The definition in this video is substandard but I was already in the mindset of watching an educational video so I was pleased that it was at least in color.  The definition also slightly aided in the feeling of an aura with regards to the old techniques of writing.  I feel like if i was watching this in HD it would look more like someone using tools they just took from a showcase in a museum. With 1970s definition, the actor looked like he may have owned these items personally especially because of his ability to use them with precision.
