Apple Final Cut Pro 7 - Manual (Page 1250)

Some generators, such as the Slug, Matte, and Particle Noise generators, fill the entire
frame size of your sequence. Others, like the text filters, are created with an alpha channel
that allows your text to be quickly superimposed against an image, or against black. (See
“Creating Titles” for information about text generators.)
Generators can have filters and motion settings applied to them. For example, you can
use a Color Matte filter in conjunction with a Garbage Matte or Mask Shape filter to quickly
create a clip consisting of a shape against a transparent background. The transparent
background exists because an alpha channel has been added to the Color Matte filter.
For more information on using Matte and Mask filters, see
“Keying, Mattes, and Masks.”
The parameters of some generators can be keyframed to change their appearance over
time. You add keyframes to generators in the same way you add keyframes to motion
settings and filters. For more information about how to create keyframed effects in
Final Cut Pro, see
“Animating Motion Effects Using Keyframes.”
Video and Audio Generators Available in Final Cut Pro
Final Cut Pro supports both FXScript and FxPlug generators. The following tables explain
the generators available in Final Cut Pro.
Color Bars, Tone, and Other Signal Generators
You use color bar and signal generators for calibration and testing purposes. Each Bars
and Tone generator uses the image dimensions and color space intended for a particular
video system. For more information, see
“Measuring and Setting Video Levels.”
