I just uploaded two videos on my FTP account (http://astohan.free.fr) (click on the link), in order to shox what can be done with ffmpeg and the Gnome Shell built-in screencaster tool. The videos are in webm format and should be compatible with recent web browsers (you can even download the videos). As far as I know, only Firefox can enable fullscreen for HTML5 videos, that is why I posted them in such a high size (for other people/browsers). Well, at least it can be useful to prove that Guild Wars 2 runs pretty well on Wine (for the skeptical that don't trust us) !
