basic question

[murpcam]

I'm having trouble changing the audio/video bit rate when converting a .flv to .mp4.  Everytime I think i've done it right, the final video comes out with something way off (37kbps instead of 128kbps audio bit rate, for example).

Total newb here, anything helps.

Help me Obi-Wan. You're my only hope.

Obiwan is not here. Should be straight forward like:
Load video in avidemux
In video select MPEg-4 ASP (xvid)
in audio select AAC (faac)
in format select MP4
mark 5 seconds of the loaded clip with marker A and B
save, test the saved video clip in your mediaplayer (VLC, ...)
