When footage was shot with a wide angle lens you should use optics compensat=
ion to remove the lens distortion before you do the camera track. Then comp a=
gainst the plate with the distortion removed and you can reintroduce the len=
sing by reversing the optics compensation and applying that over the comp as=
 an adjustment layer
