•
Height: A slider that sets the height of the generator, in pixels. Values range from 1 to the
height of your project.
•
Pixel Aspect Ratio: A pop-up menu that sets the aspect ratio of the pixels drawn by the
generator. Values can be selected from the following menu 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 (960 x 720, 1440 x 1080), HD (1280 x 1080), or Custom. When a value
other than Custom is selected, the Pixel Aspect Ratio of that selection appears 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.
Controls in the HUD
In general, Generator HUDs contain a subset of the larger group of controls located in the
Generator 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 Inspector. This slider sets the transparency of the generator as a whole. Several
generators contain a separate opacity control in the Generator Inspector, which is independent
of the like-named control in the Properties Inspector.
Image generators
Image generators overview
Image generators quickly add animated or static graphics, such as stars, swirls, rays of color, or
lens flares to a project. The image generator category is labeled Generators in the Library.
For a description of each of the Image Generators, see the list in the Help table of contents (the
sidebar to the left of this window).
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.

Parameters in the Inspector
•
Size: A slider that sets the size of the shapes and spaces in the pattern.
•
Speed: A slider that sets the speed of movement of the light patterns.
•
Refraction: A slider that sets the refraction of the light shapes.
•
Brightness: A slider that sets the brightness of the light shapes.
