I know there's transcripts available for most things if not all but they run a touch long too for most situations.. I think just to be annoying my personal ideal would be the transcripts of the highlights
It's not easy to summarize as a 5 min video as the entire video was an elaboration of this concept. But it's easy to summarize into a couple of sentences.

The other hack I was thinking about playing around with is removing silences, or long pauses, ummms, etc.
