    Moving Footage And Not Moving Mask

      i have a mask on some footage, complex, basically a sky replacement shot-
      i would like to then track the motion of the camera on original footage then apply those points to a null, and parent my replaced sky to null.

      problem is is then moves the mask on the footage too.... i would like the mask to remain independant of the footage even though mask has to be on that footage...

      i am masking the sky rather than footage as i am just importing the replaced clouds as an alpha back over my original footage as an alpha.

      suggestions / other techniques?
