when using ffmpeg aac codec I see in the log you use the option

-strict experimental -acodec aac -ab 64k

as default, the problem with this codec it is in exprerimental state and it not accurate

I set aac audio bitrate at 64k when encoding and the final result is 68k bitrate

there is another aac codec option in ffmpeg with this option

-codec libvo_aacenc -b:a 64k

produce a more accurate result than the experimental codec, but there is no checkbox
in settings to let you choise as default aac use with ffmpeg.

the final result is

    FFMpeg's own aac codec is superior to libvo_aacenc quality-wise. See FAQ in http://trac.ffmpeg.org/wiki/AACEncodingGuide
    If it is not producing faulty streams, you shouldn't worry about it.
