4.Format specific
Avi
It is the default save format. A second CBR audio track can be added using Audio->Second audio track. It can be either MP3 CBR or AC3.
Mpeg file
If you use Mpeg A+V (PS) as 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 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 a mpeg PS stream.
