I'm currently a student at a university in CA and am planning on shooting my final project in HD. We just recently got two new GY-HD100's and I was wondering how to undercrank a shot so that I can have my main subject in the shot moving normally and everyone on the streets around him moving in fast motion. Now I know that when I shoot it I have to have my subject move slower than the rest of the people but I was wondering what I need to shoot it in and play it. I was thinking of shooting in 24p and playing it in 60p but I'm not sure, any feedbaxk would be great.
