@nigelmegitt Aligning subtitle cue changes with video frames is very much important too for high quality media playback purposes. [Here's a quick demonstration of subtitle scene bleeding](https://www.youtube.com/watch?v=SHjiY6qLmbY) that you can get if the cue changes are not properly aligned with frame changes - in this example the timing is a whole frame off (~42ms), but shorter bleeds are similarly notable and extremely ugly. It's true that frame alignment may not be always desirable (mostly if you're dealing with very low FPS video), but it should definitely be *possible*. As I mentioned earlier, desktop playback software does not have issues in this regard, and I'd really like for that to be the case for web video as well.
