How do I split audio tracks 1, 2, 3 etc. in an video?

Note, this is distinct from the question of how to split video into its sound and visual components.

I'm talking about a video which, when recorded as visuals with 3 different audio tracks: one track with video game music only, another with my friend's voice and a third with my voice only.

So when I'm manipulating the content in Camtasia, I need to be able to edit the audio tracks separately.

Hey,  when you are importing the media I am assuming that each one of those audio tracks is separate from each other.  After importing each track into Camtasia you will be able to add the audio onto separate tracks into Camtasia.  The individual tracks may be used for audio or video they are not specific to either.  Since each audio will reside on a separate track you will be able to edit them individually.

or export individual tracks from the OBS recording software so that you can use them in Camtasia.

I can try, but it is disappointing if Camtasia can't extract the 3 audio tracks from the mp4. I mean, the information is contained within the file

VLC is a unique piece of software.  I found this info http://www.tomshardware.com/answers/id-3304402/extracting-multiple-audio-tracks-mp4-file.html

It appears to me that there are very few pieces of software that would separate audio from an MP4 in the way you are trying to.  So I am not surprised that Camtasia cannot do this.

I will have to look further into this. I'm sure it's doable in third party software if not Camtasia because because I saw a YouTube how-to for gamers recently but can't think of it off the top of my head. I'll report back if I make any breakthroughs. Thanks for persisting with me on this one

Have you tried separating the tracks in Camtasia? If you only end up with a single track of audio, there's your answer and there's nothing I'm aware of that will change that behavior.

Yes, and that's exactly what happened.

For what he is trying to do I agree with Rick and this is not possible to do in Camtasia Studio. It is because of Windows sound cards only having one input and output to use too. Camtasia will record video and audio of your voice and the system sounds from another video or online game and conversations with Skype etc.  But the fact remains that it is put into one .mp4 format or whatever you choose when in editing and if you separate the audio and video it will only show the one audio track and that audio track has the other persons voice, online gaming video sound etc. but it is not possible to separate the audio from each one to separate tracks. It may be possible with more money involved on using Pro Audio USB Interfaces so you would have more than one device for recording your audio.

For example I can use my Presonus USB 2|6 or 6|8 Audio Interface and any software and Pro Audio Recording DAW Software and it works good. But you would have to have the correct devices to do so and record into a Multi Track Audio SOftware with each Channel/Voice/Sound on it's own Tracks in order to accomplish this task. There may be another way but I find this most effecient but it gets expensive to have a setup like this for doing what you want to do.

This is unfortunately a limit of the Windows OS and not Camtasia Studio in my opinion. Hope this helps. Have a great day/night.

Cheers - Fred.

ptrcao,

 Those methods with using the other software like Voicemeter, VB, etc. will work but the user would want to keep in mind that they can be memory resource hogs too. The more audio or video you are putting into your system and the more software apps the worst it gets with using your memory and your speed might slow down also which can cause lagging. So, with that being said the users may want to make sure they have a pretty hefty system if they plan on doing a lot of this and saving their files while working. This is why I use two audio interfaces or just the one;s I mentioned from PreSonus called the Audiobox 2|6 or 6|8 which are USB and work on both Windows or Mac computers and takes up less resources for these needs.

This is just my experience and opinion and no one is going to have the same opinion or setup and what they want to do is a whole new subject as everyone does things differently. Nice tutorial and explanation. Thanks for posting and have a great day/night.

Fair point regarding memory demand of my approach, Fred. And yes, I wish it didn't have to involve so much third-party software. It's the poor man's solution I guess, as it's free. Unless they have to buy more RAM. lol It's good that the world has our two solutions available to them with with differing cost tradeoffs.

What does your audiobox solution cost you, if I may ask, Fred? I'm tempted to look into getting it

ptcrao,

 The PreSonus Studio 2|6 USB 2x4 USB Audio Interface with 2 XMAX-L Preamps runs around $200.00.

And the PreSonus AudioBox USB 96 runs about $100.00 so a total of around $300.00 for that setup give or take with the cables to connect them to each other.

The software recording DAW I use is PreSonus Studio One 3 Pro and it runs around $400.00 but users can use Audacity or any other Mult-Track DAW Software of their choice.

It can be kind of spendy but the quality is great and I am in no way saying this is the only option but what I choose to do for my setup.

In the near futrue me and another Pro Audio guy are planning on making some videos to show how this kind of a setup would work for users that want or are looking for this kind of Pro Audio Setup. It will be a paid video but the cost should not be to much.

I plan on upgrading my Interface after the first of the year so I can record more Channels for Bands etc.

Hope this helps you.
