And you are not helping by using acronyms that are not the same as used by
ffmpeg. I had never heard of "storage aspect ratio" before.

The SAR acronym, for ffmpeg, means sample aspect ratio, and is probably what
you call pixel aspect ratio.

The other aspect ratio that ffmpeg prints is the display aspect ratio.
