This is an old thread, but I think the point of the video was really more of a promo for the Heiland Split Grade printing system and the Heiland densitometer which I don't recall anyone talking about that commented on this thread. A very cool system indeed - really powerful. In the age of computers I would love to see a version of the Split Grade system that somehow hooks up to a computer/laptop, reads the entire negative (like a scanner), and has software to make selections on a laptop display with a red screen mode (much like in PS) where you can select the exposure of different sections - along with a variable LED light head that can somehow expose different parts of the image differently instead of hand dodging and burning - almost combining an enlarger with a scanner, but the exposure remains on silver gel paper. I know, I'm only dreaming. I'd bet if analog printing still had a large market this is where enlarger and analyzer tech would have taken us.
