I'm having problems trying to apply a polygon mask to a planar tracking media which is UHD. My project is HD and my background image (the building) is also UHD. My tracking window and mask look like this:

Fusion mask and planar tracker

Fusion mask and planar tracker squashed

How can I resize the media or the mask so it fits my background?
