Move a segment of the animation path
m Drag the path segment between the two selected keyframes.
Note: You can also Shift-select the keyframes that bound the path segment or segments you
want to move, then drag one of the selected keyframes (or the segment between two adjacent
keyframes).
Select an adjacent keyframe on the animation path
m Click the path segment immediately to the right or to the left of a selected keyframe.
The adjacent keyframe is selected. Drag the path segment between the two selected keyframes
to move the segment.
Animate via the HUD
Parameters that appear in the HUD can be keyframed using the Record button or by setting an
initial keyframe. Using this technique, you can animate basic object properties such as opacity or
position, or create advanced effects such as setting static filters into motion. In this example, the
HUD is used to animate an object’s opacity.
Animate a clip’s opacity via the HUD
1 Place the playhead where you want to begin the fade.
2 Do one of the following:
•
Click the Record button (or press A) to turn on keyframe recording, then click the Opacity
slider handle in the HUD.
Even if you don’t change the slider’s value, clicking it sets an Opacity keyframe at that point.
This way, the object remains at its previous opacity from the beginning of the clip until that
keyframe, then begins the interpolation toward the next keyframe.
•
With the Record button off, click the Opacity slider handle in the HUD, then press Control-K.
3 Move the playhead forward to a new time.
4 Change the Opacity value.
5 Move the playhead forward again.
6 Change the Opacity slider again.
7 If keyframe recording is on, click the Record button (or press A) to turn off keyframe recording.
