Two points in response: 1. Roll-up captions are essential for live captioning where the text is transmitted as the captioner types, especially when steno errors and subsequent corrections are factored in. Another issue is the sheer number of words per minute during live captioning, where without roll-up you would end up missing the context half of the time. This usage scenario is very common during live broadcasts in the United States, where captions are not only roll-up, but also appear word by word, instead of line by line. I'll check around if I can find a video clip that shows this clearly. 2. The implementation of roll-up in this video is poor. The positioning and alignment jumps around with every roll up, which of course makes it very hard to read. Now come to think of it, a corollary is that roll-up support by itself is not sufficient. You also need a way to paste on captions live word by word for it to be truly useful.
