How do you extract an .MP3 from an .MP4 file using iTunes?
I have figured out how to import a home video into iTunes (video taken with my iPhone 5S), and have figured out how to use iTunes to convert the video (recorded in Quicktime) to .MP4 format ... but I cannot then use iTunes to "Create a New Version" and have it allow me to select .MP3 as a choice. It's on the list, but it's greyed-out. Apparently, on a MAC, if you hold down the "Option" key, it will then allow you to select the .MP3 format, but pressing "ALT " (generally the PC equivalent) only closes the drop-down menu on me. So ... what do I do here?
I really don't want to have to download a different program to do this, especially since it seems that iTunes can ... I just need to know how.
