IMO this should be a feature of TextTrackCue and has no relevance to VTTCue specifically. There's implementation overloading here that is mixing concerns unhelpfully.

They would be play(start, end) Where start and end are the times in seconds. I know you can do video.currentTime = start ; video.play() But there's no real easy way to stop it to play a clip The media fragments URIs spec  handles this quite nicely by adding to the URI #t=start,end But yet there seems to be no way to do this in JS, resorting to changing location.hash and then doing a reload, which seems a bit of a kludge I may be missing something extremely obvious, if so, I'd love to know!  https://www.w3.org/TR/media-frags/ The pauseOnExit attribute on VTTCue can be used for this purpose. See https://html.spec.whatwg.org/multipage/embedded-content.html #text-track-api:the-audio-element for an example. Thank you for both answers! I found pauseOnExit to work very well for my use case. I ended up with. v.addTextTrack('metadata') cue = new VTTCue(start, end, '') cue.pauseOnExit = true cues.addCue(cue) v.currentTime = start v.play() Regarding var cue = new VTTCue(start, end, ''); As best I could tell that last parameter is a 'message', tho Im not sure I got any message when the video stopped, even when I populated it. Maybe I wasnt supposed to. I'm quite happy to use this solution. My slight concert is whether there are any side effects from adding a TextTrack to a video. Should this be considered best practice, or would there perhaps still be room in future for (start, end) parameters? -- Simon Pieters Opera Software
