    I have a video and I'd like to know what the audio bitrate is..
    The properties window only shows the total bitrate (audio + video)

    Thanks in advance

    If you have the command-line tool "ffmpeg" installed, just enter

    Code:
    ffmpeg -i [i]filename.mp4[/i]
    This is what I get (shortened for space reasons):


    Code:
    $ ffmpeg -i Wipeout.m4v 
    FFmpeg version SVN-r25017, Copyright (c) 2000-2010 the FFmpeg developers built on Sep  1 2010 09:53:14 with gcc 4.4.3
    
    Seems stream 0 codec frame rate differs from container frame rate: 5994.00 (5994/1) -> 29.97 (2997/100)
    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Wipeout.m4v':
      Metadata:
        major_brand     : M4VP
      Duration: 00:02:06.86, start: 0.000000, bitrate: 1039 kb/s
        Stream #0.0(eng): Video: h264, yuv420p, 480x270, 905 kb/s, 29.97 fps, 29.97 tbr, 2997 tbn, 5994 tbc
        [b]Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16, 124 kb/s[/b]
    At least one output file must be specified
    If you don't have ffmpeg installed, here is a link to some pre-compiled binaries:

    VideoSpec (I prefer that, though it hasn't been updated since 11/2009), MediaInfo Mac (10/2010) or MediaInfo (10/2010, there is a Mac OS X version to download, VideoSpec and MediaInfo Mac are using the same library as MediaInfo)

    Quicktime 7 Pro has this feature. You can go into movie properties and get information on each track specifically.
