Done ! Every single musical number now has its background video. They should be crisp enough to be enjoyable on a 1080p display, and lightweight enough to be redistributed and played on even netbooks.
They are all available in the Dropbox "Video" folder.

These videos have no audio track, since Ultrastar / Performous will mute them anyway and just play a MP3/OGG alongside (in sync). They can be re-used for any other language.
I currently don't have enough limit to share the Dropbox folder. Could you please post file-links?
