After a quick look at those, single may actually be a good approach. I haven’t kept up with it, but there has been extensive discussion concerning guidelines for videos as singles. Some more reading if you feel like it:
- STYLE-2428: Step by step video (releases) guidelines thread
- Video style guidelines (draft) - MusicBrainz Wiki - @UltimateRiff, @reosarevok: what’s the status of this draft? Is it at a point where a beginner would do well to follow it?
- Collection “Video as release (YouTube)” - MusicBrainz
Set recording length = video length.
