It's a shame that if it would presumably be too confusing to renamed  
poster to be "placeholder" as in

<video src=kittens.webm placeholder=kittens.jpg>

because (apparently) video producers are used to the word "poster" and web  
developers are getting used to the placeholder attribute on form inputs.

Why can't this work?

<video src=kittens.webm poster=kittens.jpg alt="two lovely kittens in a  
basket">

with the alt being the short textual alternative that can be used to  
seduce people to click the video (presumably, what the explicit poster or  
first frame is to do), at which point the full glory subtitles/ tracks etc  
are unleashed?
