Creating Video with switchable Audio Tracks

scooby wrote on 7/18/2018, 2:21 AM

I was hoping to create a video with selectable audio track much like those in dvd.

For Example, a video clip with 2 audio track.

Track 1. the original audio intended recorded during filming.

Track 2, The original audio with Director speak for narrative purpose.

I research a bit online with AVI and Muti Channel mixing, Playing with audio track and audio Bus setting and still fail to produce what I want. (in fact, i think my concept of Track / Channel / Bus is vague and not solid causing all sort of problem).

I hope i can get some help from here... many thanks.

PS , I am using Sony Vega Pro 10.0

The answer will probably be based on what your delivery requirements are for the file. What format will the user be playing back where they need to choose between the two audio mixes? You may need to render two versions: i.e. Quicktime #1: mix without director commentary; Quicktime #2: mix with director commentary.

You CAN make a quicktime (or Mp4) with multiple audio tracks. We often make 8-channel files, with the 5.1 surround on ch1-6, and a stereo mix on ch7/8.

Thanks you so much flyerstil.

I am just trying to render a file with selectable audio track for a media player (android box). Which support many formats. I note that many files that I came across with from the internet such ask MKV/AVI or MP4 is capable of track selection.

From my Vegas pro 10, it seem that only Windows AVI file have the Multi Channel Mixing option available.
however, even when i follow the instruction step by step, i still fail. the player i use to test the output file is VLC player. (which usually work fine with all sort of file type, with audio track selection)

The instruction i follow is here:

In Most player... changing audio stream is know as Selecting TRACK 1 or Track 2 etc.
Now i wonder...
Vegas is adding different audio stream in to different BUS, and each BUS is consider as Channel.

my output file now have 3 channels. (from the propensities)
however, the VLC player still only show only 1 audio track is available.

Stream / Bus / Channel / Track ...

i am so confused.

More research and i found this:

You need a wrapper that takes multiple audio. Vegas does not output multiple audio tracks, only multiple audio channels.
You can make mp4 with multiple audio in Handbrake.
You can rewrap your original video with multiple audio in MakeMKV.
You can mux multiple audio in AVIDemux, or dozens of other utilities.
You can make a DVD with multiple audio tracks.
You can make a BluRay with multiple audio tracks.

A workflow that I used in the past:

1) Render video to an elementary stream using one of the Blu-ray templates.

2) Render each of the audio tracks.

3) Multiplex video and all audio to a .m2ts wrapper using tsmuxer.

Exactly. That's what I'd do. render the audio files separately so you have your two audio mixes as separate versions (presumably 2-channel stereo files). Multiplexing them to the video as a 2nd step is wise. You can also use Quicktime Pro to do this, and end up with 1 video file with 2-2channel files attached to it. This way, also, you only have to render the video once.
