  I try to edit a video clip, like a steady cam and slow motion, using a mask and Time Warp in after effect.
  
  But, whenever i select any effect in Effect menu of a menu bar, the mask is not working.
  
  Can i use a mask and effect at the same time?
  
  or, i have to use pre-composition where effect is applied, and then mask, such pre-comp?
  
  plz help me.
