I have over the years work with countless productions specially TV commercials with varied directors, actors and crews world wide.  It wasn't until I started editng scenes that I realized what was missing in all the teachings I experienced in Los Angeles.   I became frustrated as an editor and actor what I was seeing with the other actors performances.  I started writing about what I liked and what I didn't like.  I started analyzing and defining techniques that could help the actors performances and importantly keep them in the edit.
