im trying to combine two of my video things and they have different audiostreams so it won’t mix. does anyone know how to change the audiostream of a video from ac3 to mp3?
Install any necessary codecs (K-lite Codec pack or K-Lite Mega Codec Pack)
Virtualdub ->Audio streams->MP3->CBR (or Virtualdub Mod)
But for the two audio streams, you are better off converting them both to WAV (check they are the same sample rate), join the avi’s (using Virtualdub mod) & converting the audio streams at the same time as the join.
