โMake a Tracker Stationary
Once in a blue moon, someone wants a tracker that remains stationary throughout a shot. You can do that like this:
for each frame, make tracker 1's key location its location on frame 0 and retrack it.
The retrack the tracker part is needed to update the final tracking results; otherwise you'd have to hit Play to run through the shot to see the result.
You can make this into a handy procedure:
define the procedure to freeze a tracker. unlock the tracker.
for each frame, make the tracker's key location its location on frame 0 and retrack it.
lock the tracker. done.
define freeze is a verb.
