Getting To Know Motion
Name: Lists the name of the object and its parameters.
Value: Displays the value for the current playhead position for that parameter. You can
drag in the value field to set new keyframe values, or double-click in the field and type
a new value. For more information, see “
Animation menu: The last column contains a pop-up menu to control animation and
keyframing attributes for that parameter. The menu items are listed below.
•
Enable/Disable Animation: Remains dim until keyframing is applied to the channel,
either by using the Record button or by directly adding a keyframe. Once the
channel is animated, the menu item is automatically renamed to Disable Animation.
Activating it at that point hides the keyframes you have set, restoring the parameter
to its default value. However, the keyframes are not thrown away. Choosing Enable
Animation restores the channel to its last keyframed state.
•
Reset Parameter: Removes all keyframes and settings for this parameter. The
parameter value is restored to its default value.
•
Add Keyframe: Adds a keyframe at the current frame. If your playhead is positioned
on a frame where a keyframe has already been added, this menu item is dimmed.
•
Delete Keyframe: Deletes the current keyframe. The Delete keyframe command is
only available if the playhead is positioned on a frame where a keyframe already
exists.
•
Previous Keyframe: Moves the playhead to the previous keyframe for this
parameter. The Previous Keyframe command is only available if a keyframe exists
earlier in the project.
•
Next Keyframe: Moves the playhead to the next keyframe for this parameter. The
Next Keyframe command is only available if a keyframe exists later in the project.
•
Interpolation: Sets the type of curve for the parameter. See the table in the section
called “
” on page 437, for examples of the different interpolation
methods.
•
Before First Keyframe: Defines what happens between the first keyframe and the
beginning of the clip. See “
” on page 441 for examples of the different
extrapolation methods.
•
After Last Keyframe: Defines what happens between the last keyframe and the end
of the clip.
•
Lock/Unlock Parameter: Locks the parameter to prevent changes. When a
parameter is locked, neither keyframes nor curves are adjustable.
•
Reduce Keyframes: Applies a “thinning” algorithm to the keyframes for the selected
parameter. This reduces the number of keyframes in a parameter while attempting to
maintain a similar curve shape.
