Chapter 18 Generators 736
In a File generator, each line of text appears onscreen, holds for a moment, and then disappears
before the next line appears. You can control how the text appears using the controls in the
Inspector. The duration of the generator bar in the Timeline determines how long it takes for all
lines of text in the source file to reveal themselves.
Parameters in the Inspector
•
Browse: A button that opens a browser window where you can select the plain text (TXT) file
to use as the text source.
•
Speed: A pop-up menu that sets the behavior of the text as it appears and disappears
onscreen. Choose any of several options:
•
Constant: The text appears and disappears at a steady speed from the first word or line to
the last word or line in the text file.
•
Ease In: The text appears at a slow speed.
•
Ease Out: The text disappears at a slow speed.
•
Ease Both: The text appears and disappears at a slow speed.
•
Accelerate: The text appears and disappears with increasing speed.
•
Decelerate: The text appears and disappears with decreasing speed.
•
Custom: Defines the speed of appearance and disappearance of the text by setting
keyframes for the text from 0 to 100 percent using the Custom Speed slider, described
below. In other words, you determine the rate of the appearance and disappearance of the
text over time.
•
Custom Speed: A slider, available when Custom is chosen from the Speed pop-up menu, that
lets you keyframe the timing of the appearance or disappearance of the text. At 0 percent,
none of the text has appeared; at 100 percent, the last of the text in the file is displayed (the
last line or word).
•
Random: A checkbox that, when selected, randomizes the order in which the lines of
text appear.
•
Random Seed: Controls that let you change the seed number (by typing a new number in the
text field or clicking Generate). This changes the random calculations to display the text in a
different order.
Numbers
The Numbers text generator displays random numbers based on settings in the Inspector.
Parameters in the Inspector
•
Animate: A checkbox that, when selected, enables animation of the numbers as the project
plays. When deselected, a static number is displayed.
•
Start: A slider that sets the beginning number for the generator. Slider values range from 0 to
100. For negative numbers or numbers greater than 100, use the value slider (to the right of
the slider). Default values are based on the project. For example, when the Numbers generator
is added to a default project of 300 frames, the Start value is 1 and the End value is 300.
