Multi-audio

The following formats support multi-audio output:

Notes

AVI

It is the default save format. A second CBR audio track can be added using Audio→Second Track. It can be either MP3 CBR or AC3.

MPEG files

If you use MPEG A+V (PS) as the output format, you will end up with a VCD, SVCD or DVD stream. Of course the audio must also be suitable for SVCD/VCD/DVD use. Avidemux is now using libmplex for maximum compliance.

If you use MPEG video as the output format, only the raw video elementary stream will be saved. That means there will be no audio and that it is not suitable for VCD/SVCD/DVD authoring. You have to save the audio only (using Audio→Save) and use mplex or tcmplex to rebuild an MPEG PS stream.
