In my limited camera experiance, you need to shot in sports mode if available, or with the highest possible shutter speed, I have created successfull slow motion avi's by simply reducing the speed in Premiere Pro(my subject in this case was moving slowly). but i have to say when i tried capturing the skateboarders i suffered with the same issue, added to by the fact that i didnt use a tripod, which i know isnt easy to set up at the top of a ramp LOL |
