A Request for Assistance with Accessible Video

All,

With my sincerest appreciation of your help given in advance, I am a bit uncertain about the accessibility of this Youtube video - aside from Youtube issues itself - and would truly value your feedback, suggestions comments and so on. My opinion is that key visuals must be audio described, perhaps in text as a caption.
