Of course. Also, for the benefit of other Mac users, I'm including a relatively brief AppleScript that should allow creation of a droppable application using Script Editor.app that will make the process even simpler. To create that application, the user must have authority to do so on the Mac being used. It should also be noted that a properly installed instance of the mediainfo command line application is required. I host this script on my blog (https://prehensileblog.wordpress.com/2023/02/06/applescript-droplet-source-for-using-media-info/), the link for which I'm only including because of the unpredictable (at least by me) nature of any script's disposition when served on a mailing list. Hopefully, no one needs to visit my blog to use the AppleScript, as the blog is encumbered with advertisements that must be endured when visiting freely provided blog sites. As usual, I'll follow up with brief instructions if I discover that the list version is broken but can easily be repaired.
