(I'll revert > anything I disagree with.) Just for the record: I personally agree with Philip's proposal. I believe that there is a problem with missing alt text for the video (and in fact the audio) element, but that is not solved by introducing a <firstframe> element. In fact, such a sub-element will create the need for double accessibility - one for the image and one for the video resource - making it more complicated to provide access to <video> elements. From the user's viewpoint there are not two different resources - there is only a video. So, I don't see a need to introduce an explicit sub-resource to the main video resource for poster images. I do think that the missing alt text may not necessarily be best solved by an @alt attribute, since that has internationalization issues etc. It may be better to introduce an explicit alt text attribute for video which can contain marked-up text. I know there are issues with @alt attribute in the img element and I'd be most interested to hear about alternative proposals for that for <video>. I think that's a more important discussion to have. Cheers, Silvia.
