Sorry if this has been answered before. I did a search and only found one topic even remotely pertaining to it.
I want to encode dual audio tracks in an .mp4 container, and I was wondering if this was possible with Zarx264gui. I ask because I'm encoding a speedrun using the same methods that I would use to encode an AMV (in other words, I'm using A/V guide on this site), but I want to have the game audio on one track and my own commentary on another. The container is non-negotiable - it has to be .mp4.
I'm a novice to this part of encoding, so any help would be appreciated.
