Use denominators as the litmus test for generating profile.

This allows converting all producers to meta.media.width and
meta.media.height while not attempting to auto-profile the image
producers, which can potentially hold extremely large images and do not
contain any inherent frame rate. This also protects from potential
divide by zero errors.
