Motion Tracking
Avid FX provides sophisticated tools to track or follow motion in an video or image
sequence. There are three effects or filters to assist you: Corner Pin Tracker, Motion
Stabilizer, and Motion Tracker.

Generating the Motion Path
You can generate motion path data by estimating the motion of an object in a media file. You
can then use this data to control the motion of another aspect of the effect. For example, use
the Motion Tracker to create an effect in which text or a spline object follows a moving
object in a media file. You can also use Tracker data with filters, allowing you to cause
applied lights, blur, or other filters to follow an object.
n
The field order of the media you are using must match the field order setting in the in the
Import tab in the Preferences window.
If the media that you want to track is a different size than your Project size, you must load
the media into a Shape track and then drag the Shape track into the Motion Filter’s Source
track.
