On this, I agree with you and Janina.

Right. But what implications do we draw from this? 

For example: It was agreed, I think, between David and Sean that the 
poster does not need to be taken from the video *file*. But even so: 
What if I find a nice picture that I *do* include in the video file, as 
its first frame, because some UA that I care about do not support the 
@poster attribute?

Thus: I think it doesn't matter that it is part of the video. What 
matters is that it - the frame or the more or less accidental image 
file - has been chosen as poster. A poster is, in principle, not a 
presentational image - the assumption is that the poster tries to tell 
us why we should take the time to play the video.
