Automatically Split Multitrack Audio/Video Into Two SEPARATE Files

[revvmusic]

Hi all,

New here! Been scouring Youtube, this forum, and Reddit but can't find an answer for OBS RECORDING.

I have been making karaoke videos using OBS. I set up advanced audio to record my desktop audio and mic audio separately and it works great. However, I would like to be able to edit the microphone audio only post-recording. Because I use different mics, settings, and different karaoke videos/songs have different levels, it would be great to be able to edit the output level of my mic after recording. I would also like to be able to put a bit of reverb on the vocals too.

However, all the multitrack video records are exported as one video file. The video editor I am using (Descript - makes it easy for captions) does not recognize that each video file has separate audio tracks. I am able to separate the audio using Da Vinci Resolve.

However, if I could have OBS create two separate files, I could then easily edit them without having to first split the audio in DaVinciResolve, export, and then import into Descript. Example below:
1. Video and karaoke audio (MP4)
2. Vocal mic audio only (MP3)

Any way to do this?
Thanks!

OBS does not have the function to record audio as separate files. (they wouldn't be mp3 anyway, the audio is encoded using an AAC audio encoder)

Thanks for the reply Harold! Do you have any suggestions for easily splitting the audio/video afterwards besides DaVinciResolve? Trying to make the process as streamlined as possible.

If you're okay with the command line, then you could use the Run action here:

Advanced Scene Switcher

This plugin will allow you to automate various tasks using "Macros". Macros consist of a list of conditions under which a list of actions will be performed. Examples and guides can be found in the wiki. Feel free to contribute! If you run...

obsproject.com

That's the same as /path/to/program "arguments" "to" "that program" on the command line, run once every time you stop recording, from OBS's working directory. If you need a different working directory, then you can set that here as well. You might, for example, call ffmpeg from here, after some education in its options:
