92 Chapter 2 Motion Tracking
When a track is lost during an analysis, Motion automatically jumps back to the frame
at which the track failed. The “bad” track point is identified by an “x” in the Canvas.
You can use the bad track point, or use any point prior to the failed track frame, to
move the tracker and select a new reference feature. In the Canvas, the track point at
the current playhead position is emphasized.
2 Turn on the Offset Track button in the HUD or Behaviors tab of the Inspector.
The track point at the current playhead is highlighted.
