Aside from the informative "THE CUTTING EDGE" documentary, there is also a film made my Gabriele Voss titled "Cuts in Space and Time". It's in German with English Subtitles.
The DVD is the link
It's great for both narrative and documentary editing! The director Gabriele Voss (along with her husband, Christoph Hubner) have been doing amazing cinema verite works. And they are also exceptional mentors!
