What exactly is MUD?

[sammysammy]

ok, here is a better idea of what I'm seeing, in this clip if you freeze the clip at 2.01 (the lady)
0.23 (the car) , that's what I'm seeing , it could be a normal thing, that's why I'm asking, thanks again

A good way to get mud on your GH1 is set it for 1080p 1/50 shutter, hit record, then real subtle like run through a thick forest like a mad man. Replay it and there you have it. I should know, I tried it. Hehe.
