It seems that changes to extras aren’t being recognized for me. I did The Plex Dance ™ and my changes to the extras finally appeared. It seems that neither adding new nor removing existing extras changed the extras that were being displayed. Instead I needed to Plex dance the entire movie folder just to add one new extra. Sigh. At least it is done now.
And the -video does indeed work by tagging those extras as Music Video. Hopefully that new option (and any others) might be added to the documentation so we can actually use them.
Thanks, Otto, for getting me on the right track.
