There's a lot of interesting video on You Tube concerning fencing and fencing lessons (some interesting because of the just plain oddness of the lessons) but I'm annoyed that so many of the videos are taken perpendicular to the lesson. It's almost impossible, even with good resolution, to see what the blades or actions of the coach and student are.

It you're taking videos of lessons to put on You Tube, use an "over the shoulder shot" to get a good perspective on the actions ...
