Take a look this selection from film_agk.log:

Look at the purple line. How is this 1.18518518518519 calculated? What are the numerator and the denominator that give rise to that figure?

I apologize if this has already been explained somewhere. I couldn't find it.

Regards.

It is distortion aspect ratio (i.e. how pixels should be adjusted to achieve correct AR) of an input source. For instance (720/480)*(9/16)
