I have a problem with the audio encoding. The video encoding is fine.

I demuxed mpa from mpeg2 and want to encode it to 48kbps abr mp3 using gordian knot. I selected 'mp3 custom parameters' and setted 'lame' as '--alt-preset 48'. I couldn't encode it @ 48, I could encode it @ 96 though.

I could encode mpa to 48kbps mp3 using vdubmod. I loaded mpeg2 file and streams -> stream list -> conversion I changed 48khz sample rate to 16khz. So, I could produce 48kbps mp3 file. I don't know how to apply this on gordian knot because I don't know any lame commands.

How can I set 'azid' and 'lame' for encoding @ 48?

Thanks.
