Olivier is this your video? And if so do you know this person? I know this is not you on YT
(I've been away from the Internet for a little while.)
Yes it is my video and no I don't know the person who made this copy on YouTube. It's not the first time and, well, there isn't much one can do against that, even though it can be irritating. At least the original on Vimeo is in much better quality.
