Video subtitles

It would be nice to add a video subtitle option to Prezi’s videoplayer. Many videos on YouTube are already linked with subtitle files, sometimes multilingual.

I would like to create my own subtitle (in *.srt format), associate it to my own video and upload both to my presentation in Prezi.
Popular players on different platforms, like VLC, Windows Media Player, Quick Time Player, MPlayerX, Totem and even Media Player Classic provide the option to show subtitles, and this would be a nice feature in Prezi, too.

If you upload a video to YouTube and make it subtitled and then embed it in a Prezi presentation, it can be played with subtitles.
