I have veirticle black bars on each side of a still when it is placed on the time line.  I have zoomed in using the Pan/ crop tool to get rid of these bars but no luck. I am trying to start in close and zoom out and even when zoomed in on jus 20% of the photo I still get the bars in the Vieo Preview window.  4 other stills from same shoot and camera are not having this problem ??  The project is HD  with resulting poixel aspect ratio of 1,333.   In the Event Pan/Crop window the dashed line that sets the picture zoom limits is well with in  the picture on all sides...???
  Any thoguhts ??   K
