Question / Help Issues with multiple audio tracks

[Whit30]

I did a forum search on this and have watched this youtube video (https://www.youtube.com/watch?v=3VBzVzAbwrc&feature=youtu.be). In fact I used this video's same exact settings - save for the devices obviously. I keep having issues though. Explained after listing the settings I have setup. OBS ver 17.0.2.

My settings:

Mixer Track 1 - Desktop Audio
Mixer Track 2 - Mic Audio
All other tracks unselected.

Settings:
*Recording tab:

Output Mode - Advanced
Standard
MP4
Audio track 1 & 2
use stream encoder

*Audio tab: Output sub-tab
Track 1 - Audio bitrate 192
name - stuff1

Track 2 - Same as above
name - stuff2

Audio device tab
Desktop audio Device - my soundcard
device 2 disabled
Mic - my mic
2 and 3 disabled.

So, I hit record and OBS shows the green sliders that it's picking up audio for both devices. After I finish the recording it only picks up one track. It sometimes switches which track it picks up. I've recorded footage of this if someone needs further information.

Additional information - in the scene I do have video capture device/Display Capture/Game Capture. I don't think that's the issue as I've created another scene with just display capture to test it and that's doesn't work either.

How are you checking your recordings?

Hitfilm,windows media player,whatever the movies and tv program is for win 10, and windows movie maker. Obviously, only the first one I could use to edit the separate tracks. Just listing what I tried for playback. They don't all pick up the same track either.

Example - media player will pick up track 2 (the mic) hitfilms will only see track 1 (desktop audio) - from the same mp4 file. So, OBS is probably working correctly and the programs themselves aren't reading the file correctly.

Use VLC

Re-save them as MP4 with that? Any noticeable quality loss?

Edit : Nevermind it's like hitfilms only picks up the desktop track.

VLC lets you select which of the audio tracks inside the file you want to listen to, so you can use it to verify that both tracks are present.

 

[Whit30]

You're correct it shows both of them. So - ahh now we know OBS is working correctly. Shouldn't hitfilms be picking them up as well?

A lot of NLEs have trouble with multiple audio tracks inside MP4 files. You might need to extract the audio (with e.g. ffmpeg) and import it separately. It's what I do.

Ok, thanks folks I appreciate the help. I just tried Video Pad as well. What I might do is leave it like is (two tracks)- let the editor pick up the desktop audio and then use VLC to get the mic audio. Though your way is probably cleaner - I'll see if I can figure out how to do it your way.

So, I don't double post - yeah just recorded normally let it pick up the audio. Then used VLC to convert the same file into MP3 and it picked up the other audio. Loading them into the editor and we're golden. Thanks again.

Actually, I am gunna double post. This didn't work everytime as the program would still just randomly pick which track it wanted. So I downloaded audacity with the ffmeg plugin and it works like a charm. Ask you which stream/track you want open in it. Thanks again for all your help.
