USING ADOBE PREMIERE PRO 393 Effects and transitions To render the shadow without the image, select Shadow Only. Note: Because Drop Shadow works best when it's the last effect rendered, apply this effect after applying all other effects. You can create a more realistic-looking shadow on animated clips by applying and animating the Motion or Basic 3D effect prior to applying Drop Shadow instead of animating the Fixed Motion effect because Fixed effects are rendered after Standard effects. More Help topics "Select a color with the Adobe Color Picker" on page 321 Radial Shadow effect The Radial Shadow effect creates a shadow from a point light source over the clip it's applied to, rather than from an infinite light source (as with the Drop Shadow effect). The shadow is cast from the alpha channel of the source clip, allowing the color of that clip to influence the color of the shadow as light passes through semitransparent areas. Original (left), and with effect applied (right) Shadow Color The color of the shadow. Note: The colors of the clip may override the Shadow Color if you choose Glass Edges from the Render control menu. See the Render and Color Influence controls for more information. Opacity The opacity of the shadow. Light Source The location of the point light source. Copy and paste position keyframes from another effect (for example, Lens Flare) to quickly create a shadow that matches the other effect's light source. Projection Distance The distance from the clip to the surface on which the shadow falls. The shadow appears larger as this value increases. Softness The softness of the shadow's edges. 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 Last updated 1/16/2012
