Pixelation was likely from the compression or the low-light/speed of the shot. I found that I ended up watching doing the dive through a small viewfinder. I think it's much better to do a site a few times w/o the camera, THEN go and film. It was kind of a bummer to not get to penetrate a bit more, but that camera setup is bulky. Makes everything harder.
I think to get stable shots requires a good tripod of 99% of macro stuff. It's hard to hold a steady shot on a tiny thing and any shaking screws with it (thank god for slow-mo). I'm still working on getting perfect trim but right now I find myself bottom heavy with a lot of weight still on my waist. Unless I fill my feet a bit they will sink and cause me to tip, which is a pain. It's just another thing to tweak.
But alas, I'm out. I got a nice sprain on Sunday after coming back from Madrona Point. Stepping down from a log I rolled my ankle with all my weights and gear on. Ouch.
