Generator Parameters

The following sections describe the common parameters and details of each generator.

Parameters in Common

All generators have a reset button and Width, Height, and Pixel Aspect Ratio controls, which are located in the Generator tab of the Inspector. The controls specific to each type of generator are discussed later in this chapter.

  • Reset: Click to reset the generator to the default settings.
    Figure. Inspector showing reset button.
  • Width: Sets the width of the generator, in pixels. Values range from 1 to the width of your project.
  • Height: Sets the height of the generator, in pixels. Values range from 1 to the height of your project.
  • Pixel Aspect Ratio: Sets the aspect ratio of the pixels drawn by the generator. Values can be selected from the following options: Square, NTSC D1/DV, NTSC D1/DV Anamorphic, PAL D1/DV, PAL D1/DV Anamorphic, Anamorphic 2:1, D4/D16, D4/D16 Anamorphic, HD (960x720, 1440x1080) HD (1280x1080), or Custom. When a value other than Custom is selected, the Pixel Aspect Ratio of that selection is displayed in a value field next to the pop-up menu. Enter values from 0 to 10000 in the value field. If the value does not correspond to a preset value (for example, 2 for Anamorphic 2:1), Custom appears in the pop-up menu.

HUD Controls

In most cases, the HUD controls for each generator are identical to the generator’s controls in the Inspector. Additionally, the HUDs contain the Opacity and Blend Mode parameters.

Important: The Opacity parameter in the HUD is identical to the Opacity control located in the Properties tab. This sets the transparency of the generator as a whole. Several generators contain a separate opacity control in the Generator tab of the Inspector, which is independent of the Properties tab.

Caustics

The Caustics generator creates an animated, simulated water surface. The size, speed, refraction, brightness, and color of the Caustics pattern can be modified and animated. You can use the Caustics generator to add light patterns to a project, or as the source object for an image map.

Figure. Canvas window showing the Color Solid generator with a variety of settings.

Note: When you want to create and animate a small, color-filled box or shape, use the Shape tools to draw a vector-based shape rather than creating and masking a color solid. This is more efficient in terms of processor time and workflow.

Parameters in the Inspector
  • Color: Sets the color. Use the disclosure triangle to display Red, Green, and Blue sliders for more precise color selection.
HUD Controls

The HUD contains the following control: Color.

Concentric Shapes

The Concentric Shapes generator creates a repeating pattern of shapes.

Figure. Canvas showing examples of the Concentric Shapes generator.

Noise

Where would motion graphics artists be without a noise filter or generator? To make animated noise, you can keyframe the Random Seed parameter in the Noise HUD or Inspector. When filters are applied to an animated Noise generator, you can create some unique textures. In the second image below, the Scrape distortion filter is applied to an animated Noise generator to create a vibrant, electric light-type texture.

Figure. Canvas window showing the Noise generator alone, and combined with a Scrape filter.
Parameters in the Inspector
  • Random Seed: Each seed value gives you a different noise image, so changing this over time allows you to get constantly changing noise. The easiest way to see and use the random seed parameter is to add a ramp behavior to it, then ramp from a very small random seed value to a very large random seed value over time.
HUD Controls

The HUD contains the following control: Random Seed.

One Color Ray

The One Color Ray generator creates a ray pattern based on variations of a color. You can select the color, the degree of variance, the number of divisions represented, and rotation of the pattern.
