MediaInfo Mac: multimedia information tool for Mac OS X
MediaInfo Mac is a Mac utility for displaying information about audio and video files. Similar to GSpot for Windows, MediaInfo can provide codec information, bit rate, resolution, frame rate, and aspect ratio.The program displays a URL to the codec used (in case you don't have a capable player), and you can export all of the information to a text file.
If you open a file in VLC and press Apple+I ("Get Info"), you can get similar (though limited) functionality by clicking the "Advanced Information" tab.
