Stretch Matte To Fit Scales the selected clip to match the size of the current clip. If Stretch Matte to Fit is deselected,

the clip designated as the matte is centered in the first clip.

Composite Matte With Original Composites the new matte with the current clip, rather than replacing it. The resulting

matte lets the image show through only where the current matte and the new matte both have some opacity.

Premultiply Matte Layer Premultiplies the new matte with the current clip.

Solid Composite effect (Windows only)

The Solid Composite effect offers a quick way to create a composite of a solid color behind the original source clip. You

can control the opacity of the source clip, control the opacity of the solid, and apply blend modes all within the effect’s

controls.

Source Opacity The opacity of the source clip.

Color The color of the solid.

Opacity The opacity of the solid.

Blending Mode The blending mode used to combine the clip and the solid color.

Color Correction effects

Jeff Sengstack provides an overview of color correction and enhancement on the Videomaker Magazine website.

Brightness & Contrast effect

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

that no change is made. Using the Brightness & Contrast effect is the easiest way to make simple adjustments to the

tonal range of the image. It adjusts all pixel values in the image at once—highlights, shadows, and midtones.

Broadcast Colors effect

The Broadcast Colors effect alters pixel color values to keep signal amplitudes within the range allowed for broadcast

television.

Use the Key Out Unsafe and Key Out Safe settings for How To Make Color Safe to determine which portions of the

image are affected by the Broadcast Colors effect at the current settings.

Broadcast Locale The broadcast standard for your intended output. NTSC (National Television Standards

Committee) is the North American standard and is also used in Japan. PAL (Phase Alternating Line) is used in most

of Western Europe and South America.

How To Make Color Safe How to reduce signal amplitude:

• Reduce Luminance Reduces a pixel’s brightness by moving it toward black. This setting is the default.
