Hi, In the case where the video is changing quickly (and espescially the colors behind the subtitles), having a "constant" contrast helps the reader. This can be achieved by adding a background to the text. There are couple of examples of this in the use case page (http://wiki.whatwg.org/wiki/Use_cases_for_timed_tracks_rendered_over_video_by_the_UA), like the one with the text "children of my age, when they were growing up". However, in contexts where there is a lot of text, the background of the text will hide a big part of the video. A way to have a more discrete "constant contrast" could be to have a text outline. For instance, a white text outlined in black. There are actually couple of these in the use case page (like the image with Keanu Reeves). After a quick investigation, text outline can be achieved by using text-shadow (examples : http://www.w3.org/Style/Examples/007/text-shadow#outline) or even the CSS3 text-outline property (http://www.w3.org/TR/css3-text/#text-outline). This property is not implemented anywhere as far as I know. However, webkit implements text-stroke ( http://webkit.org/blog/85/introducing-text-stroke/) which seems to do the same thing.
