Tracking paths
Corel VideoStudio lets you track specific points or areas to create a moving path. This path
represents the location of the selected point or area within the sequence of video frames.
Once you have tracking paths, you can choose to add matched objects around the tracker
area or blur video elements using the tracker.
This section contains the following topics:
• Adjusting tracking paths
• Using objects on tracking paths
• Using the Path Library
Adjusting tracking paths
You can fine-tune or modify the behavior of a tracking path by manually resetting track
points. For more information on creating tracking paths, see “Tracking motion of video
objects” on page 159.
