How do I know if my .MKV's are 1080 or 720?

Hell. I'm creating an Excel spreadsheet which will later become a webpage I use to look at my movies. I was wondering how I can tell which of my movie files are 1080 or 720? I use MediaInfo to show me the resolution. For example:

Black Hawk Down.MKV is 1280x532 (2.406) at 23.976fps.

Is that 1080 or 720? I just want to be able to say what the quality is. This movie is 8gigs but the resolution appears smaller than most of my 8gig 1080 movies.

Another example. When I bought Star Wars - The Clone Wars it said 1080p on the box. Yet, my backup from Ripbot is only 4.3gigs which is usually how small my 720 backup MKV's have been. Resolution: 1920x820.

Is there a formula? Thanks!!

There isn't really any formula for determining the quality of a movie. However, for the most part any movie that has a horizontal resolution of 1280 is considered to be 720p, and likewise a movie with a 1920 horizontal resolution is 1080p.

The reason for this, using your Black Hawk Down rip for example, is that because of the 2.4 aspect ratio of the movie and the fact that programs like ripbot just crop the black bars off the top and bottom of the video, you got a resulting resolution of 1280x532, but it's still considered to be a 720p classification. If ripbot didn't crop off the black bars then your video would have had a frame resolution of 1280x720, whereas the actual movie itself would only be taking up a resolution of 1280x532 within that frame.
