That's quite the job you've done! However... doesn't Youtube have a close captioning subtitle setup that allows you to do it on the original video for him? I think it's easier to do than subtitling in most video creation software as well.

yes it does, it was my first aproach.. but the video was locked for contributions.. better this way i guess, since when you enables it anyone could also add comments and other unwanted stuff to the video.
