Hi Simon, Well, I’m not saying it’s not sufficient for rendering, it accomplishes the task. If it’s only ever an output format intended to govern rendering, then it’s sufficient. But if one wanted, for example, to save the file for future use, let’s say for future editing/manipulation, I think you can agree that the format is quite cumbersome to reverse, trying to work out the author’s original intent. So, fine for rendering, but not so much for a streaming site that wanted to offer a captioning tool to their clients and store the captions for later manipulation. In that case one would hope for a more straightforward format which would suffice for both rendering and edit/interchange. Just a thought.

The following sample wants to create a single cue with three lines, one left aligned and the other right aligned. This is a very common captioning style. Does WebVTT allow for it? The “position” tag can be used at the CUE level, but I’m talking about at the line level.: >> >> >> 4 >> 00:00:09.530 --> 00:00:12.600 >> <left>this is left aligned</left> >> <center>this is center aligned</center> >> <right>this is right aligned</right> >> >> >> Is there any way to describe it in WebVTT, short of breaking it into three CUEs with identical times and different positions? Simulaneous lines with left and right alignment are much more common than bold and italic in caption authoring, and those have simple tags in WebVTT. Perhaps adding simple tags for them, as above, would be advisable. The region could be created such that the edges are positioned reasonably and the rest is simple to render, with very straight forward css handling. > > Hello Brad, > > No, you need three cues: > > 00:00:09.530 --> 00:00:12.600 align:left line:-3 > this is left aligned > > 00:00:09.530 --> 00:00:12.600 align:center line:-2 > this is center aligned > > 00:00:09.530 --> 00:00:12.600 align:right line:-1 > this is right aligned > > Can you clarify why this is not sufficient? > > cheers > -- > Simon Pieters > Opera Software >
