My understanding, though, is that it doesn't go far enough. We have also the circumstance: <video src=kittens.webm alt="two lovely kittens in a basket"> In other words, there's an implicit poster= As I understand it, the spec explicitly defines what happens in this second instance--where there's no poster specified. The spec says that the first frame of the video is to be displayed. Thus, the behavior is the same, the user's sees the same result, as if there were an actual poster=kittens.jpg specified. I would submit, therefore, that the aabove alt on the video element should also be specified by the spec. Inasmuch as the spec sees fit to provide a mechanism for what I would provisionally call a virtual poster, it should similarly specify the appropriate alt mechanism for that poster. So far, so good, in my mind. However, it seems we may have more elaborate requirements than a simple alt, i.e. a long description, i18n tagging for any text in the poster, etc. Janina
