In this lesson, you work
with a scene we’ve created for your use. In the following steps,
you open the scene and set how long the animation will play.
To open the scene
- Make sure to do the steps in
Preparing for the lessons.
- Open the scene file named Keyframing.mb.
This file can be found
in the GettingStarted directory
that you set as your Maya project.
The scene contains a
ball object that is currently positioned on the X-axis near the
edge of a ground plane.
To animate the ball,
you key its position at different times of the playback range.
The playback range is
defined by the Time and Range slider. The Time and Range slider
controls allow you to playback or scroll through your animation
or move to a specific point in time of your animation so you can
To set the playback range for the scene
- Look over the playback controls, as shown
in the figure below:
The Time Slider displays the playback range and
keys you’ve set for a selected object. Keys are displayed as red
lines. The box at the right of the Time Slider lets you set the
current frame (time) of the animation.
Playback Controls control animation playback. You may recognize the
conventional buttons for play and rewind (return to the start time). The
stop button appears only when the animation is playing. To find
out which operation a button represents, hold the mouse pointer
The Animation Preferences button
displays a window for setting animation preference settings such
as the playback speed.
The Range Slider controls the range of frames
that play when you click the play button.
The above items will
have more relevance as you work through this lesson. After you complete
this lesson, experiment with these items to learn more what they
The playback range is
currently set at a range of 1 to 24. At a default playback rate
of 24 frames per second, the scene can play for one second. Because
you’ll animate the ball for a few more seconds than this, you need to
lengthen the playback range.
the Playback End Time box, enter
A frame rate of 24 frames
per second (fps) is the frame rate used for motion picture film.
For video, the frame rate can be 30 fps (NTSC) or 25 fps (PAL) depending
on the format being used.
With a playback range
of 1 to 72, you’ll be able to create three seconds of animation.
(72 frames divided by 24 frames per second = 3 seconds.) This is
enough time for the short animation you’ll create in this lesson.
