Animation Considerations
This section provides more
information on creating animations.
These topics can give you ideas about
how to work with animation files.
Color
You might want to create a color set for
the animation. Creating a color set
helps you better control the use of
color. For example, you wouldn’t want
the colors of your characters shifting
between frames. Using a particular
color set prevents this from
happening.
Not all colors are video legal. For
information about converting colors
for use in video, refer to “Video Legal
Colors” on page 273. For more
information about using color, refer to
“Working with Color” on page 77.
You might want to set up an image of
each character with annotations to
specify which colors to use in which
areas.
Frame Rate—A Matter of
Time
Frame rate describes the number of
image frames displayed per second
(fps). The frame rate can determine
not only how big a file your animation
is, but also how smooth the motion
appears.
When you save a movie as a
QuickTime or AVI file, you can
specify the rate of display. This doesn’t
necessarily mean that what you
specify is what you’ll experience.
Factors like frame size, compression
method, and computer speed can
prevent some movies from achieving
their set rate.
If your animations are going no
farther than the computer, frame rates
of 8, 10, and 12 fps are good choices.
If you intend to create your work for
NTSC video, 15 fps is a good choice.
If you’re less concerned with quality,
you might use 10 fps.
• The frame rate of film is 24 fps.
• The frame rate of NTSC video is
30 fps (29.97 fps in broadcast
