Universal Subtitles is a subtitling service, which works with existing video resources such as YouTube. They use custom embedding code for rendering the subtitles on top of the video, and as such, the plain YouTube embedding feature in Viper’s Video Quicktags won’t show the subtitles. It’d be nice if VVQ could support embedding videos through Universal Subtitles, with the added accessibility that having subtitles on video brings to viewers.

It’s probably not a simple task, as Universal Subtitles isn’t limited to just YouTube, but even having just subtitled YT for starters would be great.
