Effects and transitions

Last updated 11/6/2011

Render The type of shadow:

• Regular Creates a shadow based on the Shadow Color and Opacity values, regardless of semitransparent pixels in

the clip. (If Regular is chosen, the Color Influence control is disabled.)

• Glass Edge Creates a colored shadow based on the color and opacity of the clip. If the clip contains semitransparent

pixels, the shadow uses both the color and transparency of the clip, creating the appearance, for example, of sun

shining through stained glass.

The more transparent the pixels in the clip are, the closer the shadow color matches the colors of the clip. If the clip

contains no semitransparent pixels, Glass Edge has little result.

Note: Anti-aliased edges produce colors in a shadow edge if you choose Glass Edge, even if the clip is fully opaque. The

clip’s colors shine through these anti-aliased edges, and the Shadow Color fills the center of the shadow.

Color Influence The fraction of the clip’s color values that appear in the shadow. At 100%, the shadow takes on the

color of any semitransparent pixels in the clip. If the clip contains no semitransparent pixels, Color Influence has little

result, and the Shadow Color value determines the shadow’s color. Decreasing the Color Influence value blends the

colors of the clip in the shadow with the Shadow Color. Increasing Color Influence reduces the influence of the Shadow

Color.

Shadow Only Select to render only the shadow.

Resize Layer Select to allow the shadow to extend beyond the clip’s original boundaries.

Stylize effects

Alpha Glow effect

The Alpha Glow effect adds color around the edges of a masked alpha channel. You can have a single color either fade

out or change to a second color as it moves away from the edge.

Glow Controls how far the color extends from the alpha channel edge. Higher settings produce larger glows (and can

cause very slow processing before playback or export).

Brightness Controls the initial opacity of the glow.

Start Color Shows the current glow color. Click the swatch to choose another color.
