I'm Bob & I train with the Australian College of arms down in Brisbane (Australia obviously). Though the extent of my video anaylsis so far has been looking at bout footage and thinking to myself 'I remember myself being much faster and more coordinated than this video would indicate' I've been searching for some tools to help with this.
The first I found is Kinovea which is a Windows based open source video analysis program for sports http://www.kinovea.org/en/
It's got slow-mo replay, frame by frame and has measuring, tracking and marking tools. The only downside so far is video export is twitchy. I've been unable to get it to output footage with the proper timing - everything seems double speed. Though if you stick to using the video in program that won't be an issue. There is even the potential to go through bout & tournament footage to work on stats tracking.
The other is Tracker Video Analyisis and Modeling http://www.cabrillo.edu/~dbrown/tracker/
I haven't used this as much, it lacks the sports focused toolset of Kinovea though there is probably lots of really smart things you can do with it if you are clever. At the very leat it gives you slo-mo replay.
