Blender tracking rendered image perspective skewed

Support Compositing and Post Processing

Hi all, 1st post here,
I have been tracking some footage and all has been going well, and the tracked objects match up perfectly to the background image in the view-port when looking through the camera, HOWEVER, when I actually render the image out the background image now seems offset and scaled. Any tips on how to rectify this issue?

Connect Distort/Scale node (set it to "Render Size) between Image and Alpha Over.
