Note: Convolution presets are found in the Effects panel’s preset category in a sub-category called “Convolution Kernal.” In this sub-category, there are presets that all have “Convolution Kernal” at the beginning of the name.

1In the Effects panel, click the triangle to expand the Video Effects bin, and then click the triangle to expand the Adjust bin.

2Drag the Convolution Kernel effect to the clip in a Timeline panel.

If the clip is already selected in a Timeline panel, you can drag the Convolution Kernel to the Video Effects section of the Effect Controls panel.

3 In the Effect Controls panel, click the triangle next to Convolution Kernel to expand it.

Each of the settings that start with the letter “M” represents a cell in a 3x3 matrix. For example “M11” represents the cell at row 1, column 1. “M22” represents the cell in the center of the matrix.

4Click on a number next to any of the cell settings.

5Type a value (from –999 to +999) by which you want to multiply that pixel’s brightness value.

6Repeat the last step for all pixels that you want to include in the operation. You don’t need to type values for all of the cell settings.

7Click the number next to Scale, and type the value by which to divide the sum of the brightness values of the pixels included in the calculation.

8Click the number next to Offset, and type the value to be added to the result of the scale calculation.

9Click OK.

The effect is applied to each pixel in the clip, one at a time.

Add Lighting Effects

You can use up to five lights to introduce creative effects. You can control such lighting properties as lighting type, direction, intensity, color, lighting center, and lighting spread. There is also a Bump Layer control for using textures or patterns from other footage to produce special effects such as a 3D-like surface effect. For a video tutorial about using Lighting Effects and the Basic 3D effect, see Creating A Title On A Reflective Surface by Jeff Schell on his Digital Media Net blog.

Note: All Lighting Effects properties except Bump Layer can be animated using keyframes.

You can directly manipulate the Lighting Effects properties in the Program Monitor. Click the Transform icon next to Lighting Effects in the Effect Controls panel to display the adjustment handles and Center circle.

1In the Effects panel, expand the Video Effects bin, expand the Adjust bin, and then drag the Lighting Effects onto a clip in a Timeline panel.

Effects and transitions

If a clip is already selected in a Timeline panel, you can drag the Lighting Effects directly to the Video Effects section of the Effect Controls panel.

2In the Effect Controls panel, click the triangle to expand the Lighting Effects.

3Click the triangle to expand Light 1.

4Choose a light type from the menu to specify the light source:

None Turns off a light.

Directional Shines light from far away so that the light angle doesn’t change—like the sun.

Omni Shines light in all directions from directly above the image—like a light bulb over a piece of paper.

Spotlight Casts an elliptical beam of light.

5 To specify a color for the light, do one of the following:

•Click the color swatch, select a color using the Adobe Color Picker, and then click OK.

•Click the Eyedropper icon and then click anywhere on the computer desktop to select a color.

6(Optional) Click the Transform icon to display the light’s handles and Center circle in the Program Monitor. You can directly manipulate the position, scale, and rotation of a light by dragging its handles and Center circle .

Note: If you have more than one light, Center circles for each light appear in the Program Monitor. Clicking a Center circle displays the handles for a specific light.

7 In the Effect Controls panel, use the following controls to set the properties for the individual source light:

Center Moves the light using X and Y coordinate values for the center of the light. You can also position a light by dragging its Center circle in the Program Monitor.

Major Radius Adjusts the length of an Omni light or Spotlight. You can also drag one of the handles in the Program Monitor.

Projected Radius Adjusts the proximity of a Directional light’s source to the Center circle . A value of 0 positions the light at the Center circle and floods the image with light. A value of 100 moves the light source far from the Center circle, decreasing the light falling on the image. In the Program Monitor, you can also drag the light source point to adjust its distance from the Center circle.

Minor Radius Adjusts the width of a Spotlight. Once the light becomes a circle, increasing the Minor Radius also increases the Major Radius. You can also drag one of the handles in the Program Monitor to adjust this property.

Angle Changes the direction of a Directional light or Spotlight. Adjust this control by specifying a value in degrees. You can also move the pointer outside a handle in the Program Monitor until it turns into a double-headed curved arrow , and then drag to rotate the light.

Intensity Controls whether a light is bright or less intense.

Focus Adjusts the size of the Spotlight’s brightest area.

Important: The Light Type determines which Lighting Effects properties are available. Make sure to click the Transform icon to display a light’s handles and Center circle in the Program Monitor.

8 Use the following controls to set the Lighting Effects properties:

Ambient Light Color Changes the color of the ambient light.

Ambience Intensity Diffuses the light as if it were combined with other light in a room, such as sunlight or fluorescent light. Choose a value of 100 to use only the light source, or a value of –100 to remove the light source. To change the color of the ambient light, click the color box and use the color picker that appears.
