Analyse the clip backward
            when the pattern you want to track grows larger or when it is off
            screen at the beginning of the clip.
         
         NoteYou cannot analyse
               backward if you need to change or snap the reference. In this case,
               reverse the clip without interpolation before entering the Stabilizer
               and analyse it forward.
            
          
         To analyse backward:
         
         
            - Select Backward from the Direction box.
            
 
            - Go to the last frame of the sequence.
            
 
            - Position the reference and tracker boxes.
