Following up from today's seminar, the Development & Research folks may want to take a look at this journal article that recently came out if you haven't already: Rich, P. & Hannafin, M. (2009). Video Annotation Tools: Technologies to Scaffold, Structure, and Transform Teacher Reflection. Journal of Teacher Education, 60(1). Also if you haven't seen these, you may want to look at the publications and presentations that have come out of the VITAL project.
