iPhone X Using only iPhone, how can I save a video to then convert to an mp3 to send to a friend via iMessage

[HappyDude20]

i want to send the Star Trek voyager one opening soundtrack to a friend. Not the entire 39 second song but just 7 seconds.

I know how to screen record a video when using the YouTube app but then I’d like to take the audio from that recorded video and turn it into a 7 second mp3 file to send to my friend via iMessage. How can I accomplish this?

 

[now i see it]

There are lots of apps that will do this in the App Store.

Search: iconv

The one I'm using has been discontinued so I can't post a link.

Prob faster to remux with handbrake on a Mac.
