Anyone know how to deal with video files (.mp4) containing multiple audio streams/tracks?

Hi folks,
 
does anyone know how to deal with video files which contain multiple audio tracks?
 
I've been given a mpeg4 (.mp4) video that contains multiple audio tracks, and when I import into sonar (I have platinum) I only see the first audio track.
 
I've confirmed there are indeed five stereo tracks in this video, premiere pro sees them, sony vegas sees them, mediainfo (utility) sees them, but Sonar only give me the first one.
They have various mics, foley, placeholder music recorded to different audio tracks for me to process/mix etc.
 
Has anyone else come up against this?
 
Any help or hints on how to deal with this greatly appreciated.
 
Cheers - Cliff

Is exporting brodcast wave files from a video editor, doing your work, and reversing the process for re-assembly an option?

Thanks Michael, I suspect that may be the only option here. I haven't managed to find any options or hacks inside Sonar to make it import multiple audio tracks. There's simply an option on the video import dialog to import the audio, which only get's me the first audio track.
 
It's amazing what some people come up with at times on these forums though. I'll hope that someone knows some "secret squirrel" undocumented configuration file tweak that let's it import all the audio tracks.
 
Otherwise, long term I might investigate Reaper to see if it can do this.
It's about time I added another option to my audio tool chest, but I'd be almost overjoyed if I could do this easily with Sonar
 
Cheers  :-)
 

I have briefly worked with video in Sonar but I usually add a track to a video. Sonar is a basic video/audio editor and I'm pretty sure it only imports a stereo audio track.
 
Maybe try importing only the audio as a separate stem and add it to the video later.The format your're coming from is showing 5 tracks. Can you export the individual tracks into Sonar from it?

Magix has taken over from Sony and the Video editors are on sale weekly. I picked up a copy of Vegas Movie Studio 14 Plat for $30 and a week later it was on sale for $19. 
Check the versions as the basic version only support x amount of tracks, but the full versions I do believe are unlimited tracks. 
Sonar is not a movie editor.

Thanks everyone, I've been digging into the file I was sent for more info and googling like a madman, I might be on to something ... but I badly need some sleep.
 
I'll report back here some time in the next couple of days or so once I get a chance to try some things and talk to the people who produced the file.
 
Here is what I've found so far from digging around, and a couple of emails back and forth.
It may not help me with this particular project, but may help with this client and future work from them - we'll see :-)
 
The mp4 file was produced using OBS (Open Broadcaster), and the audio streams are all AAC format, which is where the issue probably is for Sonar. I believe there is a reasonable possibility that if the audio streams/tracks were PCM rather than AAC encoded, Sonar might just suck them straight in without any problems.
 
They can't provide me a file with PCM audio tracks because it was from a live session and this is what they recorded.
 
It looks like OBS can indeed output multiple audio tracks to standard uncompressed PCM, but not with the settings they are using (and they don't seem to have a handle on this at all).
 
I'll install OBS in the next day or two, see if I can produce a video file with multiple PCM audio tracks. If I can do that, I'll check what happens in Sonar.
 
I'll report back as soon as I get through all this :-)
