Hi watched your video, it had no sound, now I don't know if that was deliberate or a problem with YouTube, but you need to fix that as it's very hard to figure out what's going on without a soundtrack and maybe some music. Also, it's a very specialised area and would hold little or no interest for anyone to sit through 8.48 minutes of it, who wasn't involved in the same line of work.
