Tracking position (PB only)
When you track position, you are attaching a layer or an effect to a single point. The attached layer floats over (or under) the tracked point and is not distorted or skewed to simulate perspective. For perspective, use perspective corner pinning. For more information, see Tracking position using perspective corner pinning (PB only).
To define tracking regions for position: - Size the feature region to include only the object you are tracking.
- Size the search region to accommodate the movement you are tracking. If the motion is jumpy and sudden in one or more directions, stretch the search region in those directions, so that the Tracker/Stabilizer can accurately find and match the suddenly shifting pixels. If motion is smooth in all directions, you can size the search region to be just outside the feature region, to minimize tracking time.
- Drag the track point anywhere within the layer. If you want to attach the second layer directly on top of the feature region, place the track point in the center of the feature region. If you find that the second layer is not positioned correctly during tracking, you can stop the track and adjust the track point by dragging it and, if necessary, monitoring the tracking coordinates (for details on the tracking coordinates, see Working with the Tracker/Stabilizer Controls (PB only)). After you apply the tracking to the second layer, you can also adjust the layer's anchor point to reposition it.
