Video with multiple user-selectable music soundtracks

With FCP 10.6.3 is it possible to create a video with multiple music sound tracks...

For example, the video shows a couple dancing and there are several music soundtracks, say A, B and C.

While running FCP, I can alternately disable A and C and enable B  to see the couple dancing to B.

What I want to do Is Export the video with all the soundtracks where the user can select whichever music (A, B or C) is preferred at the playing of the video.

I pointed this out in an early post what's doable in Quicktime Player 7... The ability to enable multiple selectable language or music tracks all in one video clip via Command + J (Show Movie Properties). In this case instead of exporting eight separate videos of the possible combination of language v. music (some 400GB all together) one only needs the single 56GB export and access the movies properties to select the language / music combo so desired. (Not aware of any other application that has access to these properties and the ability to turn them on or off.)



 

Oh, Thank you so very much -- I never even considered Quicktime...

I didn't think that FCP could do it -- but it doesn't hurt to ask...

I thought that my only recourse was to write apps or a website in Xcode to stitch it all together.

I'll give the latest Quicktime a go and see if I can make it happen...

I'm on a Mini M1 running the latest macOS Ventura beta so I have to work around a few issues.

If I get it done, I'll post the results here!

Thanks again, VTC -- you're the best!
