Where are the Music clips embedded in the iMovie app for a Mac mini?
Last year I made 2 or 3 iMovies using my Mac mini and the music clips embedded in the iMovie app. I'm trying to access these music clips for an iMovie I'm making. However, all I can find are sound effects. What is the problem? I notice that some of Youtube instructional videos are using versions of iMovie in which the audio and the video are shown as separate options. In the version I've got on my Mac mini these are shown together.
I don't want to use the music I've got on iTunes because this will produce copyright problems but I did notice that out of the 39 hours of music I've got on iTunes, it only shows the complete works of Webern and some songs by Lightning' Hopkins. I checked the app and it was last modified 1st August 2023. Is this a case where Apple have changed iMovie so that it doesn't include music clips but have forgotten to tell anyone? My Mac mini has the M1 chip and is running Ventura 13.5.1.
