I'm considering the purchase of an HD camcorder. From what I've reading, the TM700 is a good choice. I see that it supports 60 fps at 1080p. Most of the HD content I watch is in 30 fps or 24 fps, as far as I know, and it looks fine. But I'm reading that video shot on these camcorders at 30 or 24 fps will look jerky. I'm just curious why this is.
