chroma" option inverts the chromacity value of every pixel in the clip.

The "Invert luma" option reverses the brightness level of every pixel in the clip.

Once you render an effect, you can see the result directly in preview:

or view the modified clip on Timeline or in Sequence Viewer.

Enable the border parameters by selecting the "Enabled" checkbox.

The "Border" tab provides a group of controls for the foreground video border:

Once you render an effect, you can view the result in Sequence Viewer:

At first define the colors you need to make transparent by clicking on the cell and launching the standard "Color" window or using color picker. If the background consists only of one color, select it in the "Lights" cell. If there are two color tones in the background, select the "Shadows" checkbox and select the necessary color in the cell.

Tolerance value defines the amount of pixels for the area of complete transparency.

If the "Show mask" checkbox is selected, the transparency mask for the selected colors will be shown. The visible colors are displayed in white; the black color replaces transparent areas; the semitransparent pixels are shown in gray colors.

In this section define the transparency values:

Fuzzy edge value is used to define semitransparent areas. The zero value means that all the colors are completely visible, higher values add transparency thus smoothing down the border lines.

Dissolve details value is used to dissolve transition of the foreground video details according to the defined Fade In/Out values to a Chroma Key.

Fill holes value is used to add solidity to regions of marginal transparency within Chroma Key. The zero value means that all margins are completely visible and solid, higher values smooth down the lines.

Gamma value is used to correct luminance and optimize perceptual performance.

In this section you can deal with the colors, that are left visible after transparency settings have been applied.

The grey threshold value indicates the amount of grey color that replaces the semitransparent pixels; the higher the value, the more pixels will be replaced by grey color.

The edge de-saturation value is set to 100.0 by default which means that the semitransparent colors are grey according to the "Grey threshold" value. Reducing the value of this field makes these colors darker; the zero value turns them into black.

In the given clip the mask of an image with transparency applied to the range of light and dark green colors looks as follows:

To remove the effect select it and hit the "Delete" key or choose the "Remove" command from the context menu.
