  <p>The problem is:</p>

ThreadText: # After Effects: Apply motion tracking to a scaled layer
  
  (Asked by: username_0 on 2015-02-08)
  
  After effects 10.5 (CS 5.5)
  
  I have two clips
  
  * a layer with a smoke wisp curling up, much bigger than it will appear
  * a layer with some slightly shaky footage of a broken machine just sitting there
  
  I want to make the smoke wisp curl up from the machine, scaled to the footage.
  
  The current set up:
  
  * the footage with the machine is the main footage
  * I've made a Tracker in that layer tracking the machine… the positions look right
  * the Tracker targets the smoke
  
  The problem is:
  
  * if the smoke clip is scaled properly, the tracking motion on the smoke is not visible
  * I discovered this is because the tracking is applied before the scale - so the differences in position become tiny
  
  I speculate a solution might involve having the Tracking information applied to the smoke layer AFTER it's been scaled.
  
  QUESTION(s):
  
  1. how do I get the Tracking information applied to the smoke layer
     AFTER it's been scaled?
  2. …or am I doing this wrong? If so, how would I achieve this effect?
