I read the spec [1] and while I find it generally well thought out and covering a lot of use cases, it however fails to cover some of the more advanced use cases seen in action in some less-than-official subtitles. For example as seen in ASS subtitles [2] I am talking about animation for the subtitles. Two main types of animation to be specific. The first is subtitles that try to follow movement in the video. From an implementer standpoint it means freeform animation of the cue as displayed with timing information relative to the cue. The css keyframes system may be relevant here. The second is subtitles that display karaoke. That is, visual aid to the viewer for which syllable has, is and will be audible next. This is traditionally used to allow singalong for songs. Best regards from someone who likes subtitles. [1] https://w3c.github.io/webvtt/ [2] http://docs.aegisub.org/3.2/ASS_Tags/
