Andre you said: "Man, sometimes you feel like the sparring is so action packed and fast, then you see it on video and it looks like you're moving underwater. Depressing."
I know what you're talking about!
I think it mainly comes from you not being use to seeing yourself on film/video. We never see ourselves as we appear to others, even when you look at yourself in the mirror you still don't "see" yourself like others see you. You have your own "perception" of yourself (good or bad) and this perception is going to mess you up when you compare it to what you "see" of yourself from a third person perspective.
I absolutely hate looking at myself in video/film. But I just have to get over how I "appear" to myself and concentrate on what I'm doing in the film (good or bad) so that I can learn from it.
