The point wasn't that it is OK for UA:s to distort video because there
are people who don't notice, but that some people do/will encode video
with the wrong aspect ratio without noticing/caring. The general
consensus seems to be that this isn't worth the effort fixing.

But in any event, if a CSS solution is in fact possible that would be
much better than any video-specific solution. I don't think CSS
transforms can do it though, unless someone can give an example?
