Click on the Motion tab to add motion* to media clips, allowing them to move across the screen. You can choose from a number of predefined motion paths or create your own custom motion. You can also add a rotation effect to the media clips.

Using a Motion Path Template

To add motion to media clips you can select a motion path template on the Motion tab that fits your requirements. Note that keyframes are added to the Position track of the PiP Designer keyframe timeline. These motion path templates have predefined motion in them, but you can customize the motion. See Customizing PiP Motion and Utilizing PiP Keyframes for detailed information on using keyframes to customize motion.

Customizing Motion

The PiP Designer uses keyframes to customize the motion of media clips. Keyframes are frames of your video that define the start and end points of an effect, which in this example is motion.

To customize the motion of media clips:

•drag an existing keyframe to a new location in the preview window. The media clip will follow the modified path to get to the changed keyframe position.

•drag the path line to alter the path the media clip takes to get to the next keyframe.

•use the player controls to find a position on the motion path, and then click on the Position track of the keyframe timeline to add a new keyframe at a new position, if required.

Customizing the Speed of Media Clip Motion

You have full control over the speed to the media clip's motion.

The following three factors determine the speed of the media clip's motion.

Duration of the Media Clip in the Timeline

The longer the duration of a media clip, the slower its motion is. For example, if the media clip is 10 seconds, it will take the clip 10 seconds to travel from the first Position keyframe to the last Position keyframe.

Distance Between Keyframes

The distance between each keyframe also contributes to the speed of the media clip motion. The further the distance between each keyframe, the quicker the media clip needs to move to get to the next keyframe.

Keyframe Timeline

The keyframe timeline is located below the preview window. Each keyframe in the motion path has a corresponding marker on the keyframe timeline.

If the media clip on the timeline has a duration of 10 seconds, the keyframe timeline is 10 seconds long. To increase the speed of a media clip's motion, drag a keyframe marker closer to previous keyframe marker.

Saving a Custom PiP Motion Path

Once you finish modifying your PiP motion path you can save it for future use. To save a motion path, click on to save it as a custom path. It is then available in motion path list the next time you want to use it.

Customizing Media Clip Rotation

Select the Rotation Settings option to customize the rotation of moving media clips. Use the slider to set the amount the media clip will rotate as it moves across the screen. Select whether the media clip rotates counter clockwise, or clockwise.

Applying Motion Blur

Select the Motion blur* option to make media clip movement appear smoother, giving it a more natural and authentic look.

Once selected, use the available sliders as follows:

•Blur length: drag this slider to set the duration (number of frames) you want blended into a single frame (the blur). Dragging the slider right will apply more of a blur to the moving media clip.

•Blur density: drag this slider to set the number of samples (of the media clip) used per frame. Dragging the slider right will make the media clip less blurry as it adds samples to fill the missing content caused by the movement.
