For me these are not an option that can be turned on or off according to aesthetic preferences. What I am saying is that certain types of captions are not readable with the normal pop-up procedures. For me the question is not whether I am consciously reading captions, but whether I can get the content of the video. I realize that not everyone has the same preferences, but there are good reasons for displaying the captions this way for 30+ years. Roll-up captions are a conscious usability trade-off, not a mistake. As far as live captions are concerned, the law in the USA stipulates that TV content shown on the web, including real-time or near real-time, has to be captioned, just as it must be on the TV broadcast. So, there is definitely a need for live captions on the web. If WebVTT won't support this use scenario, this means that a large part of the reason why captions are needed on the web is just disregarded. Which leaves us ... with what?
