Animating scene objects
Keyframe Editor
The Keyframe Editor (figure 7-3 ) is located above the Animation Editor’s timeline, and
allows you to set the parameters for the selected keyframe on a property channel. A
keyframe represents a particular point of change in time of the object property's setting.
Since the parameters differ depending on the type and function of the property, the
Keyframe Editor’s contents change according to the selected keyframe. In particular, the
VALUE ENTRY FIELD changes depending on the property displayed. For example, figure 7-3
demonstrates that setting a keyframe for the O PACITY property involves editing a value
displayed in a text box, while the V ISIBLE property involves selecting or clearing a check box
that represents either O N or O FF .
Figure 7-3. Use the Keyframe Editor to specify the selected keyframe’s settings
The following table provides a functional description of each of the Keyframe Editor’s fields.
In addition, The acceptable values and settings for the different property values is described
in
“Animated property descriptions” on page 7-40 .
Name The N AME field allows you to enter a name for the selected keyframe.
A name is required only if the keyframe will be accessed using a S ET K EY F RAME
action (see page 10-40 ).
Keyframe names should be unique within an animation. For example, you cannot
make an action execute on two keyframes simultaneously by giving them the same
name.
Frame Displays the keyframe’s location on the timeline either as a frame number or as
timecode. The relation between frame number and time comes from the Video
Format property of the scene. For instance, if the NTSC format is chosen, there are
30 frames per second.
As demonstrated by the images below, you can toggle back and forth between
F
RAME and T IME when assigning keyframes by right-clicking on F RAME or T IME field,
then selecting or deselecting F RAMES from the context menu.
