Displayed Frame Size vs Encoded Frame Size

[iMaiden]

I have a mov file (Pro res HQ) that has been encoded at 960x 540 and put in an mov wrapper with a 1920x1080 displayed frame size. I have this http://www.tek.com/file-based-qc/cerify-video-content-analysis software confirming this.

My question is this: Does anybody know of any software or way to display the actual frame size of the video essence without just looking at the metadata? This cerify tool does it but I want to do it outside of this software.

I've had that a lot with ffdshow through avisynth and actually considered it a problem as I wanted the anamorphic. That option aside, tried mkvmerge or the like to extract?
