Adding PiP Effects With Predefined Motion
To add a predefined motion to a PiP effect, click on the motion tab to display the
PiP motion options and then select a predefined motion from the available list.
Customizing PiP Effect Motion
The PiP Designer uses keyframes to customize the motion on a PiP effect (and
transparency if required). Keyframes are frames of your video that define the start
and end points of an effect, which in this example is motion or transparency.
Note:
some objects have predefined motion already applied.
To customize the motion of a PiP effect:
•
drag an existing keyframe to a new location in the preview window. The PiP
effect will move along the new path to get to the changed keyframe.
•
drag the path line to alter the path the PiP effect will take to get to the next
keyframe.
•
click the add keyframe button to add a new keyframe where required.
•
click on to duplicate the previous or next keyframe on the keyframe
timeline. Doing this will copy the properties of the indicated keyframe to the
new position.
Customizing the Speed of PiP Effect Motion
You have full control over the speed to the PiP effect’s motion. The following three
factors determine the speed of the PiP effect’s motion.
Duration of the PiP clip in the timeline
The longer the PiP clip, the slower the PiP object’s motion will be. For example, if
the PiP clip is 10 seconds, it will take the PiP effect 10 seconds to complete the
applied motion.
