While video can show how an animal might react to a shot, due to the difference in camera angle to shooter, it may not give a true indication of the track of the bullet. For this reason Kevin Robertson's "The Perfect Shot", or the book "Nyati" from African Hunter Magazine might be a better source from an educational point of view. The Boddington video is presented in an informative tutorial format, and does deal with bullet tracks from various angles and I am satisfied that I got good value when I bought it. It just seems to me, that the video together with the books, give a more complete picture than either one alone.
