I've been wondering the same thing, so thanks for bringing it up in a newer post that I would easily see. I looked at the old threads since people posted links to them.
I don't want to pester people to record for me, so I guess I will have to put a camera on the boards. Just wondering how to get it at a proper position if the boards are too high or too low. I have a camera with a wider lens, but it's new and expensive, so I will have to use my old one with a regular lens (unless I do find someone to record). I don't know if there is a way to edit passerby skaters from video recordings.
My new camera can do 3D recording, but I don't have a 3D TV or monitor to be able to watch them. It would be really cool to watch my skating in 3D to better see what I'm doing than I will with regular video.
