Tracker Inspector controls, with the tracking
analysis buttons at top, the tracker options in
the middle, and the Tracker List below.
Additional controls over each tracker and the image channels being analyzed appear at the
bottom, along with offset controls for each tracker, but we don’t need those now (at
least not yet).
Again, this track is so simple that we don’t need to change the default behaviors that much, but
because the drone is flying in a circular pattern, the shape of the pattern area is changing as
the clip plays. Fortunately, we can choose Every Frame from the Adaptive Mode menu to
instruct the tracker to update the pattern being matched at every frame of the analysis, to
account for this.
Changing the Adaptive Mode of the Tracker node to Every
Frame to account for the camera’s shift of perspective.
Now, we just need to use the tracker analysis buttons at the top to begin the analysis. These
buttons work like transport controls, letting you start and stop analysis as necessary to deal
with problem tracks in various ways. Keep in mind that the first and last buttons, Track from Last
Frame and Track from First Frame, always begin a track at the last or first frame of the
composition, regardless of the playhead’s current position, so make sure you’ve placed your
tracker onscreen controls appropriately at the last or first frame.
The analysis buttons, left to right: Track from Last Frame, Track
Backward, Stop Tracking, Track Forward, Track from First Frame.
