Hello everyone, I have been playing with a Sony CX7 Handycam for a day now, in the camera I have the choices HD and SD, I would really appreciate it if someone can give me insight on the differences. Obviously HD is clearer, but take someone like me for example. I make movies using iMovie, then burn them to DVD with iDVD, how is HD better. Today, I shot some footage once with HD and again with SD, took both and burned them on a DVD and viewed them on my DVD player, I really can't tell the difference. Is there something I'm doing wrong? I would love to make good use of this camera.
