	It's genesis may not matter, but its content does. As a screen reader user, I would like to know what that image contains. I'd also like to know what the movie contains.

	Whether the image is the cinema poster, a still from the video, the film company's ident, or something else entirely, I'd like to enjoy it. This shouldn't be confused with wanting to know what's in the video, anymore than you'd confuse looking at a poster on a cinema wall with reading a promotional description of the movie, or watching the movie itself.

...which is why I had originally proposed <firstframe>, as it was also agnostic to the genesis of the visual display. 

What you are failing to understand is what is being asked for in terms of "descriptions" - the non-sighted users I have talked to want both a description of "the film" AS WELL AS a description of what that initial first image on screen actually LOOKS LIKE. They are degrees apart in how they would be described, and what they mean to the non-sighted user.

This discussion remains circular, with no clear understanding of what is actually being asked for. 

I, and I don't think anyone else, really cares where the image comes from (although allowing @poster to reference a uniquely different first image does shake things up significantly) - what is really required is 2 types of longer textual description. It is entirely reasonable that not both will be required all of the time, but that there will also be times when both will absolutely be required, and currently we can't do either - we should be planning for both scenarios, and stop insisting that only one scenario is ever going to emerge.
