Clouds
The Clouds generator creates an animated cloud pattern. You can modify or animate
the color, scale, speed, and strength of the cloud layers.
Parameters in the Inspector
The following section describes the Clouds generator controls, which are located in the
Generator tab of the Inspector.
Width: Sets the width of the Clouds generator, in pixels. Values range from 1 to the
width of your project.
Height: Sets the height of the Clouds generator, in pixels. Values range from 1 to the
height of your project.
Note: Although the sliders in the Inspector are usually limited to the maximum values
of Width and Height as set in your project, you can often manually enter values outside
of those ranges in the value fields.
Pixel Aspect Ratio: Sets the aspect ratio of the pixels drawn by the generator. Values
can be selected from the following: Square, NTSC D1/DV, NTSC D1/DV Anamorphic,
PAL D1/DV, PAL D1/DV Anamorphic, Anamorphic 2:1, D4/D16, D4/D16 Anamorphic,
DVCPro HD 720p/1080i5, DVCPro HD 1080i60, 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, and Custom
appears in the pop-up menu.
Scale: Gives the appearance of zooming in or out of the simulation by scaling the
generator. Larger numbers indicate a higher level of zoom. The default slider values
range from 8 to 64.
Speed: Sets the speed of movement of the clouds. Values range from 0 to 2.
Gradient: Sets the color gradient used for the clouds. For information on using
gradients, see “
Using the Gradient Editor” on page 485.
