Thank you very much (merci à vous très beaucoup) in french.
BUT; Technical question : why every second or less , we have a black n white pic ?
I don't colorize videos but from my understanding every single picture of the video (25-30 per second) is colorized and depending of the changing of lightning/shadows/etc. I guess that the coloring of the pics constantly change and you end up with some pics which are more or less colorized than others.
But it's just guessing on my side....
