There are a number of videos on the web, and this Youtube one is well done:  Youtube Link.
This is a slow motion foil fencing clip of Ota JPN v Sanzo ITA Youtube Link.
There are many videos on parries, footwork etc and sometimes its not so easy to pick the technically correct ones from the not so good ones! 😉
I suggest you speak to your coach after watching a few.  Fencing.net has a nice collection.

And then there are the zany!! search Youtube for Painmen Fencing. ouch.
