When animating camera focal length, motion vectors in EXR exports are calculated from the wrong center point, causing incorrect motion blur in post-production.
Expected: Motion vectors should emanate from image center (0.5, 0.5) Actual: Motion vectors emanate from upper-left corner (0.0, 0.0)
This results in directional motion blur instead of proper radial zoom blur.
