Vertical video resolution name is wrong

[raydouglass]

If a regular resolution video is made in vertical format, it could be classified with the wrong resolution name.

For example, a regular 1920x1080 video is HIGH_DEF, but the vertical equivalent (1080x1920) is parsed as ULTRA_HIGH_DEF.

Maybe this function should consider max(width, height)? Or some other method.
