Attach to picture position in the video
You can attach a video, picture or text object to moved picture content of
another video. The attached object automatically completes the movement of a
picture element from the film, making it appear magnetic. For example, you
could use this method to insert a hat that stays on someone's head
throughout, even if the person hops through the picture.
Let's roll:
 Place an overlay object (e.g. a photo of a hat) on a track below a video with a
moving image element (e.g. a walking person).
 Right click the object and select the "Attach to picture position in the video"
movie point.
 Then click "Continue" in the dialog that appears.
Note: If you want to attach two objects, e.g. a title and a speech bubble, an
additional dialog appears, which lets you select the objects you want to attach
to your video.
 The next dialog asks you to draw a frame around the image content to be
tracked. The content should have high contrast to its background.
 Movement will be automatically calculated and a series of keyframes that
control the position and size of the effect according to your wishes will be
generated.
Image stabilization
The motion stabilizer reduces unsteady camera motion and helps to smooth
pans. This option can be accessed from the context menu of a video object or
the "Effects" menu > "Open video objects".
Functionality
Image stabilization balances undesired picture movements. The motion
stabilizer equalizes inadvertent movements in the image by moving the image
in the opposite direction in accordance with the wrong movements. This
produces unusable edges in the footage that are cut off automatically, and
black strips, which are then removed using a zoom shot. The result: A clearly
more stable, almost imperceptibly larger picture.
